<p>PURPOSE:To obtain an alpha-alumina base catalyst carrier of superior mechanical properties and purification performance by adding a magnesium compound to activated alumina thereby making the same into spinel structure at the time of calcining the activated alumina to alpha-alumina. CONSTITUTION:A magnesium compound such as MgO or MgCO3 is added to activated alumina as an alpha-alumina base catalyst carrier for purification of waste gases, and the mixture is heated to have 10-40wt% spinel. Then, this catalyst carrier is improved of mechanical properties such as abrasion resistance and crushing resistance and the superior carrier having improved activity which will not degrade is obtained.</p> |
