VERFAHREN ZUM KATALYTISCHEN KRACKEN EINER KOHLENWASSERSTOFFCHARGE IM WIRBELBETT

摘要

A process for the catalytic cracking of a hydrocarbon charge comprises contacting the charge with a catalyst in a column (1) of a unit, separating the catalyst from the reaction effluents in a separator (10), stripping the used catalyst and regenerating said catalyst, in which pure oxygen is added (through line 31) to the stripping gas, which generally consists of steam, the stripping gas/oxygen ratio by volume ranging from 1 to 20, the proportion of oxygen thus used as make-up gas being from 1 to 50% with respect to the total amount of oxygen consumed in the unit. <IMAGE>
