FIELD: chemistry.
SUBSTANCE: invention relates to distributors of fluidised materials, in particular to distributors of used catalysts used in cracking operations with fluidised catalyst, as well as to a system and method associated therewith. Powder-like materials distributor system comprises a reservoir and a powder material distributor located inside the reservoir and containing a spent catalyst with lateral inlet distribution system comprising a cylindrical reservoir of powder materials, a gas line, powder materials transfer line, having hydraulic connection with cylindrical reservoir of powder materials and gas line, central pipeline, distributor, having hydraulic connection with central pipeline and powder materials transportation line, wherein the distributor comprises one, two, three, four, five, six, seven, eight, nine, ten, eleven or twelve branch pipes and each of the branched pipelines comprises slots arranged on the lower side of the branched pipelines, and a gas distribution system located inside the inner chamber of the reservoir. Method of distributing pseudo-liquefied materials involves providing a system of distributor of powdery materials and passing powdered materials and gas through a distributor of powdery materials into a reservoir.
EFFECT: invention provides uniform distribution of spent catalyst inside regenerator.
