Directly making light olefins via CO hydrogenation is a promising process to obtain a non-petroleum based supply of alkenes. Limited by the ASF distribution function of Fischer-Tropsch synthesis,the yield of light olefins (C2-C4) can not reach the desired levels, which is a great challenge to overcome.Beginning with a brief introduction of F-T synthesis, this paper provides a review of current research,including thermodynamic analysis, the ASF distribution function, the reaction performance of CO hydro-genation and slurry reactor studies. The problems currently faced by this research area are presented atthe end of the article.
