High productivity process to produce n-butane maladministration

摘要

The process of high productivity to produce both malu00e9ico of N - butane for the production of malu00e9ico anhydride by catalytic oxidation of n-butane in the vapor phase using oxygen or enriched air coIt means of oxidation, the reaction mixture consists of butane, oxygen and a gas exhaust recycling recovered from the stage of absorption by a solvent to carbon malu00e9ico produced in the reaction.In this process, the concentrations of carbon monoxide and carbon dioxide in the mixture from the reactor is maintained at optimum levels for the implementation of the reaction in a catalyst V.P.O.Appropriate, and the feed gases for recycling, in addition to butane and oxygen, from a gas stream rich in carbon dioxide.
