Abstract
The invention discloses a method for preparing a titanium silicon molecular sieve catalyst. The method comprises the following steps of: mixing titanium silicon molecular sieve powder, polymer monomer styrene, a polymer monomer multi-alkenyl compound and a pore-forming agent completely; in the presence of an initiator, performing a polymerization reaction; smashing the obtained blocky solid catalyst; adding the smashed catalyst into halohydrocarbon to swell; and performing extraction by using a solvent to obtain the formed titanium silicon molecular sieve catalyst. The titanium silicon molecular sieve catalyst prepared by the method solves the problem that the titanium silicon catalyst powder and reaction solution are difficult to separate and improves the reaction efficiency. The titanium silicon molecular sieve catalyst is applied to a catalytic reaction of alkene epoxidation of a fixed bed process and has excellent catalytic effect.
