For coalbased methanol production, coal is intermingled with O 2 of AS and subsequently subjected to CG for producing crude syngas. The cryogenic separation technology is primarily used in the AS for oxygen production, which is a high energy consumption process (Xiang et al., 2014).Because of the small hydrogentocarbon (H/C) ratio in coal, WGS process is used to convert CO and H 2 O to CO 2 ...

Developing a laboratory scale or pilot scale chemical process into industrial scale is not trivial. The direct conversion of CO2 to methanol, and concomitant production of hydrogen from water electrolysis on large scale, are no exception. However, when successful, there are certain benefits to this process over the conventional process for producing methanol, both economic and environmental ...

The process flow of Route 3 is similar to that of Route 1 . Route 3 uses a coelectrolysis unit and a MeOHsynthesis unit. In the coelectrolysis unit, steam and CO 2 are reduced to syngas by the SOEC after pressurization (up to ~ MPa). The syngas is then sent to the methanolsynthesis unit and converted to MeOH.
