A catalyst with Iarge BET Pore Volume, a High Capacity for Cracking Heavy Oils, and Resisting Coking and the preparation and use thereof

摘要

Abstract: the present invention relates to TPA for cracking hydrocarbon oils Hfzyaan catalyst for catalytically cracking hydrocarbon oils contains a substrate alumina containing a molecular molecular sieve where It is characterized by that the pore distribution Llmhfz pore distribution of catalyst ranged from 5 to 70 of the nano pores of less than 2 m, and 5 to 70% the pores that ranged from 2 to 4, nano meterFrom February to 10% of the pores ranging from 4 to 6 nano meter; 20 to 80% pores ranging from 6 to 20 nano. M, and from February to the 40% of the pores ranging from 20 to 100, nano meter The size of the pores pore volume pores not larger than about 100 nano meters.The Llmhfz BET method in accordance with the present invention, large pore volume, and the great potential for cracking heavy oil cracking heavy oils and great resistance to coke formation resisting coking.
