    摘要: PROBLEM TO BE SOLVED: To provide a method for treating a leachate capable of improving the recovery rate for recovering molybdenum and/or vanadium from a waste catalyst, even when the molybdenum and vanadium are reduced in a leaching process.SOLUTION: The method for treating the leachate obtained in the leaching process of roasting the waste catalyst containing vanadium- and/or molybdenum-containing valuable metals with an alkali metal and/or an alkaline earth metal and leaching the obtained roasted product, includes a neutralization step of neutralizing the leachate obtained in the leaching step and an oxidation step of oxidizing the neutralized filtrate obtained in the neutralization step. In the leaching step, P, Al and the like can be removed in the neutralization step, even though the molybdenum and vanadium are reduced, in addition, the molybdenum and vanadium can be oxidized in the oxidation step. In solvent extraction, reduction of the extraction rate of the molybdenum and vanadium can be prevented with preventing clad generation.

    摘要: PROBLEM TO BE SOLVED: To provide easily soluble molybdenum trioxide having high solubility in a solution such as a multicomponent mixed solution.SOLUTION: When a multicomponent mixed solution is formed by dissolving the easily soluble molybdenum trioxide with at least one metal compound selected from the group consisting of an oxide, nitrate, sulfate, carbonate and inorganic composite acid chloride and/or an organic acid compound in a solvent, the multicomponent mixed solution has high clarity. Since the solubility is high, for example, when it is used as a raw material for the multicomponent mixed solution used for producing a desulfurization catalyst etc., the easily soluble molybdenum trioxide can be dissolved at a high concentration in the multicomponent mixed solution. Therefore, each component in the multicomponent mixed solution can be adjusted in a wide range, so that a solution in which each component is mixed in a prescribed ratio can simply be formed.

    摘要: PROBLEM TO BE SOLVED: To provide a method for firing a molybdenum-containing material to prepare molybdenum oxide useful as a raw material for a (meth)acrylic acid production catalyst having prolonged catalytic life.SOLUTION: The method for firing the molybdenum-containing material uses a kiln having a feeding port for the molybdenum-containing material at one end and a discharging port for the molybdenum-containing material at the other end, provided with a plurality of heating means arranged along longitudinal direction of the kiln, and directly blasting an oxygen-containing gas against the molybdenum-containing material at the feeding port side and the discharging port side in the kiln to fire the molybdenum-containing material. The feeding rate of the oxygen-containing gas at the discharging port side is not lower than the feeding rate of the oxygen-containing gas at the feeding port side, and the outputs of the multiple heating means are set to increase from the feeding port side toward the discharging port side.
