Fe-based catalysts are often used for various fields of catalytic reactions. F-T (Fischer-Tropsch) reaction is a representative example. It is well known that the Schulz-Anderson-Flory law determines the distribution of hydrocarbons in F-T reaction. To overcome this limitation, the composite catalysts comprised of Fe-based catalyst and zeolite have been examined. Although these composite catalysts produced branched hydrocarbons and improved the selectivity of hydrocarbons, the distribution was essentially restricted by the Schulz-Anderson-Flory law in almost cases. We have already reported that hydrocarbons were obtained efficiently from carbon dioxide and hydrogen over another type of the composite catalysts which are prepared by the physical mixing of Cu-based catalysts and zeolite. This catalytic system combining methanol synthesis and MTG (Methanol-to-Gasoline) reaction presents a novel method for hydrocarbon synthesis which is free from the Schulz-Anderson-Flory law. We recently found that, in the hydrogenation of carbon dioxide, Fe-ZnO/HY composite catalyst produced hydrocarbons with a similar distribution to the composite catalysts comprised of Cu-Zn-chromate and zeolite, while Fe-ZnO catalyst acted as a typical F-T catalyst to afford hydrocarbons with the Schulz-Anderson-Flory distribution. This presentation describes the entire studies of the hydrogenation of carbon dioxide over Fe-ZnO/HY.
