Jochem Hahn

A plant for preparing monosilane (SiH) by catalytic disproportionation of trichlorosilane (SiHCl) includes a reaction column having a feed line for trichlorosilane and a discharge line for silicon tetrachloride (SiCl4) formed, and at least one condenser via which monosilane produced can be discharged from the reaction column, wherein the reaction column has at least two reactive/distillative reaction regions operated at different temperatures and containing different catalytically active solids, at least one of the reaction regions containing a catalytically active solid based on vinylpyridine, and at least one of the reaction regions containing a catalytically active solid based on styrene.

Method and system for producing monosilane

A process for preparing high-purity silicon by thermal decomposition of a silicon compound includes decomposing the silicon compound by mixing with a carrier gas at a temperature at which the silicon compound is thermally decomposed.
