摘要：

本文制备了一系列Sb2O3/Co-ZSM-5分子筛催化剂,并尝试用于乙烷氨氧化反应.结果显示,引入适量的Sb2O3可以明显提高催化剂的反应活性,并有效地抑制了COx的生成,从而增加了总C2(乙烯和乙腈)的选择性.在550℃时,Sb2O3负载质量分数为5%的样品上的乙烷转化率和乙腈选择性分别为68.4%和51.6％,乙腈收率达到了35.3％.这是迄今为止乙腈收率最高的氨氧化反应结果.

Abstract:

The catalytic ammoxidation of ethane with oxygen and ammonia was investigated over a series Sb2O3 promoted ion-exchanged Co-ZSM-5 zeolites(Sb2O3/Co-ZSM-5).The introduction of appropriate amount of Sb2O3can considerably improve the conversion of ethane,suppress the formation of COx,and increase the total C2 selectivity to acetonitrile and ethylene.Among them,the sample with 5% Sb2O3loading(in mass fraction) shows a 68.4% ethane conversion at 550 ℃,a 51.6% selectivity to acetonitrile and a 31.7% selectivity to ethylene,and a 35.3% yield of acetonitrile were obtained,which is to our knowledge the highest ever reported for the direct ammoxidation of ethane.
