Fe改性V-La催化剂甲醇-乙醇合成异丁醛
Synthesis of isobutyraldehyde from methanol and ethanol over Fe-modified V-La catalysts
摘要
Abstract
Synthesis of isobutyraldehyde from methanol and ethanol over V-La and Fe modified V-La catalysts was investigated. Results show that under the same reaction conditions, in the time on stream of six hours, ethanol conversion and isobutyraldehyde selectivity decreased from 78% and 66% to 56% and 46%, respectively, for V-La catalyst, however, ethanol conversion and isobutyraldehyde selectivity kept over 80% and 74%, respectively, for the V-La-Fe catalyst, which indicates that Fe modification could markably improve the stability of V-La catalyst. The TPR and XRD results show that LaVO4 was main compound for V-La catalyst, while no LaVO4 compound was detected from the V-La-Fe catalyst. In addition, the reduction property of V and Fe were changed for the V-La-Fe.关键词
