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.
Conventionally, the coaltomethanol process generates a substantial amount of CO 2 emissions with a low yield of methanol. In this study, we propose the conceptual design development of coaltomethanol process using captured CO 2 from the gasification plant by implying process intensification.
Methanol production using fossil fuels, mainly from natural gas . and coal, is a mature technology [13]. Renewable hydrogenbased methanol as an alternative fuel is widely investigated by researchers worldwide [1,2,13,2224].
