AI Technical Summary
Existing methanol production methods rely on syngas as a raw material, which has problems such as high energy consumption, complex process control, easy catalyst deactivation, and environmental pollution, as well as resource scarcity.
Using alumina or molecular sieve catalysts, especially mordenite, ZSM-5, ZSM-23, Na-type Y molecular sieve, and H-type Y molecular sieve, water and carbon monoxide are directly converted into methanol through a thermal catalytic water carbonylation reaction. The reaction conditions are mild, and the catalyst is activated and then comes into contact with the raw materials.
A one-step method for producing methanol from water and carbon monoxide has been achieved, reducing dependence on traditional fossil fuels, improving efficiency, and minimizing environmental impact. The catalyst exhibits good operability and selectivity.
