Abstract
The present invention relates to a catalyst for hydrogenation of an aromatic compound, which is capable of greatly reducing the inactivation of a catalyst by using a support including a magnesium-based spinel structure, and a preparation method therefor.
Claims5
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.
