  • Method of manufacturing olefin having 2 to 4 carbon atoms by Fischer-Tropsch reaction
    Patent number: 9139489
    Abstract: Provided are a method of manufacturing an olefin having 2 to 4 carbon atoms including: reacting a catalyst with synthesis gas through a Fischer-Tropsch reaction, thereby obtaining the olefin having 2 to 4 carbon atoms, in which the catalyst is a catalyst obtained by reducing the iron ion and the cobalt ion in a dispersion liquid or a solution containing the iron ion, the cobalt ion and a dispersant that interacts with the iron ion and the cobalt ion, and a method of manufacturing propylene, which uses the above manufacturing method.

  • METHOD OF PRODUCING OLEFIN HAVING 2 TO 4 CARBON ATOMS AND METHOD OF PRODUCING PROPYLENE
    Publication number: 20150225309
    Abstract: A method of producing olefin having 2 to 4 carbon atoms, including a process of reacting at least one kind of a catalyst (D) selected from the group consisting of below catalysts (A) to (C) with synthesis gas in the presence of a dispersion medium through a Fischer-Tropsch reaction, in which the catalyst (A) contains iron and one to three kinds of elements selected from the group consisting of alkali metal and alkali earth metal, the catalyst (B) contains cobalt, provided that the catalyst (B) is a catalyst except a catalyst obtained by reducing a cobalt ion and an iron ion in a dispersion liquid or a solution containing the cobalt ion, the iron ion and a dispersant that interacts with the cobalt ion and the iron ion, and the catalyst (C) contains nickel or ruthenium.
