▎ 摘　　要

NOVELTY - A monolithic boron-doped titanium silicalite-1 (TS-1) catalyst carrier has a metal framework with interpenetrating three-dimensional pores inside, and boron-doped carbon layer grown on the metal framework. USE - Monolithic boron-doped TS-1 catalyst carrier used for preparing TS-1 catalyst (claimed) used in one-step direct oxidation method for preparing propylene oxide. ADVANTAGE - The TS-1 is capable of covering surface of the catalyst carrier in the form of micro-crystal grain to maximize catalytic performance of TS-1 and effectively eliminate internal diffusion. The TS-1 catalyst is capable of improving selectivity of the main product propylene oxide and production efficiency, and reducing selectivity of the side reaction and production cost. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: 1. preparation of the monolithic boron-doped TS-1 catalyst carrier, which involves: a. taking metal framework for cleaning and drying; b. placing in a chemical vapor deposition furnace; c. raising temperature to required temperature under protection of argon gas or nitrogen; d. switching to pure hydrogen or a mixture of hydrogen and argon or nitrogen; e. mixing the raw materials containing boron and carbon in the form of gas and inert gas, or mixed gas of hydrogen gas; f. passing into chemical vapor deposition furnace; g. heating to grow boron-doped carbon layer on the metal framework; h. lowering temperature to room temperature; 2. application of the monolithic boron-doped TS-1 catalyst carrier for preparing monolithic TS-1 catalyst, which involves: a. dispersing and covering TS-1 catalyst on the surface of the monolithic boron-doped TS-1 catalyst carrier in the form micro-crystal grain.
