Rejuvenation of alkylation catalyst |
| abstract |
REJUVENATION OF ALKYLATION CATALYST ABSTRACT A process whereby chemically modified zeolite catalysts are treated with an organic acid to enhance their intrinsic para-selectivity in reactions involving the alkylation of aromatic compounds. The modified zeolites which may be so treated comprise those crystalline zeolites having a Constraint Index of 1 to 12, a silica to alumina mole ratio of at least 12, and having a minor proportion of the oxide from of one or more chemical elements, e.g. phosphorus and magnesium, deposited thereon. |
