摘要：

The oxidation of butane to maleic anhydride (MA) has been carried our in an inert membrane reactor, where a mesoporous membrane was used to distribute oxygen to a fixed bed of VPO catalyst. The study was carried out using relatively high butane/oxygen ratios (up to seven times higher than those currently used in industrial practice), some of which would have been in the explosive range if fed to a fixed bed reactor. The maximum MA yields obtained were respectively 17.7 and 14.2% for 5 and 10% total butane concentrations in the feed. (C) 2000 Elsevier Science B.V. All rights reserved.
