Abstract
A catalyst in which X-ray diffraction intensity ratio of the crystal lattice plane spacing d-value of 0.196±0.002 nm to the crystal lattice plane spacing d-value of 0.386±0.008 nm is in a range from 7:100 to 35:100 and a process for making the catalyst to contact with ethylbenzene containing xylenes in the presence of hydrogen.
