Integrated CO2 capture and one-pot production of methanol.

The capture, storage, and utilization (CSU) of CO2 to produce methanol which can be used as a fuel, fuel additive, and precursor in organic synthesis is an area of fascinating research. This directly influences the reduction of the CO2 concentration by capturing CO2 from industrial and automobile emissions. The development of integrated CO2 capture and conversion to a fuel and fuel additive has garnered considerable attention as it eliminates costly processes to produce pure CO2. This contribution presents a summary of integrated CO2 capture and conversion to methanol (MeOH) using amine-assisted and alkali hydroxide-assisted one-pot systems. The superiority of the alkali hydroxide-based system to the amine-based system for the conversion to MeOH is systematically presented.
