Manufacturing Method of Perovskite-Type Catalyst for Desulfurization

摘要

The present invention relates to a method for producing perovskite catalyst used for desulfurization, and to provide a method for preparing perovskite catalyst for desulfurization based on lanthanum in order to improve the high temperature characteristics of the catalyst and to increase the desulfurization efficiency. do.;The perovskite catalyst according to the present invention for this purpose corresponds to 50 mol% at a concentration of lanthanum ion in an aqueous solution in which 10 to 30 mol% of nickel ions, 10 to 20 mol% of chromium ions and 10 to 20 mol% of cobalt ions are dissolved. Mixing the lanthanum hydroxide powder to produce a slurry, and maintaining the slurry at a pH of 9 to 10 and a temperature of 70 to 90 ° C to electrodeposit the metal (nickel, chromium, cobalt) ions to the lanthanum hydroxide powder. And, the hydroxide obtained by the electrodeposition reaction after washing with water, filtered and dried, characterized in that it comprises the step of heat treatment by heating at 1000 ~ 1150 ℃.;Perovskite, Desulfurization, Catalysts, Lanthanum
