Syngas conversion offers a potential alternative to flaring or reinjection for monetization of associated gas. However, certain deployment applications disfavor the hydroprocessing infrastructure required to upgrade the linear paraffin wax product for blending or transport. We describe in this talk Chevron's Gas Conversion Catalysis technology, a commercially viable hybrid syngas conversion catalyst comprising both a Fischer-Tropsch active metal and a zeolite component. This hybrid integral catalyst truncates the Anderson-Schultz-Flory (ASF) distribution to provide a high yield of liquid hydrocarbon product without a separate solid wax phase. The lack of a wax product eliminates the need for costly downstream hydroprocessing. This talk will focus on catalyst and process development including a discussion on the effect of zeolite properties and process conditions.
