Advance of catalysts for increasing propylene production in FCC

The advancee of technique and catalyst for increasing propylene production of FCC in China and abroad were reviewed.As well as the propylene yield of each technique,the effection of key catalyst and the modification technique of shape selectivity molecular sieve were analyzed and compared respectively.The results showed that deep catalytic cracking was the super advanced technique for increasing propylene in the world at present.It was also proposed that researching and designing other novel catalyst for increasing propylene production was the important work in the future.
