摘要： In a reactor for the decomposition of a silicon-containing gas, provision is made, to avoid silicon deposition on an inner wall of a reactor vessel, for at least one catalytically active mesh to be provided within a reaction chamber between at least one gas feed line and the inner wall (4). The mesh accelerates the thermal decomposition of the gas and reduces the deposition of silicon on the inner wall. Also described is a process for the preparation of silicon using the reactor according to the invention and the use in photovoltaics of the silicon prepared.

摘要： The invention provides a method for reducing bromine levels in brine solutions such as potassium chloride brine solutions. Bromide in solution is converted to hypobromite by the addition of an oxidant such as sodium hypochlorite. Hypobromite is precipitated by the addition of a metal cation such as magnesium under conditions of basic pH. The process is pH dependent such that the most efficient removal of bromine is achieved at a sodium hydroxide concentration of 90-200 mM. The pH optimum is also temperature dependent such that increased temperature lowers the optimal pH for bromide removal. The invention further provides a bromine-reduced potassium chloride product, suitable for uses in industrial applications. By the method of the invention bromine levels in a potassium chloride feed stock can be reduced by 97% or more.
摘要翻译： 本发明提供了一种降低盐水溶液如氯化钾盐水溶液中溴含量的方法。 通过加入氧化剂如次氯酸钠将溶液中的溴化物转化为次溴酸盐。 在碱性pH条件下，通过加入金属阳离子如镁，沉淀出次溴酸盐。 该方法是pH依赖性的，使得在90-200mM的氢氧化钠浓度下实现最有效的溴去除。 pH最佳值也是温度依赖性的，使得升高的温度降低溴化物去除的最佳pH。 本发明还提供一种适用于工业应用的溴还原氯化钾产品。 通过本发明的方法，氯化钾原料中的溴含量可以降低97％以上。
