Carbon monoxide molar fraction. Methanol (MeOH) is one of the candidate fuel products for the conversion of CO2 through a chemical process. The Gibbs free energy of the biomass cannot be calculated because it is a non-conventional component. 6 Syngas Compressor (CMP-200) The syngas process stream is brought to the optimal operating temperature and pressure of the methanol synthesis reactor using an inter-stage compressor. For this purpose, hydrogen from electrolysis of water using a renewable electricity source can be considered as a carbon-free source. Although the majority of methanol synthesis is based on natural gas as feedstock, coal-derived syngas is also used; coal/solid feedstocks are used to make 9% of the worldwide output of methanol (Gasification,Higman C., Van der Burgt M., 2003).
