The invention provides a preparation method for a reformer feed hydrotreating catalyst. The preparation method is characterized in that 1) in terms of oxides, the catalyst comprises 20-30% of WO3, 1-5% of NiO, 0.5-3% of CoO, 0.5-3% of MgO, 0.3-3% of K2O, 3-10% of TiO2 and the balance of alumina; and is characterized by comprising the following steps of 2) mixing and kneading commercially available pseudo-boehmite powder, metatitanic acid, kali salt, a peptizing agent and an extrusion assisting agent until the materials are spectrally shaped; extruding the materials into strips; and drying and roasting the strips so as to obtain a K-Al2O3-TiO2 composite carrier; and 3) preparing a W-Ni-Co-Mg co-impregnation liquid at room temperature; impregnating the K-Al2O3-TiO2 carrier in a saturated way by using a saturated impregnation technology; and drying and roasting the carrier so as to obtain the hydrotreating catalyst.
