The FischerTropsch process is a catalytic chemical reaction in which carbon monoxide (CO) and hydrogen (H 2) in the syngas are converted into hydrocarbons of various molecular weights according to the following equation: (2n+1) H 2 + n CO → C n H (2n+2) + n H 2 O. Where n is an integer. Thus, for n=1, the reaction represents the formation of ...
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.
