Abstract

Oxidative conversion of ethane to ethylene over alkaline earth metal (viz. Mg, Ca, Sr and Ba) promoted La2O3 (alkaline earth/La=0.1) in presence of steam (steam/C2H6=1.0) and limited O2 has been studied at different temperatures (700-850°C), C2H6/O2 ratios (4.0-8.0) in the feed, and gas hourly space velocities (5x104 -20x104 cm3 g-1 h-1). Among these catalysts, the Sr promoted La2O3 (Sr/La=0.1) catalyst showed best performance in the process. High selectivity (>80%) for C2+ olefins at 50-70% conversion of ethane could be obtained at 800-850°C and very short contact times (
