    Abstract: A dehydrogenation process, where a hydrocarbon feed is dehydrogenated in a dehydrogenation zone and then oxidatively reheated by the combustion of hydrogen in an oxidation zone containing an oxidation catalyst, is improved by using a stream of dilution steam as an educing fluid to draw oxygen into contact with the effluent from the dehydrogenation zone ahead of the oxidation zone. A stream of dilution steam is often combined with the dehydrogenation zone effluent in order to control the oxygen concentration ahead of the oxidation zone and to lower the hydrogen partial pressure. Educing the oxygen-containing gas for the oxidation zone into the process by using the dilution steam an an educing fluid eliminates the need for compression of the oxygen-containing gas and prevents oxygen from contacting the dehydrogenation zone effluent before the dilution steam is admixed therewith. This process is particularly beneficial in the dehydrogenation of ethylbenzene to produce styrene.

    Abstract: An apparatus for carrying out a catalytic chemical reaction in the presence of a granular catalyst under conditions such that both the reactants and the reaction product are gaseous at the temperature and pressure of the reaction. According to the present invention, a vertically extending, annular, intercylinder space, defined between a cylindrical outer catalyst retainer and a cylinder inner catalyst retainer, is divided by radially extending vertical partition walls into a plurality of chambers. Heat-exchanging tubes are disposed vertically in at least one of the chambers. A granular catalyst is packed in at least two of said chambers to form at least two reaction chambers. A feed gas is caused to flow successively and in radial directions through these reaction chambers. Since the invention reactor achieves an improved linear gas flow velocity and a greater overall heat-transfer coefficient, the reactor of the invention requires fewer heat-exchanging tubes and can thus be made smaller. The optimum temperature distribution for the reaction can be attained in each reaction chamber.
