Abstract

This invention discloses a Ga-ZSM-5@Silicate-1 composite, its preparation method, applications, and a hydrogenation catalyst and hydroretrograding method. The composite comprises a Ga-ZSM-5 heteroatom molecular sieve and a Silicate-1 layer coating the Ga-ZSM-5 heteroatom molecular sieve, and the composite has a plate-like morphology. The composite is particularly suitable as a hydrogenation component, especially as a cracking component in a diesel hydroretrograding hydrocracking catalyst; moreover, the preparation method of the composite is simple and easy to operate.
