CO2 hydrogenation to alcohols over highly dispersed Co/SiO2 catalysts derived from acetate

Article abstract of DOI:10.1246/cl.2001.904

Highly dispersed Co(A)/SiO₂ catalysts were prepared from acetate, and used for CO₂ hydrogenation to alcohols under the reaction conditions of T = 493 K, P = 2.1MPa, H₂/CO₂ = 3/1, and GHSV = 2000 h^-1. Catalytic activity was greatly improved by adding a small amount of Ir to the catalyst, and methanol (ca. 20%) was formed, in contrast with Co(N)/SiO₂ catalyst derived from nitrate. Ethanol selectivity was increased up to 8% by adding Na salt to the Ir/Co(A)/SiO₂ catalyst.
