    Abstract: ISOTHERMAL PROCESS FOR THE DEHYDROGENATION OF ALKANES Abstract Isothermal process for the dehydrogenation of alkanes to the corresponding alkenes over a catalyst bed comprising a dehydrogenation-active catalyst, wherein the catalyst bed comprises a catalytically inactive, inert diluent material. The catalytically inactive, inert diluent material is preferably selected from the group consisting of the oxides of the elements of main groups II, ill and IV, transition groups ill and IV and V, mixtures thereof and nitrides and carbides of elements of main groups ill and IV and preferably has a BET surface area of

    Abstract: The disclosure relates to a process for preparing butadiene. The process involves nonoxidatively catalytically dehydrogenating butane to obtain a product gas stream containing butane, 1-butene, 2-butene, butadiene, hydrogen and secondary constituents. The 1-butene and 2-butene of the product gas stream is then oxidatively dehydrogenated to give a second gas stream containing butane,2-butene, butadiene, hydrogen, steam and secondary constituents. Next, the butane,2-butene and butadiene are separated from the second gas stream and the butane and 2-butene are then separated from the butadiene product. The butane and 2-butene are then recycled into the nonoxidative catalytic dehydrogenating zone.
