METHOD OF PROCESSING HEAVY HYDROCARBON MATERIAL USING SULFUR-REDUCING ADDITIVES TO CRACKING CATALYSTS Russian patent published in 2020 - IPC C10G11/05 B01J29/06 B01J29/70 B01J21/10 B01J23/06 

FIELD: technological processes.

SUBSTANCE: invention relates to catalytic cracking of non-hydrotreated vacuum gas oil. Described is a method for catalytic cracking of non-hydrotreated vacuum gas oil, characterized in that the receiver for collecting liquid cracking products is cooled down to 0±5 °C, and the reactor is blown with argon at rate of 30 cm³/min ±5 cm³/min for 10 minutes, after which tightness of reactor is tested, in which heated up to 70±5 °C non-hydrotreated vacuum gas oil, then premixed catalytic composition consisting of cracking catalyst and 10±1 wt% of additive from catalyst weight, then temperature of reactor with catalytic composition is brought to temperature of 500±10 °C, wherein the additive used is a support based on mesoporous aluminosilicate Al-MCM-41 and aluminum oxide taken in ratio of 40/60–60/40 wt%, with Zn or Mg applied thereto in amount of 5±0.5 wt% of weight of carrier.

EFFECT: reduced amount of sulfur in non-hydrotreated vacuum gas oil cracking products.
