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