Abstract: Oxidative dehydrogenation of ethane to ethylene in presence of steam (steam/C2H6 mole ratio =1.0) and limited O2 (C2H6/O2 mole ratio ≥ 4.0) over a SrO-promoted Sm2O3, supported on low surface area macroporous silica-alumina commercial catalyst carrier (SA5205, obtained from Norton Co. USA) has been thoroughly investigated. Effect of different process parameters such as temperature (700-850°C), C2H6/O2 feed ratio (4.0-8.0) and gas hourly space velocity (5×104- 20×104 cm3g-1h-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.
