Maleic Anhydride is produced through an oxidation in a catalytic vapor phase of various hydrocarbons, and Benzene and C<SUB>4</SUB> Hydrocarbons are usually its feedstock in commercial production.<BR>A catalyst having vanadium oxides as an active component acts an important role in the process of oxidating hydrocarbons into Maleic Anhydride. In order to find out a catalyst having a higher selectivity against Maleic Anhydride, a study on the oxigen transfer mechanism over the surface of catalyst in the course of oxidation procedure was first carried out, and the oxidation kinetics was also developed for determing the optimum conditions for reation.<BR>Process for commercial purpose employs two types of reactor ; one being a fixed bed type and the other a fluidized bed type. In the following, comparison of these two types and characteristic features of several commercial processes for Maleic Anhydride production are also dealt with.
