摘要
Abstract
Effect of impurities,such as ethyl mercaptan,methyl alcohol,butane and 1-butylene,on the performance of Pt-Sn-K/Al2O3 catalyst in the reaction of isobutane dehydrogenation to isobutene was investigated on a fixed bed reactor,and the product was analyzed by gas chromatography. The results showed that ethyl mercaptan,methyl alcohol,butane and1-butylene all had great influence on the isobutane conversion and isobutene selectivity of Pt-Sn-K/Al2O3 catalyst under the reaction condition of isobutane dehydrogenation to isobutene,i.e. at the temperature of 580℃,pressure of 0.1MPa,feedstock of H2/i-C4H10(V)= 2,total space velocity GHSV= 2000h−1,GHSV(i-C4H10)= 667h−1; and the higher the impurities content was,the greater the influence was. Furthermore,how the impurities caused the deactivation of catalyst was analyzed.关键词
