Definitions
- the present invention consists of a process for the plasmochemical treatment of gas or gas mixture(s) at pressure close to or above atmospheric pressure by plasma flow called PIT PTTM, non-isothermal, generated in pulses , and a device for the implementation of this process in particular for the production of hydrogen and carbon black.
- thermodynamics usually ⁇ 30 - 50%. Efforts to increase this efficiency are in vain since thermal plasmas require temperatures of 5000 to 10,000 K and more to carry out the thermal ionization reaction necessary for their exploitation. At these temperatures, heat losses due to cooling, in particular of the electrodes, are enormous and unavoidable, hence the low efficiency.
- this energy will be used to decompose the molecules of CH4 by activation and electronic shock, without heating the methane gas.
- the energy required for this action is significantly lower than the energy of thermal decomposition (75 kJ/mole) since the decomposition takes place not following heating of the product to be treated but by activation and electronic shock at low temperature.
- the average path length of electrons and activated particles for the targeted reaction, in the plasma, is less than the length of the reactor.
- the average characteristic turbulent diffusion length is less than the characteristic dimension of the reactor.
- One of the aims of the present invention is to determine a PIT PTTM process and the characteristics of the corresponding reactor making it possible to carry out in an optimal manner, taking into account the turbulent nature of the PIT PTTM plasma, the targeted plasmochemical reactions.
- the energy of the electrons of the PIT/PTTM discharge, eU, must be greater than the binding energy H of the molecular components of the treated product: eU »H where e is the electronic charge;
- H is the binding energy of the molecular components of the treated product H.
- the average path length of the electrons Ae and the activated particles Aa with respect to the targeted plasmochemical reaction in the plasma must be less than the length of the reactor L, i.e. d. simultaneously :
- Tn is the temperature of the plasma medium in the reactor
- m* is the ratio mn/me mn is the mass of neutral particles in the reactor
- P is the pressure of the gas or gas mixture in the reactor
- Qen is the mean cross section of the electrons during their inelastic (decomposition) interaction with the neutral particles of the reactive medium of the reactor.
- Qan is the effective average section of the active particles of the plasma during their inelastic interaction with the neutral particles of the reactive medium of the reactor.
- the condition for carrying out the plasmochemical reaction is therefore the one that gives the strongest result of the two equations:
- the average characteristic turbulent diffusion length d must be less than the characteristic dimension of the reactor (mainly the limiting dimension, for example the diameter D): d ⁇ D
- Re V p D/m
- Arei is the average path length of the activated particles with respect to their relaxation:
- Qrei is the mean relaxation cross section of the particles to be treated.
- the condition of completeness of the targeted plasmochemical reaction is therefore:
- the present invention in its process, consists of a treatment of gases and gas mixtures, in particular for the production of hydrogen and carbon black, at atmospheric, sub-atmospheric or superatmospheric pressure, by plasma at intermediate temperatures (PIT PTTM) characterized in that the technological parameters of the process are subject to the following conditions:
- Q is the electronic charge
- U is the voltage at the electrodes;
- H is the binding energy of the molecular components of the treated product.
- L is the active length (i.e. the length of the reactor space limiting the realization of the targeted PIT plasmochemical reaction(s);
- D is the average diameter of the area where the targeted PIT plasmachemical reaction(s) take place;
- P is the pressure;
- Tn is the temperature of the medium (gas or mixture of gases) subjected to the plasmochemical reaction PIT;
- V is the average velocity of the gas or gas mixtures to be treated in the plasmochemical reaction zone PIT;
- k is the Boltzmann constant;
- p is the average density of the gas(es) to be treated
- m is the mean dynamic viscosity of the gas(es) to be treated
- Qen is the average cross section of elastic interactions between electrons and neutral particles of the gas(es) to be treated
- Qan is the average cross section of inelastic interactions between the active particles of the plasma and the particles of the gas(es) to be treated
- Qrel is the relaxation effective cross section of the activated plasma particles
- x is the effective relaxation coefficient.
- m* is the ratio mn/me
- mn is the mass of molecules of gas or gas mixture to be treated. [70] It is important to emphasize that the claimed process not only makes it possible to treat gaseous components but also solid components, for example coal dust, or particles resulting from the spraying of liquid products, such as liquid hydrocarbons, sprayed
- FIG. 1 illustrates a possibility of constructing a PIT PTTM reactor allowing the implementation of the claimed process
- Fig. 2 shows a particular case of realization of a PIT PTTM reactor for the production of hydrogen and carbon black.
- FIG. 7 shows a photo of the reactor as claimed for the manufacture of hydrogen and carbon black.
