The present invention relates to a method of catalyzing etherification, esterification, hydration, ether cleavage, isomerization alkylation, or other reactions which are catalyzable with an acid or molecular sieve catalyst. Said reactions are conducted using a novel, dual functional catalyst prepared with active components and a small amount of binder, wherein said dual functional catalyst comprises cylindrical pellets which are molded such that a cross-section or each pellet has a window lattice shape with external teeth, or a star shape with inner spokes.

[ What is claimed is:] [1.]1. A method of catalyzing etherification, esterification, hydration, ether cleavage, isomerization, alkylation, or other reactions which are catalyzable with an acid or molecular sieve catalyst comprising conducting said reaction using a dual functional catalyst prepared with active components and a small amount of binder, wherein said dual functional catalyst comprising cylindrical pellets which are moulded such that a cross-section of each pellet has a window-lattice shape with external teeth or a star shape with inner spokes, wherein in said window-lattice shape, the distance (b) between two opposite sides in each cell is within the range of 2-8 mm, the thickness of the rib (a) is within the range of 1-6 mm, and wherein in said star shape with inner spokes, the number of spokes is 2-20, the thickness of the rib (a) is within the range of 1-6 mm, and wherein the catalyst is simultaneously and efficiently capable of performing catalysis and fractionation functions when it is directly and randomly loaded into a reaction section of catalytic distillation equipment.
