Abstract:
1. A process for purifying a silane-containing stream, the stream comprising silane, ethylene and one or more compounds having a boiling point less than silane, the process comprising: introducing the silane-containing stream into a reactor to convert ethylene to at least one of ethylsilane and ethane and to produce an ethylene-depleted stream relative to the silane-containing stream; and introducing the ethylene-depleted stream into a light-ends distillation column to produce a silane-depleted overhead fraction and a silane-enriched bottoms fraction relative to the ethylene-depleted stream, the silane-enriched bottoms fraction comprising silane and at least one of ethylsilane and ethane.
