ZEOLITE CATALYST FOR ISOPARAFFIN-OLEFIN ALKYLATION AND ALKYLATION METHOD USING THE CATALYST

摘要

PROBLEM TO BE SOLVED: To provide a zeolite catalyst for isoparaffin-olefin alkylation which is excellent in selectivity of gasoline fraction hydrocarbons while suppressing the generation of high-boiling-point fractions and carbonaceous substances and can keep the selectivity high over a long period.;SOLUTION: The zeolite catalyst for isoparaffin-olefin alkylation contains fine zeolite particles being particulate zeolite with an average particle size of 0.1-1.0 μm and/or platy zeolite with an average thickness of 0.01-0.5 μm. The zeolite is of a faujasite type and contains at least one kind of lanthanoide group element in a quantity of 5-30 wt.% in terms of oxide. The catalyst is composed of the above-mentioned zeolite and a binder and is a spherical molded article having an average particle size of 0.3-5 mm or a platy molded article having an average thickness of 0.01-5 mm.;COPYRIGHT: (C)2005,JPO&NCIPI
