The block flow diagram of the CO 2 hydrogenation option for methanol production ( CCUmethanol) is shown in Fig. 4. In this option, the feedstock is a mixture of CO 2 and highpurity hydrogen. The carbon capture unit captures CO 2 from the flue gas, and the water electrolysis unit produces the required hydrogen.

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 ...
