Abstract

A CO₂ laser pyrolysis technique has been used to prepare high surface area (-120 m2/gm) Fe_x Si_y C_z materials. These materials have been tested as catalysts for the reaction of hydrogen with carbon monoxide to form hydrocarbons. The reaction was studied as a function of temperature (250°C - 350°C) and feed-gas composition (H2/CO = 3:1, 1:1, 1:2). The Fex Siyz C materials show very high selectivity for the formation of low molecular weight olefins, with over 50% of the product being C₂-C₄ olef ins. They are moderately active and retain their activity and selectivity over long periods of time. In addition, the formation of undesirable CO₂ by-product is substantially reduced relative to other reported catalysts. The observed product distributions are, in general, consistent with the Schulz-Flory polymerization mechanism.
