Does methanol reformation for hydrogen production fall under the category of hazardous pyrolysis chemical processes?
Thread Content
I would like to ask whether hydrogen production via methanol reformation falls under the category of hazardous chemical processes involving cracking?
Methanol and water vapor undergo, under certain temperature and pressure conditions and in the presence of a catalyst, methanol cracking reactions as well as carbon monoxide conversion reactions, resulting in the production of hydrogen and carbon dioxide. This is a gas-solid catalytic reaction system involving multiple components and reactions. The reaction equations are as follows: CH3OH→CO+2H2 (1) H2O+CO→CO2+H2 (2) CH3OH+H2O→CO2+3H2 (3) The H2 and CO2 produced by the reforming reactions are then separated using pressure swing adsorption (PSA) to obtain high-purity hydrogen. Operating conditions: 250-300°C, 1-5 MPa. Pyrolysis and pressure swing adsorption processes are mature chemical engineering processes. Therefore, methanol reformation for hydrogen production does not belong to hazardous pyrolysis chemical processes.
