Title:
PREPARATION METHOD FOR PROPYLENE EPOXIDATION CATALYST, AND APPLICATION THEREOF
Document Type and Number:
WIPO Patent Application WO/2019/080514
Kind Code:
A1
Abstract:
A preparation method for a propylene epoxidation catalyst: pre-hydrolising a silicon source, adding a titanium source and reacting to form a sol, atomising the sol and then spraying into liquid ammonia for moulding, implementing reaming, and performing drying, roasting, and silanisation treatment to obtain a Ti-SiO2 composite oxide catalyst. The present catalyst can be used in the chemical process of preparing propylene oxide by epoxidation of propylene, the average propylene oxide selectivity being up to 97.5%, having prospects for industrial application.
