METHOD FOR PREPARING CATALYSTS OF HYDROGENATION PROCESSES TO OXIDATIVE REGENERATION Russian patent published in 2019 - IPC B01J38/62 B01J38/52 B01J38/56 C10G45/08 B01J23/94

Abstract RU 2691078 C2

FIELD: technological processes.

SUBSTANCE: invention relates to a method of preparing hydrotreating catalysts for oxidative regeneration by treating a passivated sulphide catalyst containing NiO, V₂O₅, Fe₃O₄, mixture of butyl-cellosolve and nefras, in which a complexing agent selected from oxalic, tartaric or citric acid is dissolved. Invention also relates to a method of regenerating a complexing agent solution obtained after carrying out a method of treating a passivated sulphide catalyst.

EFFECT: technical result is higher catalytic activity.
