摘要
通过对生产控制过程的研究分析,建立表观气速和催化剂补料系数控制的数学模型,对甲基氯硅烷合成工艺进行优化。结果表明:直接法合成甲基氯硅烷过程中,表观气速应分阶段控制,诱导期前为0.10~0.12 m/s,反应段为0.25~0.28 m/s较佳,所用三元铜(Cu-CuO-Cu_2O)催化剂的寿命为50~60 h,适宜配料比为2.0%~2.5%。
Base on analysis of the production control process, the mathematical modeling of the superficial gas velocity and the rate control of reactant feeding was established, which was optimizing the synthesis process of methyl chlorosilane. Results show that in the direct synthesis of methyl chlorosilane, the superficial gas velocity can be controlled by stages. The induction period is 0.10 -0.12 m/s at first and the reaction section is better during 0.25 - 0.28 m/s. The life-span of three-copper（ Cu-CuO-Cu2O） catalyst is generally 50 60 hours, and the appropriate compounding ratio is 2.0% -2.5%.
