Description

technical field

[0001] The invention belongs to the technical field of petroleum production, and in particular relates to a heavy oil catalytic device used in petroleum production. Background technique

[0002] The riser length of a conventional catalytic cracking unit is 35-45 meters, and the oil-gas reaction time is 3-4 seconds. Modern molecular sieve catalysts are highly active, and can usually crack macromolecular raw materials into light diesel oil and gasoline components in a very short period of time. If the reaction time is too long, the light diesel oil components will be further cracked to produce LPG, dry gas and coke, especially Excessively high yields of dry gas and coke will directly lead to a decrease in the yield of light oil, and reducing the yield of dry gas and coke is one of the ultimate goals of process optimization. For the current catalytic cracking unit, due to the structure of the reactor, the length of the riser is 35-45 meters, and the oil-gas rea...
