The invention discloses an aromatic hydrogenation catalyst. The aromatic hydrogenation catalyst comprises a silicon-aluminum carrier and a hydrogenation active metal component loaded on the silicon-aluminum carrier, and is characterized in that the proportion of pyridine infrared B acid to L acid of the silicon-aluminum carrier, which is measured at the temperature of 200 DEG C, is 0.085-0.1. The invention further provides a preparation method of the aromatic hydrogenation catalyst and the aromatic hydrogenation catalyst obtained by the method. In addition, the invention further provides an aromatic hydrogenation catalytic method utilizing the aromatic hydrogenation catalyst. The aromatic hydrogenation catalyst provided by the invention has the advantages of obvious mesoporous property and centralized pore distribution, simultaneously contains centers of B acid and L acid, and obviously increases the proportion of the B acid to the L acid in comparison with the prior art. Data of an embodiment shows that compared with the prior art, namely a contrast example 1, the hydrogenation activity of the aromatic hydrogenation catalyst disclosed by the invention can be increased by up to 20%.
