Methanol Cracking Process PrincipleThe mixed superheated steam of methanol and water prepared in a certain proportion passes through the catalyst under certain temperature and pressure conditions, and at the same time, catalytic cracking reaction and carbon monoxide shift reaction occur, and finally a mixture of hydrogen and carbon dioxide is generated. The methanol water cracking reaction is a multi-component, multi-reaction gas-solid catalytic complex reaction system. 重要反映落實為： CH?OH <=> CO+2H?-90.7kJ/mol CO＋H?O <=> CO?+H?+41.2kJ/mol 總反饋為： CH?OH＋H?O <=> CO?+3H?-49.5kJ/mol
After the reacted mixed gas is heat exchanged, condensed, and separated, a converted gas with a hydrogen content of ~74%, a CO? content of ~24.5%, and a CO content of ~0.5% is obtained. The single-pass conversion rate of methanol is more than 95%, and unreacted raw materials (Methanol, desalinated water) return to the raw material system for recycling. The reformed gas is sent to a pressure swing adsorption device for separation and purification to obtain high-purity product hydrogen.
