摘要： A continuous process for the dehydrogenation of a hydrocarbon and/or oxygenated hydrocarbon feed, comprising contacting the hydrocarbon and/or oxygenated hydrocarbon feed with a dehydrogenation catalyst at elevated temperature in a reaction zone characterized in that the catalyst is capable of retaining hydrogen and (a) is contacted with a feed to form a dehydrogenated product and hydrogen, at least some of the hydrogen formed being adsorbed by the catalyst and/or reacting therewith to reduce at least part of the catalyst; (b) the dehydrogenated product and any unadsorbed/unreacted hydrogen is removed from the reaction zone; (c) at least some of the adsorbed hydrogen is removed from the catalyst and/or at least some of the reduced catalyst is oxidized; and (d) reusing the catalyst from step (c) in step (a).

摘要： A process for the dehydrogenation of a hydrocarbon and/or oxygenated hydrocarbon feed, which process comprises the steps of(a) sequentially contacting the feed with a catalyst bed in a reaction chamber at elevated temperature, said catalyst bed comprising a first catalyst which is a dehydrogenation catalyst to produce a dehydrogenated product and hydrogen and a second catalyst capable of adsorbing and/or reacting with at least some of said hydrogen, said second catalyst having a porous coating.(b) removing the dehydrogenated product and any hydrogen which has not been adsorbed or reacted from the reaction chamber;(c) removing at least some of the adsorbed/reacted hydrogen from the coated catalyst and/or oxidising at least some of the reduced coated catalyst, thereby regenerating the second catalyst;(d) using said regenerated second catalyst in step (a).
