| titleOfInvention | Catalyst for preparing trichlorosilane through silicon tetrachloride hydrogenation and preparation method thereof |
| abstract | The invention provides a catalyst for preparing trichlorosilane by hydrogenation of silicon tetrachloride and a preparation method thereof. The catalyst comprises silicon dioxide, aluminum oxide, an active component and an auxiliary agent component; based on the weight of the catalyst, the content of alumina is 10-20%, the content of silicon dioxide is 15-25%, the content of active components calculated by metal oxides is 55-75%, and the content of auxiliary components calculated by oxides is 0.5-2.0%. Adding an acidic solution into a silicon source for acidification treatment, and adding an active component, an auxiliary agent soluble salt, pseudo-boehmite, a curing agent and deionized water to prepare slurry; and (3) forming the slurry in a spray forming mode, and preparing the catalyst through post-treatment. The catalyst has good activity stability, mechanical strength and wear resistance, increases the impact and friction capacity of the catalyst with silicon powder in the use process of a fluidized bed, and avoids the phenomenon of 'running loss' in the use process of the catalyst. |