- FIG. 4 shows the drawing of the reactor for the production of hydrogen and carbon black.
- Fig.5 shows the diagram of the reactor in one of its realizations for the decomposition of methane into hydrogen and carbon black.
- FIGs. 6 a and b illustrate the treatment of a gas (for example decomposition of methane into hydrogen and carbon black) by means of a PIT discharge in the gaseous channel of a vortex (for example of water) ensuring the separation of the Carbon black produces hydrogen, forming a marketable product, and cooling the reaction zone in the PIT reactor.

- PIT plasma As defined in the present invention, PIT plasma as defined
- FIG. 1 The device for implementing the method as defined in the present invention is illustrated by FIG. 1 .
- PIT plasma as defined in document WO 2011/138525 A1, METHOD AND DEVICE FOR GENERATING A NON-ISOTHERMAL PLASMA JET, priority date:
- 05/20172010 is generated by one or more PIT plasmatrons, 1 , installed in a cylindrical or conical reactor 23.
- the reactor is in the form of an airtight container.
- the plasmatron(s) respectively generate one or more PIT plasma jets, 2.
- the electrodes are preferably made of copper or carbon.
- the minimum quantity of electrodes, 3, of a plasmatron is 2. This quantity can be increased to 4, 6, and more depending on the volume of the reactor to be swept by the plasma jets so as to obtain an optimal mixture of the plasma. with the gas to be treated and according to the electricity supply mode.
- the main elements of the plasma jet PIT are the plasma channels, 4, which move chaotically, creating turbulence in the space of the plasma jet 2 through which the electric current passes.
- Each plasmatron is powered by a current pulse source with current and voltage sensors (not shown in Fig. 1).
- the current source can be composed of a transformer with a controlled electric current limiting device (for example system of inductors).
- the frequency of the pulses is equal to the frequency of the primary electric current.
- It can also consist of generators of another type, for example inverters, supplying, for example, each pair of electrodes, connected so that the electric current passes from one electrode to the other, either
- This last mode of connection is preferable because it allows, by varying the amplitudes of current and voltage, as well as the frequency of the pulses, and the time lapses between the pulses, to optimize the structure of the flow of plasma and its contact with the gas(es) or gas mixture(s) to be treated.
- Fig. 1 illustrates the particular case of the decomposition of methane for its transformation into hydrogen and carbon black by PIT plasma.
- the methane feeds the axial part of the plasmatron via a flow regulator, 15, runs along and cools the electrodes, and reaches the reactor where it interacts with the PIT plasma by breaking it down into H2+2C.
- the length 16 and the diameter 17 of the reactor are determined so that the conditions of contact of the PIT plasma with the gas or gases or gas mixtures to be treated expressed in clause 1 of the present invention are respected.
- the optimal values of these parameters are shown in Fig. 2 for the particular case of the production of hydrogen and carbon black with the concrete flow rates as described in embodiment No. 1 of the present invention.
- a protective layer for example of hydrogen.
- a honeycomb device (honeycomb), 7, is provided to standardize the flow rates of flows 5 and 8.
- the hydrogen produced separates from the carbon black particles, 13, via a standard phase separation device 12, and evacuated through the main collector of hydrogen 11 .
- This collector is constructed, for example, so that, by centrifugal effect, the major quantity of hydrogen, 10, is separated from the products of the plasmochemical decomposition reaction.
- the device operates as follows:
- the gas or gas mixtures to be treated enter the plasmatron via a compressor, a regulator and a valve. In the cold state, they run along the electrodes before reaching, in the form of a jet 6, through a honeycomb device (honeycomb) 7, serving to standardize/profile the outline of the distribution of the axial velocities of the / gases or gas mixtures at the inlet of the reactor.
- the PIT plasma composed of channels carrying electric current (1000 - 2000 °C), a relatively cold cloud ( ⁇ 200 - 500 °C) of activated particles and high energy electrons (1 - 2 eV) between the electrodes and propelled by the electrodynamic and hydrodynamic forces (blowing) and forms the reactive turbulent plasma zone 8.
- the decomposition of the gas or gas mixtures to be treated takes place following their contact with the PIT plasma.
- the residues are expelled and separate according to their respective specific masses.
- the light hydrogen 10 bypasses the acute angle of the duct (collector) 11 and, under the action of centrifugal forces, is evacuated from the reactor through the compressor output regulator.
- Some of the hydrogen produced is bypassed, as shown in Fig. 1, through flow regulators and returned to the reactor to create the protection zone 5 and the electrode protection zone 8.
