    摘要： A process for refining brass and cuprous chloride includes contacting solid cuprous chloride with molten brass scrap which converts the zinc in the brass scrap to a zinc chloride fume and which reduces the copper values in the cuprous chloride to molten elemental copper. The zinc chloride fume, containing minor quantities of cuprous chloride, is condensed and reduced by contact with aluminum scrap to convert aluminum in the scrap to an aluminum chloride fume and forming a molten zinc-copper-aluminum alloy product. If desired, the aluminum chloride fume can be oxidized with steam to yield an aluminum oxide product and by-product hydrochloric acid.

    摘要翻译： 用于精炼黄铜和氯化亚铜的方法包括将固体氯化亚铜与熔融的黄铜废料接触，熔融的黄铜废料将黄铜废料中的锌转化为氯化锌烟雾，并将氯化亚铜中的铜值降低到熔融的元素铜。 含有少量氯化亚铜的氯化锌烟雾通过与铝废料接触而被冷凝和还原，以将废料中的铝转化为氯化铝烟雾并形成熔融的锌 - 铜 - 铝合金产品。 如果需要，氯化铝烟雾可以用蒸汽氧化，得到氧化铝产物和副产物盐酸。

    摘要： Aluminum chloride gases and other gases from a processing system are directed to a cold trap including a blower connected thereto. The blower directs the gases, except for the aluminum chloride, out of the cold trap. The aluminum chloride is solidified in the trap. Means including a heater are provided to convert the solid aluminum chloride to a vapor and selectively empty the aluminum chloride out of the cold trap into another trap associated with means for chemically treating the aluminum chloride. The cold trap is then cooled and ready to receive additional aluminum chloride from the processing system.

    摘要： An improved method of producing anhydrous aluminum chloride via aluminum chloride hexahydrate is provided. In a preferred embodiment the method is incorporated into a process for producing aluminum from aluminous ores, and particularly from domestic ore sources comprising (1) acid leaching an aluminous ore to produce aluminum chloride hexahydrate (ACH); (2) calcining the ACH to a specific temperature of above about 450.degree. C. to produce highly reactive aluminous particles containing high residual chloride and low residual hydrogen levels; (3) reductively chlorinating the calcined ACH at a low temperature to produce anhydrous aluminum chloride suitable for electrolytic reduction; and (4) electrolytically reducing the anhydrous aluminum chloride in a fused salt to produce aluminum metal and chlorine which is recycled to step (3).

    摘要： Process for changing the volatile aluminum chloride complex contained in an ethylbenzene production stream into a non-volatile, aluminum chloride product of a nature such that the ethylbenzene in the stream can be separated from the aluminum chloride catalyst by flash distillation. Conversion of the volatile aluminum chloride complex to a non-volatile aluminum chloride product is accomplished by adding selected alcohols, aldehydes, or ketones to the ethylbenzene stream.
