The invention relates to a metal load type catalyst and a preparation method therefor, and an application of the catalyst in preparation of glycerol carbonate, and relates to the fine chemical engineering field. The catalyst disclosed by the invention is a multi-metal load type catalyst; by taking Al<2>O<3>-based porous ceramic as a carrier, active ingredients are loaded through an impregnation way; and then the load type catalyst is prepared by a high-temperature roasting way. By virtue of the catalyst, glycerol carbonate is synthesized by taking glycerol and urea as raw materials; the glycerol carbonate is purified by a molecular distillation system; when the feed rate is 0.5-5ml/min, the vacuum degree is 1-15Pa, the evaporator temperature is 100-200 DEG C and the condenser temperature is minus 10 to 50 DEG C, a glycerol carbonate product is good in separation effect, high in yield and high in purity; and the yield of the obtained glycerol carbonate is greater than 95%, and the purity of the glycerol carbonate is not lower than 99% and can be as high as 99.89%.