- the heavy components possibly produced during the plasmochemical reaction in the reactor, for example, carbon black 13, in the case of the decomposition of methane, are evacuated and separated through standard devices such as, for example filters (separator 12).
- FIG. 2 corresponds to the case where the gas or gas mixtures to be treated, which reach the reactor 23, are separated from the protective and cooling flow 5 by a conical or cylindrical pipe 18.
- FIG. 2 in particular, illustrates the case of the production of hydrogen and carbon black from methane.
- all the plasmochemical reactions of transformation of the gas or gas mixtures to be treated take place inside the tube 18, cylindrical or conical, not allowing access to oxygen or air in his pregnant.
- the reaction products are discharged through the end of this tubing.
- the tubing 18, preferably, is made of insulating and refractory material, for example quartz.
- a swirl device 22 for example in the form of inclined fins, fixed at an angle of attack relative to the axis of the plasmatron PIT, an angle whose value can vary between 0° and 80°, can be placed at the output of the plasmatron, for example at the end of the electrodes 3. It can happen that residual products or portions of gas or gas mixtures not having completely reacted with the PIT plasma (for example, not having completely decomposed by plasmochemical reaction) are evacuated from the reactor, mixed with the gas produced.
- the device of Fig. 2 provides for a gas-dynamic separation of these products 19, their evacuation using the conduits 19, and their reinjection, via a regulator compressor with valve, into the reactor, for their decomposition, simultaneously with that of the / gases or gas mixtures injected into the reactor.
- Fig. 3 is a photo of the central part of the reactor, in operation. It illustrates the chaotic nature of the PIT/PTTM plasma jet in the hydrogen and carbon black manufacturing process.
- FIG. 4 is a drawing of the claimed reactor in the case of the manufacture of hydrogen and carbon black.
- FIG. 5 corresponds to a simplified diagram of the PIT reactor for the decomposition of a gas (for example methane) in which the body of the reactor 23 is a cylindrical tube (for example made of quartz) fixed to the PIT plasmatron, the length of which is determined empirically depending on the degree of completion of the process of decomposition of the incoming gas.
- the plasmatron and/or the reactor are provided with means 31 for causing a gas vortex so as to project towards the periphery, under the effect of centrifugal forces, the heavy components of the plasmochemical reaction (for example the particles of carbon black ).
- Fig 6 illustrates the case where the claimed reactor essentially consists of a vortex device 27 ensuring that the PIT discharge takes place in the axial channel of the vortex.
- the incoming liquid water in particular
- the PIT discharge takes place in the gas channel (of CH4) formed by the swirling of the water.
- the flow of water drags the plasma in its swirling motion.
- the heaviest components of the plasmochemical decomposition reaction carbon black in the case of the decomposition of methane
- Fig 6a corresponds to the case where the water of the vortex is introduced tangentially into the body of the vortex by an orifice of elongated section (parallelpipedic) distributing the water longitudinally along the body of the vortex 24, 26.
- Fig 6b corresponds to the case where the water of the vortex is introduced tangentially into the body of the vortex locally through an orifice of circular section 24, 26.
- the device claimed is characterized in that the PIT discharge is located in the gaseous channel formed by a vortex fed tangentially by a liquid such as water, so as to separate the heavy components from the light components formed in the PIT/PTTM discharge, cooling the device and forming a marketable product, for example composed of water and carbon black.
- the numbers indicated have the following meaning:
- Electrodes [107] 3. Electrodes; [108] 4. PIT plasma channels carrying electric current;
- the present invention is preferably used for the decomposition of the gases or gas mixtures introduced into the reactor 23, more particularly for the production of hydrogen and carbon black by decomposition plasmochemistry of methane. It can be exploited to carry out any other process for transforming gases or gaseous mixtures by plasmochemical means using a PIT plasma.
- the present invention is very useful for transformation by decomposition under the effect of the impacts of electrons and active particles on the molecules populating the surface of solid particles, for example coal dust or particles resulting from the spraying of liquid products such as, for example, hydrocarbons.
- the present invention both the method and the claimed devices, allows, by choosing the parameters of the PIT process according to the equations mentioned above, in particular the voltage U between the electrodes, as well as the configuration of the systems of feeding the PIT/PTTM discharge zone containing solid particle dosing devices such as coal particles or particles resulting from the spraying of liquid products, for example hydrocarbons, the decomposition into gaseous components under the effect of impacts electrons and active particles from the plasma PIT PTTM molecules populating the surface of solid particles, for example coal dust or particles resulting from the spraying of liquid products such as, for example, hydrocarbons.
- Base gas introduced into the reactor methane (CHU) or natural gas.
- Base gas introduced into the reactor natural gas.
