    摘要: An iodide compound is adsorbed and removed from an organic acid containing the iodide compound as an impurity by passing the organic acid through a packed bed of a cation-exchange resin having silver ion carried thereon at 50° C. or lower. The cation-exchange resin is a macroporous-type resin with an average particle size of 0.3 to 0.6 mm and an average pore size of 15 to 28 nm, and silver ion substitutes for 40 to 60% of the active site.

    摘要: A vinylpyridine resin that is hardly pulverized and thermally decomposed such that the degradation of the catalytic activity is suppressed while having a pore volume and a specific surface area to maintain a sufficient catalytic activity, and also a method of manufacturing the vinylpyridine resin are provided. The resin represents: a volume ratio of the pores having a diameter of 3 through 5 nm to all the pores of not less than 4% and not more than 60%; a total pore volume of not less than 0.15 cc/g and not more than 0.35 cc/g; and a specific surface area of not less than 20 m2/g and not more than 100 m2/g. The resin can be manufactured by using a poor solvent and not less than 50 wt % and not more than 90 wt % of a good solvent as porous agent.

    摘要: Active carbon catalyst for recovering and removing sulfur oxides contained in flue gas by turning them into sulfuric acid by a catalytic desulfurization reaction. Powdery active carbon and fluororesin are kneaded by shearing force before being molded to a desired profile so that the inter-particulate gaps of powdery active carbon particles are made water-repellent. Flue gas preferably flows downwardly through a tower filled with such an active carbon catalyst, which is made to show a honeycomb structure having surfaces running only in a direction parallel to the flow. The activity of the catalyst maintains an enhanced level if dilute sulfuric acid or water is introduced into the active carbon from the top of the tower to cleanse the surface of the active carbon catalyst so that the catalyst layer is prevented from being clogged and contaminated by ashes and soot contained in flue gas.
