Abstract

The study investigates, for the first time, the effects of the composition of a catalytic dispersion on its performance in three-phase hydrogenation of a CO+CO2 mixture in a continuous stirred-tank slurry reactor (CSTR) without pre-separating the feed mixture. It is shown that the selectivity towards specific hydrogenation products can be controlled by varying the choice of nature of the metal of nanosized dispersions. Specifically, Co- and Fe-based dispersions mainly promote the production of C2+ hydrocarbons, and Ni-based samples lead to the predominance of methane in the products.
