| 摘要 |
The present invention relates to a catalyst bed system comprising a horizontal catalyst bed as a mixture of catalytic material and a first inert material for use in an adiabatic non-oxidative dehydrogenation process, wherein opt. a reduction gas is fed for reducing the catalytic material, a heat stream having a first temperature T1 for heating and/or regenerating the catalytic material is fed, a hydrocarbon stream having a second temperature T2 is fed, wherein T1 > T2. This system is characterized by a layer of a second inert material being arranged upstream of the catalyst bed, wherein the thickness D of the layer of the second inert material and/or the second inert material is chosen such that an almost constant temperature T3 at the interface of the second inert material and the catalyst bed is obtained being T1 > T3 > T2. The present invention relates also to a dehydrogenation process using this catalyst bed system. |
