(1) Acid catalyst, using the surface acidity of molecular sieve for catalytic reaction.
(2) The molecular sieve can support platinum and palladium metals to obtain a bifunctional molecular sieve catalyst with both metal catalytic function and acid catalytic function.
(3) Shape selective catalysts, because the catalytic action of molecular sieves generally occurs in the crystal space, the pore size and pore structure of molecular sieves have a great impact on the catalytic activity and selectivity. Molecular sieves have regular and uniform intragranular pores, and the pore size is close to the molecular size, so that the catalytic performance of molecular sieves changes significantly with the geometric size of reactant molecules, product molecules or reaction intermediates.
