System for promoting silane reaction generation and process by-product full recovery by using catalyst

The utility model provides a system for promoting silane reaction generation and completely recycling process byproducts by using a catalyst. According to the utility model, silane mixed gas generatedby reaction is separated from solid raw materials participating in the reaction by a newly developed and designed separation and purification system and technology; carrying out low-temperature gas-liquid separation on the silicon methane from the mixed gas according to the physical characteristics of the silicon methane; the silicon methane fractionation system is used for recovering the ammoniaraw material in the silicon methane, purifying the silicon methane and removing impurities of the silicon methane; carrying out fractionation and purification on the silicon ethane and ammonia raw materials subjected to gas-liquid separation by using a silicon ethane distillation system; according to the present utility model, the silicon ethane conversion rate is improved by using the developedunique catalyst use technol
