Abstract:
1. A process for the catalytic conversion of a fluid feed mixture which is capable of ignition or explosion, wherein the fluid feed mixture is contacted with a catalyst bed retained in a reactor comprising: a feed supply chamber, an effluent discharge chamber, a catalyst bed having an upstream surface and a downstream surface which is in fluid communication with the effluent discharge chamber, and means for covering part of the upstream surface that partly confines the feed supply chamber comprising a rotable disc having an axis of rotation parallel to and excentric with respect to the central longitudinal axis of the catalyst bed, which disc has a radius which is larger than the sum of the radius of the catalyst bed and the distance between the longitudinal axis of the catalyst bed and the axis of rotation of the disc, and which disc has at least one opening excentric to the axis of rotation, wherein the feed supply chamber has, during normal operation, no zones where the fluid flow is stagnant.
