Preparation method of catalyst for catalytic decomposition of chlorobenzene and method for catalytic decomposition of chlorobenzene

The invention discloses a preparation method of a catalyst for catalytic decomposition of chlorobenzene and a method for catalytic decomposition of chlorobenzene. According to the invention, cobalt is used as an active component, cerium and zirconium are used as dual assistants, and the mixed cobalt-cerium-zirconium ternary component is reinforced by a special chelating agent, so that the dispersity of Co in the catalyst is improved, the specific surface area of the catalyst is increased, the reaction activity of the catalyst is improved, and the catalyst can be ensured to have better stability in a hydrogen chloride-containing atmosphere. And performing catalyst decomposition in a fixed bed device. The quality of a dry hydrogen chloride product delivered by an isocyanate device is improved, the content of chlorobenzene in the dry hydrogen chloride is reduced, and meanwhile, the operation stability of a downstream fixed bed catalytic oxidation device is greatly improved. 本发明公开了一种催化分解氯苯催化剂的制备方法及催化分解氯苯的方法。本发明以钴
