[0034] Catalysts were prepared as follows:
[0035] S1, weigh a certain amount of zirconium oxychloride octahydrate (ZrOCl 2 ·8H 2 (2) and urea, respectively dissolved in distilled water, then slowly add the urea solution dropwise to the octahydrate zirconium oxychloride solution under stirring, fully stir the solution to mix evenly, then move the mixed solution to the inner lining PPL (para-position poly Benzene) in a stainless steel reaction kettle, heat up to 80°C for 2 hours, continue to heat up to 200°C for 8 hours, cool to room temperature, and wash the product repeatedly with distilled water until no Cl is detected. - and dried at 60°C for 8 hours to obtain ZrO 2 , followed by the alumina precursor pseudoboehmite, ZrO 2 Mix evenly with extrusion aid squash gum to obtain a mixture, then add distilled water to the mixture at a water-to-powder ratio of 0.6:1, knead in a kneader for 80 minutes, put it into an extruder for extrusion molding, and then dry at 15°C 6h, afte...
