    • 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.

    • PROBLEM TO BE SOLVED: To inhibit easy diffusion of high boiling point hydrocarbons and coke formed in producing isoparaffin-olefin alkylates to the exterior of zeolite catalyst particles to cause poisoning of the active site of the zeolite catalyst and clogging of fine pores. SOLUTION: The alkylation of an isoparaffin-olefin mixture is performed by bringing a mixture of an isoparaffin and an olefin at a ratio (Mip/Mo) of the molar number (Mip) of the isoparaffin to that (Mo) of the olefin of 2-50 into contact with a zeolite catalyst in the presence of an organic solvent at 25 to 150°C. The organic solvent is at least one kind selelcted from an aromatic hydrocarbon, an alcohol, a polyhydric alcohol, an ester, an ether, a ketone, and a saturated hydrocarbon other than the isoparaffin. The zeolite catalyst is fine zeolite particles comprising granular zeolite having an average particle diameter of 0.1-1.0 μm and/or plate zeolite having an average thickness of 0.01-0.5 μm.
