- the discharge unit 110 is composed of an electrode 120 for discharging and a flange tube 112 containing the electrode.
- the compression section 140 is provided to reduce the flow rate of the gas decomposed in the discharge section 110 and increase the flow rate in the next separation section 140.
- the separation unit 140 a plurality of gas species are separated into two types according to the weight using the centrifugal force on the gas generated by the claws 142. The operation of these parts will be described in detail below.
- the dimensions shown in FIG. 1 are examples, and the unit is mm.
- the cylindrical pipes in each section are made of stainless steel (SUS).
- a gas mainly composed of methane (CH 4 ) is injected into the gas decomposition / separation device 100, and hydrogen (H 2 ) and carbon are discharged from the discharge unit 110 using discharge.
- FIG. 2 shows the configuration of the electrode 120 of the discharge unit 110 in FIG. 1 in detail.
- the electrode 120 has a configuration in which two electrodes facing each other are combined. Each electrode protrudes a plurality of stainless steel screw (screw) electrodes 122 at approximately equal intervals from a square insulator 124 on a flat plate. Each screw electrode 122 is electrically insulated.
- the pulse electrodes 15 2 are connected to one screw-shaped electrode, each of which has a diagonal relationship between the electrodes facing each other.
- a mesh-like electrode 126 is provided below the electrode that performs this discharge.
- a negative bias potential (V 0 ) is applied to the mesh-shaped electrode 122 with respect to the screw-shaped electrode 122 by a DC power supply 154.
- a pulse-like voltage is applied from the pulse power source 152 to the screw-like electrode 122 to cause a discharge between the electrodes, thereby converting methane (CH 4 ) into hydrogen (H 2 ). And carbon (C).
- This discharge occurs between the plurality of screw electrodes.
- the carbon particles decomposed from the methane gas are dropped downward by their own weight as much as possible, and are removed at the discharge portion 110.
- the bias voltage to the mesh electrodes 126 is adjusted to set the potential difference for guiding the carbon particles downward to an optimum value.
- the mixed gas containing hydrogen generated from methane in the discharge unit 110 is compressed by the compression unit 13 It is led to the separation section 140 through 0.
