    • The invention provides a method of recovering a copper component or a manganese component from a cleaning agent containing copper oxide, a cleaning agent containing basic copper carbonate, a cleaning agent containing copper hydroxide, or a cleaning agent containing copper oxide and manganese oxide, the cleaning agents having been used for removing, through contact with a harmful gas, a phosphine contained as a harmful component in the harmful gas. Also, the invention provides a method of recovering a copper component or a manganese component from a cleaning agent containing basic copper carbonate, a cleaning agent containing copper hydroxide, or a cleaning agent containing copper oxide and manganese oxide, the cleaning agents having been used for removing, through contact with a harmful gas, a phosphine contained as a harmful component in the harmful gas. According to the present invention, the copper component and/or the manganese component can be effectively recovered from the cleaning agents in a recyclable form.
    • 本发明提供一种从含有氧化铜的清洗剂,含碱性碳酸铜的清洗剂,含有氢氧化铜的清洗剂或含有氧化铜和氧化锰的清洗剂中回收铜成分或锰成分的方法, 已经用于通过与有害气体接触除去在有害气体中作为有害成分含有的磷化氢的试剂。 另外,本发明提供了从含有碱性碳酸铜的清洗剂,含有氢氧化铜的清洗剂或含有氧化铜和氧化锰的清洗剂中回收铜成分或锰成分的方法,所述清洗剂已被用于 通过与有害气体的接触除去在有害气体中作为有害成分含有的磷化氢。 根据本发明,可以以可回收的形式从清洗剂中有效地回收铜成分和/或锰成分。

    • A process for preparing a catalyst composition comprising copper oxide, zinc oxide and aluminum oxide as essential ingredients and optionally containing boron oxide, which comprises(a) a step of precipitating from an aqueous solution of a water-soluble copper salt optionally containing a water-soluble boron compound the copper component, together with the boron component if it is present, using an alkaline substance selected from alkali carbonates and alkali bicarbonates as a precipitant;(b) a step of blowing carbon dioxide gas into an aqueous dispersion of a zinc compound selected from zinc oxide and zinc hydroxide optionally containing a water-soluble boron compound to convert the zinc compound to basic zinc carbonate and simultaneously precipitate the boron component if it is present; and(c) a step of calcining a mixture of the solid products obtained in steps (a) and (b) in the presence of an alumina precursor compound.The resulting catalyst is useful for synthesizing methanol from a gaseous mixture of carbon monoxide and/or carbon dioxide and hydrogen.
    • 一种制备包含氧化铜,氧化锌和氧化铝作为必要成分并任选地含有氧化硼的催化剂组合物的方法,其包括(a)从任选含有水溶性铜盐的水溶性铜盐的水溶液中沉淀出的步骤, 使用选自碱金属碳酸盐和碱金属碳酸氢盐的碱性物质作为沉淀剂,将铜组分与硼组分一起存在; (b)将任选含有水溶性硼化合物的锌化合物的锌化合物的水分散体吹入二氧化碳气体的步骤,将锌化合物转化为碱式碳酸锌,同时使硼成分沉淀 存在; 和(c)在氧化铝前体化合物的存在下煅烧步骤(a)和(b)中获得的固体产物的混合物的步骤。 所得催化剂可用于从一氧化碳和/或二氧化碳和氢气的气体混合物合成甲醇。
