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 ...
