SYSTEM AND METHOD FOR DEHYDROGENATING ISOBUTANE TO ISOBUTYLENE

摘要

A system and a method for dehydrogenating isobutane to isobutylene are disclosed. The system comprises a fixed bed dehydrogenation reactor. The fixed reactor bed in the fixed bed dehydrogenation reactor includes a catalyst layer, a first material adapted to improve the flow distribution in the fixed reactor bed, a second material adapted to improve the thermal distribution in the fixed reactor bed, and a third material adapted to improve both the flow distribution and the thermal distribution in the fixed reactor bed. The first material covers a top, a bottom, and at least a portion of a side surface of the catalyst layer of the fixed reactor bed. The second material and the third material both are evenly distributed in the catalyst layer.
