Abstract

The vibration fluidizing density grading device for granular catalyst includes one inclined sieve plate, motor connected to the sieve plate via vibrating link rod and transmitting part, sealing hood on the sieve plate, induced draft fan connected to the sealing hood via induced draft pipeline, and feeding bin over the sieve plate with bottom pipe connected to the sealing hood via the induced draft pipeline. After the motor and the induced draft fan are on, the catalyst to be graded and fed via the feeding bin is fluidized on the vibrating sieve plate so that catalyst grains with high carbon content is exhausted from the upper end while catalyst grains with low carbon content is exhausted from the lower end. The present invention can realize grading of granular catalyst with density difference as low as 3%, and the low carbon content catalyst with average carbon content of 1.5-3.5 5 is recovered in the recovering rate of 90-95 vol%.

Description

technical field [0001] The present invention relates to a granular catalyst density classification device, in particular to a platinum reforming granular catalyst density classification device. Background technique [0002] The continuous catalyst regeneration (CCR) platinum reformer processes naphtha to produce high-octane gasoline blending components and aromatics for petrochemical utilization. The reaction is carried out in a moving bed reactor equipped with platinum-containing catalyst (granular). During the operation of the device, the catalyst can be either added to the reactor or unloaded from the reactor. Because the catalyst is continuously circulated in the reactor, carbon deposition will occur on the inner and outer surfaces of the catalyst, and in general, the amount of carbon deposition is 5%. [0003] In the above reaction process, a small part of the platinum catalyst does not fully circulate in the reactor system. This part of the catalyst that does not flow...
