Definitions
- the invention relates to a process for the production of hydrogen.
- Degussa process is based on monosilane as starting material.
- the gaseous monosilane is, even in a mixture with other inert gases, deposited at temperatures above 1000 0 C on silicon.
- Sense of high temperatures is mainly to obtain massive polycrystalline silicon, which is easily processed for further purification, z. B. by melting.
- Literature information shows that at pressures between 0.13 and 6.61 MPa and temperatures of about 400-600 0 C agglomerated spherical particles with a mean diameter of 3 microns arise.
- Other sources indicate the beginning of the decomposition at 450 0 C and report a 75% decomposition at 500 0 C and complete conversion at 700 0 C.
- low reaction temperatures lead to finely divided or even amorphous reaction products, as well as the Processes that produce finely divided, fumed silicon gas as the major product require further processing of the powder to eventually allow processing to bulk silicon.
- Si-H compounds are not stable in basic solutions since Si has high oxophilia. Already the alkali content of glasses is sufficient to initiate the decomposition. Likewise, decomposition occurs in acidic solutions, albeit at a slower rate than in the alkaline pH range.
- SiO 2 layers can be produced from various substituted silanes or else Si-H compounds in a mixture with water vapor under low pressure in CVD processes.
- the thermal conversion of silanes with Wasserdatnpf or oxygen has the advantage of high hydrogen efficiency.
- the process is emission-free.
- the resulting hydrogen has a high purity and is therefore suitable above all for use in PEM fuel cells.
- Fig. 1 is a process flow diagram according to the kompelxesten
- This reaction can be the basis of a power plant process.
- the reaction is carried out according to equation 1 at a temperature of 400 0 C and a pressure of 3 bar in a reactor.
- the heat released is used to evaporate the water supplied to the reactor.
- the excess heat is dissipated to the environment.
- the resulting hydrogen is fed to a PEM fuel cell (FC) (version 1).
- FC PEM fuel cell
- reaction also takes place at higher pressures (eg 80 bar)
- electrical energy can additionally be obtained by relaxing the hydrogen in front of the fuel cell in a gas turbine.
- the solids must be separated by a cyclone.
- Part of the heat released from the reactor can also be used for the evaporation of additional water so that it can be fed to a steam turbine (version 2).
- the energy efficiencies shown in Table 1 are based on the calorific value of monosilane, which is calculated to be 44.26 MJ / kg (methane comparison: 50 MJ / kg). If the hydrogen is not supplied to the fuel cell, the efficiencies additionally take into account the calorific value of the hydrogen (120 MJ / kg) instead of the generated electrical energy.
- the isentropic efficiencies of the engineered components were chosen to be 90% for the gas turbine and mid-pressure turbine, 89% for the high-pressure turbine, 87% for the low-pressure turbine, and 85% for the pumps.
- the live steam parameters are 600 0 C and 300 bar or 600 0 C during reheating.
- the heat of the solids is used up to a minimum temperature of 100 0 C for heating in the steam cycle.
- the released heat of the fuel cell is not used so far.
- the amount of heat released will be less since SiO 2 does not accumulate as crystalline quartz and the reaction product may also be hydrate dependent on reaction temperature and time (containing Si-OH), thereby changing the stoichiometry of the reaction.
- poly- or oligosilanes and, in particular, monosilane are more suitable as hydrogen storage, since more hydrogen can be liberated based on the educt mass (Si + 2 H 2 O -> SiO 2 + 2 H 2 ).
- Neglecting the water used and other catalysts or reactants a hydrogen storage density of about 14%, for (SiH 2), however, arises for elemental Si x 20% and SiH 4 25%.
- the storage capacity for this (SiH 2 ) x would be about 6.5%, for SiH 4 it would be 12.5%
- the recovered silicon can not be reversibly converted back to the silanes by simple hydrogenation reactions the known alkaline hydrogen representation of elemental silicon after
- the hydrogen produced in this way is, after separation of the resulting particles, except for residues of water vapor, pure and thus particularly suitable drove use in PEM fuel cells. Due to the high storage capacity, the application of the method is also conceivable in mobile systems. Instead of an electrochemical reaction of course, a combustion of the hydrogen or the hydrogen / steam mixture in an internal combustion engine of any design is possible. However, for the application of this technology, it must be ensured that the particle load of the hydrogen gas produced is as small as possible is to minimize abrasion on moving parts. Alternatively, a separation of combustion chamber and working gas volume is conceivable, for example in a Stirling engine.
