Reaction system: The raw oil is injected from the lower part of the riser reactor under the physicochemical action of the atomized steam, and contacts the regenerated catalyst delivered from the regenerator to quickly undergo a cracking reaction to produce gasoline, diesel, cracked gas, etc. The incompletely reacted feedstock oil is separated by a fractionation tower and then returned to the reactor, which is called oil refining. The reaction gas and catalyst together with the catalyst are separated by the gas and solid separation equipment at the outlet of the riser reactor, and the catalyst is removed from the gas and gas by the settler and then enters the catalyst stripper. After the stripping, it passes through the standby catalyst standpipe and waits for it. The slide valve enters the regenerator. After the reaction, a catalyst that adsorbs a large amount of reaction condensate (coke) is called a spent catalyst. The spent catalyst meets the regeneration air compressed by the main fan in the regenerator, burns off the coke deposited on the spent catalyst, and obtains the so-called regenerated catalyst, passes through the regenerated catalyst standpipe and the regeneration slide valve, and then sends it to the riser reactor for circulation. use. The reacted oil and gas pass through the first and second cyclones in the settler to separate the carried catalyst dust, and then enter the separation system for oil cutting and gas separation.

Reaction system: The raw material oil, under the materialization action of atomized steam, shoots in from the lower part of the lift tube reactor, and comes into contact with the regeneration catalyst transported from the regenerator, and the cracking reaction occurs rapidly, generating gasoline, diesel fuel, cracking gas, etc. The incompletely reactive raw oil is separated by a fractionation tower and returned to the reactor, which is called a back refining. The reaction oil and gas, together with the catalyst, is separated by the gas and solid separation equipment exported by the lifting tube reactor, the catalyst is separated, the catalyst is released from the oil and gas by the depositor and then entered into the catalyst steam lifter, after the steam lift, the surviving catalyst riser and the surviving spool enter the regenerator. A catalyst that adsorbs a large number of reactive shrinks (coke) after the reaction is called a torso catalyst. The to-be-born catalyst meets the regenerative air compressed by the main fan in the regenerator, burns the coke deposited on the to-be-born catalyst, obtains the so-called regenerative catalyst by the regenerative catalyst riser, regeneration spool, and then feeds it into the lift tube reactor for recycling. After the reaction, the oil and gas in the settler after the first and second-stage cyclone separator will carry the catalyst dust separation clean, into the separation system for oil cutting and gas separation.

Reaction system: under the physicochemical action of atomizing steam, feed oil is injected from the lower part of riser reactor, and contacts with regenerated catalyst delivered from regenerator, resulting in cracking reaction rapidly, producing gasoline, diesel oil, cracking gas, etc. The raw oil that is not completely reacted is separated by fractionator and then returned to reactor, which is called re refining. The reaction oil and gas, together with the catalyst, are separated from the catalyst through the gas-solid separation equipment at the outlet of the riser reactor. The catalyst is stripped out of the oil and gas through the settler and then enters the catalyst stripper. After stripping, it enters the regenerator through the standpipe and slide valve of the spent catalyst. The catalyst with a large amount of reaction condensate (coke) adsorbed after reaction is called spent catalyst. The spent catalyst meets the regeneration air compressed by the main fan in the regenerator, burns the coke deposited on the spent catalyst, and obtains the so-called regenerated catalyst, which is sent to the riser reactor for recycling through the regenerated catalyst riser and regeneration slide valve. After the reaction, the oil and gas in the settler pass through the primary and secondary cyclone separators to separate the catalyst dust, and then enter the separation system for oil cutting and gas separation.<br>
