Abstract
Provided is a catalyst composition for the isomerization of n-paraffin which comprises a β-zeolite having been synthesized according to a dry gel process and contains cerium, the β-zeolite being characterized in that it has an average particle diameter of 0.01˜0.1 μm and the proportion of the cerium in the β-zeolite is within the range of 0.001˜0.2 in terms of the atomic ratio of the silicon atom in the β-zeolite to the cerium atom, i.e. [Ce]/[Si] as well as a process for isomerizing n-paraffin which comprises bringing n-paraffin into contact with the catalyst composition as set forth above.
