Abstract: The present invention provides a high-temperature ionic state fluidized bed compound crystallization technology and an internal reactor structure thereof. The principle of the present invention is that reaction gas is effected by a group of high-frequency external magnetic fields and forms the high-temperature gaseous ion in the first quartz vacuum tube, then forms ion deposition diffusion in the second quartz vacuum tube preheated at constant temperature. As a result, other high-temperature gaseous ions except the silicon hydride are decomposed, rapidly deposited and crystallized in the ion diffusion chamber. And the un-decomposed silicon hydride gas is directly poured into the surface of the silicon heating body of the compound fluidized bed by the static negative high-voltage quartz spray hole to decompose and crystallize, or crystallize by a way of fluid state in the arched heating quartz tube communicating with the top of two quartz reaction furnaces.

Abstract: A ‘hybrid’ TCS (Trichlorosilane)-Siemens process is provided to save electricity and initial investment cost from TCS synthesizing process and silicon tetrachloride to TCS converting process in a TCS-Siemens polysilicon plant, whose size is over 10,000 MT/YR of polysilicon. The ‘hybrid’ TCS-Siemens process of the current application is equipped with one direct chlorination FBR (Fluidized Bed Reactor) and one hydro-chlorination FBR. Three different TCS-Siemens processes are compared based on mass balance calculation. The hybrid TCS-Siemens process saves at least 78,000,000Kwhr/year of electricity from TCS generation only from a 10,000 MT/YR polysilicon plant when compared with a ‘Closed Loop TCS-Siemens Process’, which is equipped with only high-pressure, high-temperature operating hydro-chlorination FBRs.

Abstract: A method of manufacturing digestible powder that generates a hydride ion (H?) when dissolved in water is provided. A vacuum oven system that can reach 600° C. and 10?5 torr is used within this method. The method according to this current application comprises of ten to eleven steps of vacuuming, heating and hydrogen treatment of coral reef powder. By adding mixtures of magnesium, phosphorus and potassium, the maximum treating temperature and vacuum pressure is lowered. The coral reef powders treated via the ten steps emit hydrogen when dissolved in the water like powders that are treated with a mixture of natural form of magnesium, phosphorus and potassium complex. Those natural form of the magnesium, phosphorous and potassium includes (NH4)MgPO4.6H2O (struvite), MgSO4.KCl.H2O (Kainite), K2SO4.MgSO4.6H2O (Schönite), K2SO4.MgSO4.4H2O (Leonite), and K2SO4.2MgSO4 (Langbeinite).

Abstract: A fluidized bed reactor (FBR) for producing chlorosilane mixture, which has high contents of tri-chlorosilane (TCS), by hydro chlorination of metallurgical silicon (MGSI) and a method of producing high contents of TCS stably with the FBR is disclosed. A cooling jacket, which surrounds the lower reactor section, combined with inert initial charging material, which does not react with HCl during the reaction at a temperature of above 300° C. and pressure of above 5 bar, controls the extreme exothermal heat of the reaction. In addition to this, combination of an optimized gas distributor and a feeder that can feed the metallurgical silicon with accuracy of ±5% enabled to realize uniform temperature profile within the reaction zone within ±1° C. deviation at 350° C. of average reaction temperature and at 5 bar of reaction pressure. Without the initial charging material, temperature profile within the reaction zone is controlled within ±30° C.

Abstract: A fluidized bed reactor (FBR) for producing chlorosilane mixture containing trichlorosilane (TCS) concentration at least 50% from hydrogenation of special metallurgical silicon (MGSI), which has manganese concentration less than 35 ppmw, silicon tetra chloride (STC), and the method of producing high TCS content chlorosilane mixture is disclosed. The FBR according to current application has an expanded over head zone, whose inner diameter is at least twice bigger than that of the inner diameter of the lower straight zone. Temperature of the reaction bed is controlled between 300° C. to 600° C. within the mean temperature deviation of ±5 C. Reaction pressure is maintained between 3 to 10 bar. Retention time of the STC and hydrogen in the reaction bed is controlled to be shorter than 30 seconds. The FBR of the current application enables higher STY (space time yield; production rate/volume of the reactor) of TCS compared to any other current commercial STC cold converter, which hydrogenise STC to TCS.
