Processo para oxidação direta parcial catalisada heterogeneamente de propano e/ou de isobutano a pelo menos um dos produtos alvo, ácido acrílico, ácido metacrílico

摘要

Disclosed is a method for the heterogeneously catalyzed partial direct oxidation of propane and/or isobutane. According to said method, target product is separated from the product gas mixture obtained in the reaction stage in a reprocessing stage, the remaining product gas mixture is divided into two partial quantities having the same composition, one partial quantity is redirected into the reaction stage while the other partial quantity is discharged, and both the reaction stage and the reprocessing stage are operated at an increased pressure.
