Hydrofining catalyst and preparation method thereof

The invention relates to the field of hydrofining catalysts, and discloses a hydrofining catalyst and a preparation method thereof. The method comprises the following steps: 1) sequentially carrying out first drying, pre-roasting and first roasting on a carrier wet strip subjected to extrusion molding to obtain a catalyst carrier; (2) carrying out dipping treatment on the catalyst carrier prepared in the step (1); and (3) sequentially carrying out second drying and second roasting on the catalyst carrier subjected to dipping treatment in the step (2). Wherein the first drying condition comprises the steps that drying is conducted for 10 min to 20 min at the temperature of 40 DEG C to 70 DEG C, drying is conducted for 15 min to 25 min at the temperature of 50 DEG C to 80 DEG C, drying is conducted for 20 min to 30 min at the temperature of 60 DEG C to 90 DEG C, drying is conducted for 20 min to 30 min at the temperature of 70 DEG C to 100 DEG C, drying is conducted for 30 min to 40 min at ...
