As the title suggests, the process of producing carbon monoxide from carbon dioxide seems reasonable and economical; however, there are hardly any industrial applications for it. Let’s discuss its feasibility as well as the prospects for industrialization if it is feasible – particularly in terms of its environmental benefits Reaction equation: CO2 + C = 2CO. Personal opinion: Theoretical research on this approach is still insufficient, so the prospects for industrial application remain unclear. We welcome everyone to engage in active and in-depth discussions. Thank you!
CO2+CH4=2CO+2H2: Ni-based catalyst at 630 DegC. It seems pointless to use this process for producing hydrogen through conversion, rather than for extracting CO
I’m new here; does this transformation process generate a lot of carbon dioxide as well?
Study it carefully*; discussions are welcome
Our gas generation furnace from 20 years ago used a mixture of carbon dioxide and oxygen as the gasification agent. Now, the purified gas also has the separated carbon dioxide sent to the old gas generation furnace for gas production. It is said that a carbon tax and carbon coins will be introduced soon, which makes our system even more valuable

The first is to use solar energy to directly decompose CO2, which requires relatively high temperatures. The second idea involves using a chemical cycle: selecting a crystal similar to a catalyst, causing it to release the oxygen from its lattice at a certain temperature, then introducing CO2 to take away the oxygen atoms from CO2 and thus form carbon monoxide, after which the crystal is restored to its original state. Of course, it's still a long way off from being truly practical

This reaction should be an endothermic reaction that requires heat. Environmental benefits can only be achieved by finding a suitable catalyst.
The reaction of CO2 with C has long been industrialized; the CO generation furnaces from the Saiding Coal Chemical Center have even been introduced in Taiwan
That’s correct; the Coal Chemical Engineering Design Technology Center (formerly part of Caiding) holds patents for carbon monoxide generators, and it has installed one set at the Chanchang Mailiao Petrochemical plant in Taiwan.
