The invention relates to a liquefied gas distillate hydrotreating method. A supported catalyst is employed; catalyst active components are selected to deposit at least one VIB non-noble metal oxide and at least one VIII non-noble metal oxide on a carrier; the catalyst has optimized catalyst surface acid distribution, and more preferably has optimized VIII / VIB metal ratio and VIII non-noble metal density of superficial area of per unit catalyst; and hydrogenation conditions suitable for the catalyst are adopted to significantly improve hydrogenation treatment effect. Compared with other methods, the method provided by the invention for treating liquefied gas distillate has advantages of high mercaptan conversion rate, high diene saturation ratio and better hydrogenation selectivity.
