  • ZERO-HEAT-BURDEN FLUIDIZED BED REACTOR FOR HYDRO-CHLORINATION OF SiCl4 and M.G.-Si
    Publication number: 20110311398
    Abstract: A fluidized bed reactor for producing chlorosilanes from silicon tetrachloride (SiCl4), metallurgical grade silicon (M.G.-Si) includes a SiCl4 feed line, a M.G.-Si feed line, a hydrogen (H2) feed line, a hydrogen chloride (HCl) feed line, a thermal sensor and an electronic controller. The thermal sensor is located within the fluidized bed reactor and communicates with the electronic controller to compare an actual temperature with a set-point temperature.
