Embodiment 1
[0045] Physical and chemical parameters of mesoporous carbon: 1200m 2 / g, 1.65ml / g, PZC 7.2, the most probable pore diameter is 3.8nm, and the specific surface area of pores smaller than 2nm accounts for 3% of the total specific surface area. Preparation process: Pour 10g of mesoporous carbon into an aqueous solution containing 10g of hydrogen peroxide, beat and stir, and control the temperature at 25°C. After 2 hours, filter and wash until there is no residue; slowly add 37% concentrated hydrochloric acid dropwise to the palladium chloride powder with a loading capacity of 5% at room temperature until it is completely dissolved; then place the palladium solution in a beaker , add deionized water to prepare an impregnating solution with a total volume of 10 times the pore volume of the treated carrier, adjust the pH value of the impregnating solution with hydrochloric acid to make it lower than PZC 4.0; after the impregnating palladium solution is fully mixed with the mesopo...
Embodiment 2
[0047] Physical and chemical parameters of mesoporous carbon: 1500m 2 / g, 1.65ml / g, PZC 6.8, the most probable pore diameter is 3.5nm, and the specific surface area of pores less than 2nm accounts for 5% of the total specific surface area. Preparation process: Pour 10g of mesoporous carbon into an aqueous solution containing 300g of hydrogen peroxide, beat and stir, and control the temperature at 10°C. After 5 hours, filter and wash until there is no residue; slowly add 37% concentrated hydrochloric acid dropwise to the corresponding mass of palladium chloride powder with a loading capacity of 5% at room temperature until it is completely dissolved; then place the palladium solution in a beaker , add deionized water to prepare an impregnation solution with a total volume of 10 times the pore volume of the treated carrier, adjust the pH value of the impregnation solution with hydrochloric acid to make it lower than PZC 5.0; after the impregnation palladium solution is fully m...
