Title:
SPHERICAL TITANIUM SILICALITE MOLECULAR SIEVE CATALYST AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2022/142710
Kind Code:
A1
Abstract:
Disclosed are a spherical titanium silicalite molecular sieve catalyst and a preparation method therefor. The spherical titanium silicalite molecular sieve catalyst has the following composition: xTiO2·(1-x)SiO2/yMPO4, wherein x is equal to 0.0005-0.04, y is equal to 0.005-0.20, M is a metal element selected from alkaline earth metals, transition metals or combinations of two or more thereof. The spherical titanium silicalite molecular sieve catalyst is prepared by the following method: (i) providing titanium silicalite molecular sieve raw powder with the composition of xTiO2·(1-x)SiO2, wherein x is equal to 0.0005-0.04, and y is equal to 0.005-0.20; (ii) mixing silica sol, an organic template agent and phosphate in proportion to obtain an adhesive; and (iii) mixing the adhesive with the titanium silicalite molecular sieve raw powder, and carrying out spray-drying molding and firing to obtain the titanium silicalite molecular sieve catalyst.
