Embodiment 1
[0029] Aluminum sulfate was dissolved in deionized water, formulated into a solution of 0.5 g / ml of aluminum oxide, and was placed in a 1 L of the aluminum sulfate solution, and then dripped with sodium hydroxide solution, pH is constant to 8.2. After the temperature is 60 ° C, the reaction is completed after 60 min, washed three times with deionized water, then add a quantified deionized water to obtain a solid liquid mass ratio of 10% (in alumina gauge)..
[0030] 20g Y molecular sieve (SIO 2 / Al 2 O 3 The molar ratio is 40.0, the cell constant is 15 å, the relative crystallinity is 90%), and 250 g of anhydrous ethanol, then add 250 g of anhydrous ethanol, stir well, then add 100 g of tetraethoxysilane, After continuous stirring is mixed, then a small amount of tetramethylammonium hydroxide is added to adjust the slurry pH to 9.0. In the closed autoclave, after 190 ° C aging for 20 h, the filtration was taken until the filter cake was 39%, and 11.2 g of ethylenediamine and 12...
Embodiment 2
[0032] Solly molybdate is in deionized water, formulated into MOO 3 A solution of a concentration of 0.12 g / ml, impregnated with a solution of 150 g of a molecular sieve modified alumina support, dried at 200 ° C for 3 h, and then reduced treatment, the reduction conditions were: reduction pressure was 1.5 MPa, and the reduction temperature was 500 ° C , The reduction time is 5 hours, the hydrogen flow is 200ml / min, then in N 2 The atmosphere was reduced to room temperature to obtain a catalyst precursor.
[0033] The cobalt nitrate is soluble in deionized water, and the COO content is 0.5 g / ml impregnation liquid, and 60 mL is impregnated into the catalyst precursor, and then in N 2 The atmosphere was dried at 110 ° C for 3 h, and 2 h was calcined at 300 ° C to obtain catalyst C-1.
Embodiment 3
[0035] Solly molybdate is in deionized water, formulated into MOO 3 A solution of a concentration of 0.11 g / ml, impregnated with 150 g of a molecular sieve modified alumina carrier, dried at 200 ° C for 3 h, then recovered treatment, the reduction conditions were: reduction pressure was 1.5 MPa, and the reduction temperature was 500 ° C , The reduction time is 5 hours, the hydrogen flow is 200ml / min, then in N 2 The atmosphere was reduced to room temperature to obtain a catalyst precursor.
[0036] Nitrate is dissolved in deionized water, and it is equipped with a NiO content of 0.5 g / ml impregnation liquid, and 60 mL is impregnated into the catalyst precursor, and then in N 2 The atmosphere was dried at 110 ° C for 3 h, and 2 h was calcined at 300 ° C to obtain catalyst C-2.
