The invention discloses a hydrogenation catalyst and a preparation method and application thereof, and belongs to the technical field of catalysts. The problems of low olefin conversion rate and low selectivity of isooctane and isododecane in the method for preparing isooctane and isododecane in the prior art are solved. The hydrogenation catalyst comprises a kneaded inert carrier and a hydrogenation active component, and the inert carrier is selected from one or more of Al2O3, SiO2, a silicon-aluminum composite oxide and an activated carbon material; the hydrogenation active component is selected from one or more of VIII group metal, IB group metal and VIB group metal. The invention also provides a preparation method of the hydrogenation catalyst and application of the hydrogenation catalyst in catalyzing diisobutylene to prepare isooctane and catalyzing triisobutylene to prepare isododecane. The hydrogenation catalyst is high in low-temperature reaction activity, high in impurity resistance, long in service
