Preparation method of catalyst for hydrotreating of fluidized bed

The invention discloses a preparation method of a catalyst for hydrotreating of a fluidized bed. The preparation method includes the following steps: (1) kneading and forming pseudo-boehmite and alkaline ammonium aluminum carbonate of a adsorption carbon precursor solution, and drying a formed product; (2) spraying the material obtained in step (1) by a solution containing carbon precursors, and drying and roasting the soaked material to obtain an alumina carrier; (3) impregnating the alumina carrier obtained in step (2) by impregnation liquid containing hydrogenation active components, and drying and roasting the alumina carrier after impregnation to obtain the catalyst for hydrotreating of the fluidized bed. The catalyst prepared by the method has higher strength and wear resistance, andis particularly applicable to the hydrotreating process of heavy-oil fluidized beds. 本发明公开了种沸腾床加氢处理催化剂的制备方法，该方法包括以下步骤：(1)将拟薄水铝石与吸附碳前体溶液的碱式碳酸铝铵混捏成型，成型物经干燥处理；(2)用含碳前体的溶液喷浸步骤(1)得到的物料，喷浸后的物料经干燥、焙烧制得氧化铝载体；(3)用含加氢活性组分的浸渍液浸渍步骤(2)得到
