FEED NOZZLE ASSEMBLY FOR THE CATALYTIC CRACKING REACTOR Russian patent published in 2018 - IPC B01J8/24 B01J19/26 B05B7/04 C10G11/18 

FIELD: engines and pumps.

SUBSTANCE: invention refers to the feeder nozzle assembly for supplying gas and liquid to the reactor vessel, in particular the dispersion gas such as steam, and liquid feed to the catalytic cracking reactor. Feed nozzle assembly (1) for supplying gas and liquid to the reactor vessel comprises the outer tube (3) supplying the first liquid feed such as oil, the inner tube (2) comprising purging vents (28) supplying the dispersion gas, such as water vapor, the third tube (23) supplying the second liquid feed such as biomass, and ending with the nozzle. Catalytic cracking reactor may comprise one or more feed nozzle assemblies. Method of catalytic cracking, in which two or more hydrocarbon liquids are co-dispersed into the dispersion gas and are injected through the same feeder nozzle assembly (1) into the catalytic cracking reactor.

EFFECT: invention provides the possibility of combining the cracking of various hydrocarbon feed stocks such as oil and biomass, without the need to modify the hopper assembly of the elevator, riser or other parts of the reactor.
