Title
C2-C5+ olefin production from CO2 hydrogenation using ceria modified Fe/Mn/K catalysts
Abstract

Improvement in CO2 conversion to value-added hydrocarbons is reported using a formulated bifunctional catalyst that combines reverse water-gas-shift (RWGS) and Fischer–Tropsch chain growth activity. Adding the ceria prior to the deposition of CO2 hydrogenation catalysts results in an approximate 22% increase in CO2 conversion. The calcination temperature and the consequential size of the ceria particles are also pivotal in tailoring the catalyst's activity and selectivity.

► A bifunctional catalyst was designed for conversion of CO2/H2 to valuable HC. ► The catalyst incorporates both RWG activity and chain growth activity. ► The catalyst increases CO2 conversion by 22% and olefin production by 5%. ► Calcination temperatures play a role in the catalyst's activity and selectivity.
