Direct catalytic conversion of synthesis gas to lower olefins
- Coal Division, Indian Institute of Chemical Technology, Hyderabad 500 007 (IN)
Direct conversion of synthesis gas to lower olefins has been considered as a possible solution to meet the growing demand for chemical feedstocks such as ethylene, propylene, and butylenes. This review covers the various catalyst systems and operating conditions that have been used in meeting this objective. Though the product distribution in Fischer--Tropsch synthesis is governed by the existence of an Anderson--Schultz--Flory polymerization model, certain modifications in the catalyst formulations have produced a shift toward lower molecular weight olefins. At the present time, the yields and selectivities of lower olefins are far from optimal, but continued research efforts in this area may lead to the development of stable catalyst systems capable of producing highly desirable distributions of lower olefins.
