CATALYST FOR CONVERSION OF CARBON MONOXIDE AND ITS PRODUCTION

摘要

PURPOSE:To improve activity of a catalyst in low temp. and to improve the activity holding ability of the catalyst by allowing an aq. soln. mixed a water-soluble Cu salt with a water-soluble Mn salt in the almost equimolar ratio to react with an equivalent or more amt. of an aq. alkali hydroxide soln. to the total amt. of the water-soluble salts at 60-550 deg.C. CONSTITUTION:The catalyst for conversion of carbon monoxide expressed in the formula of CuMnO2 is produced by allowing the aq. soln. mixed with water-soluble Cu salt with the water-soluble Mn salt in the almost equimolar ratio to cause hydrothermal reaction in the equivalent or more amt. of the aq. alkali hydroxide soln. to the total amt. of the water-soluble salts at 60-550 deg.C. The salt of Cu and Mn such as nitrate, chloride, sulfate, formate and acetate is preferable for the water-soluble salt of Cu and Mn. The water-soluble Cu salt is preferably mixed with the water-soluble Mn salt in a molar ratio of 0.8 to 1-1.1 to 1. The amt. of alkali hydroxide to be used may be an equivalent or more as the total amt. of the water-soluble salts.
