Production of High-Valued Chemicals from Natural Gas and Light Hydrocarbons.Final Report, January 1990-February 1991

摘要

The objective of this project is to explore the production of olefins andoxygenates via oxidative coupling and oxy-dehydrogenation of natural gas and light hydrocarbons. The oxidative coupling of methane to propane and the coupling of ethane to ethane to form C4's was demonstrated using the IGT Li/B/MgO catalyst. Under the conditions for oxidative coupling, oxy-dehydrogenation also occurred and was the predominant reaction. A brief comparison of ethane oxy-dehydrogenation and conventional ethane-steam cracking was made. The oxy-dehydrogenation of ethylbenzene to styrene was performed over IGT's Li/B/MgO catalyst and other catalysts developed in this project. The best yield was 25.8% styrene per pass. A total of 87 oxidative processing runs were made. Mass balances, conversions, and yields are reported.
