Abstract

Regenerating, by oxidn. a used catalyst from hydrocarbon cracking, comprises carbonisation of the coke deposits in two phases during the passage of a regenerating gas through a fluidised bed of the catalyst, in an appts. comprising a body in the tower part of which is mounted a cylinder forming with the body of an annular space. The cylinder is provided with a pipe for charging used catalyst. A column for discharging regenerated catalyst is placed in the annular space. The cylinder and the annular space are equipped with their own pipes and distributors for charging regenerating gas. A cyclone separator and a used gas outlet pipe are mounted in the upper part of the body. A vertical partition is mounted in the annular space. The first phase of the regeneration is carried out in an ascending fluidised bed of the catalyst with parallel flow of gas and catalyst, the gas flowing at a high speed. The second phase is carried out in a fluidised bed with cross flow of gas and catalyst, the gas flowing at a lower speed. The process and appts. give an increase in the depth of the regeneration of the catalyst, i.e. a redn. in the content of residual coke of the catalyst, an increase in the uniformity of regeneration of the catalyst particles and a reduced load in the cyclone.
