Production of Alcohols and Olefins from CO and H2 on a Cobalt Catalyst at High Pressures and in the Gas Circulation Mode

The results of a study of the synthesis of products from CO and H 2 on a supported industrial Co–Al 2 O 3 /SiO 2 catalyst under medium and high pressures in the gas circulation mode are presented. It was found that an increase in pressure from 2.0 to 8.0 MPa led to an increase in the amount of formed alcohols and synthesis olefins by factors of 10.5 and 2.0, respectively. It was determined that alcohols obtained in the synthesis were not the products of olefin hydration. The effect of an increase in selectivity for C 5+ products with temperature at a high pressure in the gas recirculation mode, which is atypical for the Fischer–Tropsch synthesis, was confirmed.
