B.5 PRODUCTION OF MALEIC ANHYDRIDE FROM BENZENE, UNIT 600 Currently, the preferred route to maleic anhydride in the United States is via isobutene in fluidized-bed reactors. However, an alternative route via benzene may be carried out using a shell- and-tube reactor, with catalyst in the tubes and a cooling medium being circulated through the shell [1, 2]. B.5.1 Process Description A process flow diagram for the reactor section of the maleic anhydride process is shown in Figure B.5.1. Benzene is
