摘要：
The features of interaction of ethane with a circulating microspherical solid oxygen-carrier contact in a flow-through riser reactor have been revealed. The effects of temperature and residence time of hydrocarbons (HCs) in the reactor on the performance characteristics of the process have been examined. Under optimum conditions, the conversion of ethane can be as high as 12%, and the selectivity for ethylene is higher than 90%. The results of determination by X-ray photoelectron spectroscopy of relative atomic ratios of elements in the surface layer of the fresh catalyst and catalyst samples discharged from the unit after the set of experiments are presented.
