Claim 0:
1. A catalyst for hydrogenation of an aromatic compound, the catalyst comprising an active metal and a support,
wherein the support includes a compound of Formula 1 having a magnesium-based spinel structure:

MgxAl2O3+x  [Formula 1]

wherein x is from 0.125 to 0.25,
a Mg/Al molar ratio is 0.0625 to 0.125,
the active metal is comprised in an amount of 0.3 wt % to 5 wt % in the catalyst,
the active metal is ruthenium (Ru), and
ruthenium (Ru) or ruthenium oxide (RuO2) is supported on the support having the spinel structure, and
wherein the catalyst is an egg-shell type catalyst, and the egg-shell type catalyst has a pore volume of 0.95 ml/g to 1.5 ml/g and a BET surface area of 203.7 m2/g to 300 m2/g.
