摘　　要：The study reports progress in developing a molybdenum carbide-based catalyst for co-processing ethane and CO_(2).The cobalt promoting of molybdenum carbide improved the activity and stability of ethane transformation in the presence of CO_(2) substantially without any impact on ethylene selectivity.The Mo-Co supported catalyst also showed interesting performance in catalyzing ethane dry reforming and that application could be a perspective further use for this system.In addition,the comprehensive analysis of mono-and bi-metallic catalysts revealed that Co-promoting prevented rapid Mo-carbide oxidation.Further,tuning operation conditions allowed to control catalyst’s selectivity and maximize CO_(2) utilization or ethylene formation.
