    摘要: 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.

    摘要: 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.
