Abstract

Prosess og utstyr for å bringe silisiumtetraklorid til å reagere med flytende sink for å fremstille silisium og sinkklorid, der reaksjonen finner sted i en reaktor (1). Silisiumtetrakloridgass sprøytes kontinuerlig inn gjennom en eller flere dyser (7) til en strøm av smeltet sink (5) i en reaksjonssone (2) av reaktoren der temperaturen er over smeltepunktet til sink (>419 ºC) og under koketemperaturen til sinkklorid ved 1 atmosfæres trykk (732 ºC). Reaksjonsproduktene, silisium og sinkklorid, samles i en separasjonssone (3) som de kan tas ut fra. Med den foreliggende nye prosessen og utstyret kan silisium med høy renhet produseres effektivt og billig.Process and equipment for reacting silicon tetrachloride with liquid zinc to produce silicon and zinc chloride, where the reaction takes place in a reactor (1). Silicon tetrachloride gas is continuously injected through one or more nozzles (7) into a stream of molten zinc (5) in a reaction zone (2) of the reactor where the temperature is above the melting point of zinc (> 419 ° C) and below the boiling temperature to zinc chloride at 1 atmospheric pressure. (732 ºC). The reaction products, silicon and zinc chloride, are collected in a separation zone (3) from which they can be removed. With the present new process and equipment, high purity silicon can be produced efficiently and cheaply.
