A CATALYST BED SYSTEM FOR AN ENDOTHERMIC CATALYTIC DEHYDROGENATION PROCESS AND AN ENDOTHERMIC DEHYDROGENATION PROCESS

摘要

The present invention relates to a catalyst bed system comprising a horizontal catalyst bed comprising a mixture of at least one catalytic material and at least one first inert material, a predetermined volume of at least one second inert material arranged upstream of the catalyst bed, wherein the volume of the reactor above the catalyst bed system is not filled by any solid material (empty space). The catalyst bed system is characterized in that the ratio of the volume of the second inert material and the volume of the reactor above the second inert material (empty space) is between 0.04 and 0.73, preferably between 0.06 and 0.3, most preferably between 0.09 and 0.2. The present invention relates also to a dehydrogenation process using this catalyst bed system.
