Mathematical Models for Direct Reaction of Methyl Chloride With Silicon in Fluidized Bed Reactor

الملخص

Methyl chlorosilanes are important raw materials for the production of polyalkylsiloxanes, the basic ingredient of silicone oils and silicone rubbers. One of the main methods for the commercial production of methyl chlorosilanes, known as direct process, involves a reaction between elemental silicon (Si) and methyl chloride (MeCl). The principal product is dimethyldichlorosilane, which is used to form the polydimethylsiloranes. The aim of this work is to predict a mathematical models in which it shows the behavior of the reaction. We predict four models, these models take in consideration the reaction kinetic the physical, chemical, and design equation of fluidized bed reactor. The equations shows the conversion of MeCl as function of temperature and time, conversion of silicone as function of time, particle diameter as function of time. We have compared the result from these models with practical result from international papers. And it shows good agreement.
