Abstract
Oxidative conversion of ethane to ethylene over a SrO-promoted Er2O3 supported on low-surface area macroporous silica-alumina commercial catalyst carrier (SA5205, obtained from Norton Co., USA) in presence of steam (steam/C2H6 mole ratio = 1.0) and limited O2 (C2H6/O2 mole ratio = 4.0) has been thoroughly investigated. Influence of different process parameters such as temperature (700-850°C), C2H6/O2 feed ratio (4.0-8.0) and space velocity (50, 000-200, 000 cm3 g-1 h-1) on the conversion of ethane and product selectivity in the process has been studied. High selectivity (≥80%) of C2+ olefins at 50-70% conversion of ethane could be obtained at very low contact time without coke deposition on the catalyst at 800-850°C.
