Embodiment 1
[0015] Use freshly boiled distilled water to prepare 1.0mol / L Ni(NO 3 ) 2 , Mg(NO 3 ) 2 , Al(NO 3 ) 3 and 0.5mol / L of Zr(NO 3 ) 4 Metal salt solution; prepare another 1.0mol / L NaOH solution and 0.5mol / L NaOH solution 2 CO 3 solution. According to the catalyst composition Ni: 5.5wt%, MgO: 51wt%, Al 2 o 3 : 9.5wt%, ZrO 2 : 34wt%, Ni, Mg, Al, Zr four kinds of nitrate solutions are made into a mixed solution, and the solution is denoted as A. A certain amount of Na was added to the beaker in advance 2 CO 3 Solution [CO 3 2- The molar weight of = 0.5 (Al 3+ +Zr 4+ ) molar weight], solution A and NaOH solution are simultaneously titrated into the beaker, the rate of addition is controlled, and the stirring is continued to keep the pH between 9 and 10. After the dropwise addition, stir and age in a constant temperature water bath at 60°C for 12 hours, wash and centrifuge until the pH is around 7, perform suction filtration, put the filter cake in an oven, and dry at...
