RFCC PROCESS WITH MAXIMIZED DIESEL YIELDS

摘要

The present invention relates to a RFCC process. More specifically, the present invention relates to a RFCC process with maximized diesel yield which comprises catalytically reacting a catalytic cracking catalyst in which zeolite has been selectively removed, with a petroleum feedstock in a reaction zone of a fluidized bed catalytic cracking unit to thereby obtain a product stream, an unreacted petroleum feedstock and a mixture of the used catalysts, and separating and collecting the product stream from the used catalyst and the unreacted petroleum feedstock.
