Abstract
PURPOSE:To obtain a catalyst carrier having high purification performance and mechanical strength by adding and mixing powder of manganese oxide to and with activated alumina powder, molding this then curing and calcining the molding. CONSTITUTION:Rehydratable activated alumina powder is added and mixed with powder of 3-40wt% manganese oxide as beta-MnO2. Thence, this mixed powder is granulated to a spherical shape with a granulating machine and the granules are cured in saturated steam, and are dried then calcined, whereby the catalyst carrier is obtained. Thereby, the catalyst carrier by which the catalyst for purification of exhaust gas having sufficient purification performance and mechanical strength despite the small carrying amount of noble metals such as Pt, Ph, Pd is obtained.
