The preliminary design of shell-and-tubes membrane reactor for oxidative dehydrogenation of ethylbenzene to styrene on a P-O-Ni-Mn/alumina catalyst (on an industrial scale) is presented. A one-dimensional pseudo-homogeneous model is used. The membrane is an inorganic and non-perm-selective one; nevertheless, it enables an oxygen flow high enough to ensure the progress of the reaction. The influence of different disturbances (feed composition, pressure and temperature) on the evolution of conversion of ethylbenzene and selectivity to styrene is analyzed. Membrane reactor allows achieving high selectivity to styrene and moderate conversion of ethylbenzene, keeping a low oxygen concentration on the reaction side. Styrene production overcomes the expected amount to carry out the design. [ABSTRACT FROM AUTHOR]
