Abstract

PURPOSE: To prevent the occurrence of bogging in regenerating tower by a procedure which coke-adhered catalyst containing iron is supplied to a specific area at the lower part of fluidized layer and gas containing oxygen in an amount not enough to completely burn coke is burned under a fluidized condition.
CONSTITUTION: In obtaining light oil and hydrogen by the draking of a heavy hydrocarbon, coke-adhered catalyst containing 30W60wt% iron is fluidized by a gas, e.g., air containing oxygen in an amount not enough to completely burn the coke in an area where the position of the delivery tube 5 through the catalyst is sent from a cracking tower to the regenerating tower 6 is in the range of l=L×(0W0.3) from the bottom of a fluidized layer on the basis of the height L of the fluidized layer of the regenerating tower 6, where the coke is burned under a reductive condition and also the ion present in the catalyst is reduced. Thus, in case a comparatively low- temperature of catalyst is supplied to an area where a bogging phenomenon is easy to occur, the occurrence of the bogging can be effectively prevented by lowering the temperature at the lower part of the fluidized layer.
