The present invention discloses a method for preparing valerolactone through catalytic hydrogenation of ethyl levulinate. The method comprises: placing ethyl levulinate and different molar ratios of titanium zirconium microsphere catalysts in a device, adding isopropanol as a solvent and a hydrogen source, and carrying out a reaction for 2-10 h at a temperature of 160-200 DEG C, wherein a molar ratio of the titanium zirconium microsphere catalyst is Ti/Zr of 1:0, 8:2, 5:5, 2:8, and 0:1. According to the present invention, the catalytic activity of the method is good, the ethyl levulinate can be completely converted, the yield of the valerolactone can achieve 90.1%, the production cost is reduced by using the alcohol as the hydrogen source, and the catalytic system can be recycled more than 6 times while the catalytic efficiency is not significantly reduced.
