FIELD: process engineering.
SUBSTANCE: invention relates to catalyst of hydraulic treatment and/or conversion of heavy hydrocarbon beds. Proposed catalyst comprises aluminium oxide-based carrier, at least, one catalytic metal or compound of catalytic metal of group VIB and/or VIII with porous structure consisting of multiple, contact agglomerates, each formed by multiple needle-like plates. Note here that plates of every agglomerate are oriented radially relative to each other and to agglomerate center. Note that aforesaid agglomerate features irregular and non-spherical shape, exists in the form of fragments produced by crushing aluminium oxide balls and is obtained in the following stages: a) granulation of the powder of active aluminium oxide that feature poorly crystallised and/or amorphous structure to produce ball-shaped agglomerates; b) curing in humid atmosphere at 60°C to 100°C. Then, balls are dried; c) screening to recover fractions of aforesaid balls; d) crushing of aforesaid fraction; e) calcination of, at least, a part of said fraction at 250°C to 900°C; f) impregnation by acid and hydrothermal treatment at 80°C to 250°C; g) drying followed by calcination at 500°C to 1100°C. Invention covers also the method of hydraulic treatment and/or conversion of heavy hydrocarbons containing metals incorporating above described catalyst.
EFFECT: improved process performances in hydraulic conversion and/or treatment of heavy hydrocarbons beds.
