Abstract

A catalyst bed system, and a dehydrogenation process using the same, including a horizontal catalyst bed having 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 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.
