ZSM-5 SUPPORTED IRON CATALYSTS FOR FISCHER-TROPSCH PRODUCTION OF LIGHT OLEFIN
IntroductionWith the increase in the cost of petroleum products due to depletion of oil reserves, alternative methods for synthesizing hydrocarbon fuels such as the Fischer-Tropsch synthesis (FTS) have again received considerable attention. Fischer-Tropsch synthesis is an important technology in the production of liquid fuels and chemicals from syngas derived from the gasification of coal, the reforming of natural gas, or other carbon-containing materials. Several metal catalysts can be used for the Fischer-Tropsch synthesis; however, only iron and cobalt catalysts appear to be economically feasible on an industrial scale. Co catalysts yield mainly straight-chain hydrocarbons while Fe catalysts are more useful when the H2/CO ratio is low (because of the water-gas-shift activity of Fe) or for the production of alkenes, oxygenates, and branched hydrocarbons, depending upon the promoters and process conditions employed. Also, iron based composite catalysts prepared by physical mixture of the iron component and the zeolite have been studied to understand the influence of nature of zeolite on the activity and product selectivity. However, studies on the Fe catalysts prepared by using various methods are scarce, particularly aiming at maximizing the light olefin yield 1,2.
