Embodiment 1

[0035] (1) 10 kg REHY molecular sieve (RE 2 o 3 Content 9.0% by weight, Na 2 O content 4.5% by weight, silicon-alumina ratio is 5.2, Qilu Petrochemical Company Catalyst Factory production, the same below) joins 70 kilograms of phosphorus-containing 0.4 weight % (in P 2 o 5 meter) ammonium phosphate solution, the temperature was raised to 60°C, stirred for 2 hours, and filtered. After the molecular sieve filter cake was dried at 120°C, it was calcined at 600°C in air for 0.5 hours.

[0036] (2) 9.16 kg of kaolin with a solid content of 78% was added into 20.8 kg of decationized water for beating evenly.

[0037] (3) 2.76 kilograms of pseudo-boehmite with a solid content of 60% are beaten with 11 kilograms of decationized water, after stirring for 20 minutes, add 365ml of 36% hydrochloric acid (the specific gravity is 1.185 grams / ml) after acidifying for 120 minutes, slowly Add 8% SiO 2 Content modulus is 4.88 kilograms of water glass solutions of 3.1, stirs about 30 minut...

Embodiment 2

Abstract

A cracking catalyst for petroleum hydrocarbon is proportionally prepared from clay, aluminum oxide prepared from alpha-AlO(OH), Y-type molecular sieve containing RE and P and silicon oxide. Its advantages are strong power to convert heavy oil and high output rate of diesel oil.

Description

technical field [0001] The present invention relates to a petroleum hydrocarbon cracking catalyst and a preparation method thereof, and more particularly relates to a silicon-aluminum matrix petroleum hydrocarbon cracking catalyst and a preparation method thereof. Background technique [0002] Since the 1980s, catalytic cracking has developed from wax oil cracking to residual oil cracking, and the amount of slag added has increased year by year. Since the residual oil contains macromolecular compounds such as colloidal asphaltenes, it cannot enter the molecular sieve channels of the catalyst for cracking reactions. Seriously affect the reaction performance of the catalyst. [0003] In recent years, with the increasingly stringent environmental protection requirements, gasoline standards have also undergone major adjustments, and the olefin content in gasoline is used as the quality index of gasoline. In 1999, China's State Environmental Protection...
