Abstract

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.
