METHOD TO REGENERATE WASTE ACID CATALYST

摘要

FIELD: regeneration of waste acid catalysts. SUBSTANCE: method is used for regeneration of waste acid catalyst used for hydrocarbons alkylation and provides for treatment of liquid phase by reactant, that is exercised in presence of catalyst, that has at least one metal from group VIII of Periodic System applied on acid resistant carrier with usage of hydrogen as reactant. In the case oil formed as by-product during process of alkylation is used as liquid phase for treatment. EFFECT: improved waste acid catalyst regeneration process.
