Example Embodiment
[0015] Specific embodiment 1: The electrochemical reforming system for dry reforming of methane and carbon dioxide in this embodiment includes a plurality of electrolytic cell sheets, a reactor 1 and an external power source 2; the plurality of electrolytic cell sheets are arranged in parallel in the horizontal direction Inside the reactor 1, the electrolytic cell sheet includes an electrolyte membrane 3 and two porous electrodes 4. The upper and lower surfaces of the electrolyte membrane 3 are respectively connected to the two porous electrodes 4, and the porous electrodes 4 are connected to an external power source 2 through wires. Connected.
[0016] The external power source in this embodiment is direct current or alternating current.
[0017] The electrolytic cell of the system of this embodiment is composed of electrolytes and electrodes. If the power source is direct current, the dissociation of carbon dioxide occurs in the cathode to generate carbon monoxide and oxygen ions...
Example Embodiment
[0018] Specific embodiment two: This embodiment is different from the specific embodiment one in that the reactor described in 2 is a ceramic tube or a glass tube. Others are the same as the first embodiment.
Example Embodiment
[0019] Specific embodiment 3: The construction method of an electrochemical reforming system for dry reforming of methane and carbon dioxide in this embodiment is as follows: 1. The electrolyte material is prepared into an electrolyte film by a casting method, and then sintered at high temperature to form a dense electrolyte film 3; 2. Use the screen printing method to prepare electrodes on both sides of the dense electrolyte membrane 3, and then use a pore former and high-temperature calcination to obtain the porous electrode 4; 3. Use the screen printing method to prepare a bus layer on the porous electrode 4, then After sintering at high temperature, the electrolytic cell flakes are obtained; 4. Put n electrolytic cell flakes in the reactor 1, and then connect with the external power source 2 through the porous electrode 4 and the wire to obtain the electrochemical reforming system of methane carbon dioxide dry reforming. n≥1.
[0020] The electrochemical reforming method prop...
