Example Embodiment

[0019] Example 1

[0020] Will contain 5% SiO 2 The modulus is 3.22 water glass 110.8L and contains 31.0RECl 3 / L concentration of 10% H 2 SO 4 15.9L, fully mixed into a PH=2 silica sol containing rare earth, and then with 54% kaolin slurry containing 21.3L, and 34% USY (Ultra stable Y) molecular sieve slurry containing 21.6L, mixed into a gel, spray dried into microspheres, Then wash to remove Na + , SO 4 ＝ , CL - , Dry, and become a highly active semi-synthetic hydrocarbon cracking catalyst A containing 20% ​​silica sol (including 5% rare earth) and 30% ultra-stable Y-type molecular sieve.

Example Embodiment

[0021] Example 2

[0022] This example is Reference Example 1, which is a catalyst prepared with silica sol containing no rare earths. Specific preparation process:

[0023] Will contain 5% SiO 2 The modulus is 3.22 water glass 118.5L and contains 10% H 2 SO 4 16.6L, fully mixed into a silica sol without rare earths, and then with 54% kaolin-containing slurry 21.3L, containing 34% USY molecular sieve slurry 21.6L, mixed into a gel, spray-dried into microspheres, and then washed to remove Na + , SO4 ＝ After drying, a semi-synthetic hydrocarbon cracking catalyst (reference agent) B containing 20% ​​rare earth-free conventional silica sol and 30% ultra-stable Y-type molecular sieve is obtained.

Example Embodiment

Abstract

The RE-containing Si-base semi-synthesized hydrocarbon converting catalyst features are that it is prepared with silicon sol binder containing RE salt 0.1-20 % (by REO), natural aluminum silicate clay and artificially synthesized molecular sieve. With RE activated silica, the catalyst of the present invention has high heavy oil cracking activity, high heavy metal contamination resistance, low content of olefin and S in catalytically cracked gasoline.

Description

technical field [0001] The invention belongs to hydrocarbon cracking catalysts, more specifically, a semi-synthesized hydrocarbon cracking catalyst containing rare earth silica sol. Background technique [0002] Petroleum is an irreplaceable transportation fuel, and petroleum resources are limited. Therefore, developing deep conversion of heavy oil and increasing light oil products will still be a major development strategy for the oil refining industry in the 21st century. The product yield, quality and economic indicators of the heavy oil deep conversion process are closely related to the catalyst performance. my country has done a lot of research and development on cracking catalysts for deep processing of heavy oil, among which silica sol semi-synthetic hydrocarbon cracking catalyst is prepared with silica sol as binder, natural aluminum silicate clay and synthetic molecular sieve Heavy hydrocarbon catalytic cracking catalyst. Since the silica sol has almost no catalyti...
