METHOD FOR PRODUCING OLEFIN HAVING 2-4 CARBON ATOMS AND METHOD FOR PRODUCING PROPYLENE

摘要

A method for producing an olefin having 2-4 carbon atoms, which comprises a step wherein at least one catalyst (D) that is selected from the group consisting of the catalysts (A)-(C) described below is reacted with a synthetic gas in the coexistence of a dispersion medium in a Fischer-Tropsch reaction. The catalyst (A) is a catalyst that contains iron and one to three elements that are selected from the group consisting of alkali metals and alkaline earth metals. The catalyst (B) is a catalyst that contains cobalt, provided that the catalyst (B) is a catalyst other than catalysts which are obtained by reducing cobalt ions and iron ions in a dispersion liquid or a solution that contains cobalt ions, iron ions and a dispersant which is interactive with the cobalt ions and the iron ions. The catalyst (C) is a catalyst that contains nickel or ruthenium.
