A molded solid acid catalyst which is used in an isomerization reaction of hydrocarbons and the like, has high activity and excellentnstrength, and is easy to handle, and a process of preparing the same. This catalyst comprises a carrier comprising tetragonal zirconia andnalumina and, supported thereon, a sulfuric acid component and optionally a group 8-10nmetal component, wherein the specific surface areanof the catalyst is not less than 150 m 2 /g. The catalyst can be prepared by kneading an aluminum hydroxide, a zirconium hydroxide and ancompound containing a sulfuric acid component together, molding the mixture, firing the molding at a temperature capable of providing antetragonal zirconia, and optionally further supporting a group 8-10 metal component and conducting firing at 300 to 700 °C. |
