Developing a laboratory scale or pilot scale chemical process into industrial scale is not trivial. The direct conversion of CO2 to methanol, and concomitant production of hydrogen from water electrolysis on large scale, are no exception. However, when successful, there are certain benefits to this process over the conventional process for producing methanol, both economic and environmental ...

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 ...

Methanol Production. Synthesis gas can also be used to produce methanol, and CH 3 OH. The current technology for making methanol is fairly mature. Typically, natural gas is used as the feedstock, which is steamreformed to make CO and hydrogen: CH 4 + H 2 O → CO + H 2 This equation is not rendering properly due to an incompatible browser.
