| titleOfInvention | Device and method for preparing high-purity silane through disproportionation reactive distillation of trichlorosilane |
| abstract | The invention relates to a device and a method for preparing high-purity silane through disproportionation reactive distillation of trichlorosilane. The method comprises a disproportionation reactive distillation process (A), a silicon tetrachloride absorption process (B), a fixed bed absorption process (C) and a product filling process (D). The method comprises the steps that: two-step disproportionation reaction is adopted, and the distillation separation action of a reactive distillation column is utilized to finally obtain a mixed gas of silane and dichlorosilane on a column top to be used as non-condensable gas of a condenser to be extracted, and a silicon tetrachloride product is obtained at a column bottom after reaction formation; a gaseous product which is recovered through a disproportionation reactive distillation column enters into a silicon tetrachloride absorption column, wherein the main ingredient of an absorbed gas is silane, an absorption liquid is filled into a silicon tetrachloride desorption column, the desorbed dichlorosilane is recovered on the column top, and the desorption liquid of the column reflows back to the silicon tetrachloride absorption tower; the absorbed gas is filled into a fixed bed to absorb so as to obtain a high-purity silane product; and the silane product is filled into a buffer tank under the pressurization condition. Technological equipment is simple, and the obtained silane product has high purity. |
