The operating efficiency of reactors with a stationary catalyst bed in catalytic reforming and hydrotreating units is very much dependent on the design of the distributor device at the flow inlet to the reactor. The paper points out that distibutor devices of one particular type have been installed in most process vessels in the petroleum refining and petrochemical industry. It attempts to test the correctness of the selection of this distributed design and to improve its operating efficiency or develop recommendations for its replacement. A reactor model was used to test 4 types of distributor devices: type I was the distributor design that is widely used, and types II-IV were tested for comparison. It is recommended that the bottom baffle disk in type I distributors should be perforated to the extent of 5-8% (hole diameter 4-5 mm).
