| 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 re- duced coated catalyst, thereby regenerating the second catalyst; (d) using said regenerated second catalyst in step (a).
