CATALYST FOR HYDRODEALKYLATION OF ALKYLAROMATIC HYDROCARBONS Russian patent published in 2003 - IPC

Abstract RU 2200623 C2

FIELD: catalysts for petrochemical processes. SUBSTANCE: invention provides catalyst for hydrodealkylation of benzene-toluene-xylene fraction recovered from hydrocarbon feedstock pyrolysis condensate and hydrodealkylation of toluene. Alumina- supported catalyst contains 10-12% chromium oxide, 2-4% potassium oxide, and 1.5-3.0% boron oxide so that catalyst is promoted by potassium metaborate. EFFECT: increased catalytic activity and reduced coke formation. 2 tbl, 7 ex
