[0037] According to the preparation process of the HT-A catalyst, according to the component content ratio of the catalyst HT-B in Table 1, add aluminum chloride, nickel chloride, sodium tungstate in the reaction tank, then add 16% ammonia water to form a gel, until The pH value is 9, the gelling temperature is 80°C, aging for 3 hours after gelling, and then filtering, the filter cake is washed twice with 500mL clean water, added clean water and molybdenum trioxide, beaten and stirred evenly, filtered, the filter cake is at 70 Dry at ℃ for 7 hours, then extrude, wash with clean water twice, dry at 100℃ for 8 hours, and calcined at 550℃ for 3 hours to obtain the final catalyst HT-B. The composition and main properties are shown in Table 1.
