The coaltomethanol (CTM) is an important technical route for methanol production. The process suffers from high CO2 emission and low energy efficiency due to the mismatch of H/C (hydrogentocarbon) ratio between raw coal and products. Hydrogen production from renewable energy can be introduced into the system to meet the H/C ratio.
