Embodiment 1
[0023] Embodiment 1 catalyst preparation
[0024] Weigh 7.2 g of activated carbon and soak it overnight with 30 ml of 15% HNO3 solution, filter and wash with boiling water to remove residual acid until the pH of the system is greater than or equal to 7. The wet activated carbon was dried at room temperature, then placed in an oven at 393K to dry overnight, and then calcined in a muffle furnace at 673-773K for 5 hours, and set aside. Dissolve 18g of nickel nitrate and 0.3g of sodium silicate in an appropriate amount of water and add to the above activated carbon. Stir at room temperature for 30 min. Then the solvent was distilled off under reduced pressure, and the solid was dried in an oven at programmed temperature (300K-400K) for 10h. The dried solid was reduced with hydrogen at 650-720k for 5h, and the Ni / Na2SiO3 catalyst supported by activated carbon was obtained after reduction.
Embodiment 2
[0025] Example 2 Catalyst Preparation
[0026] Weigh 7.5 g of activated carbon and soak it overnight with 30 ml of 15% HNO3 solution, filter and wash with boiling water to remove residual acid until the pH of the system is greater than or equal to 7. The wet activated carbon was dried at room temperature, then placed in an oven at 393K to dry overnight, and then calcined in a muffle furnace at 673-773K for 5 hours, and set aside. Dissolve 25g of nickel nitrate and 0.7g of sodium silicate in an appropriate amount of water and add them to the above activated carbon. Stir at room temperature for 30 min. Then the solvent was distilled off under reduced pressure, and the solid was dried in an oven at programmed temperature (300K-400K) for 10h. The dried solid was reduced with hydrogen at 650-720k for 5h, and the Ni / Na2SiO3 catalyst supported by activated carbon was obtained after reduction.
Embodiment 3
[0027] Example 3 catalyst preparation
[0028] Weigh 7.5 g of activated carbon and soak it overnight with 30 ml of 15% HNO3 solution, filter and wash with boiling water to remove residual acid until the pH of the system is greater than or equal to 7. The wet activated carbon was air-dried at room temperature, then placed in an oven at 393K to dry overnight, and then roasted in a muffle furnace at 673K for 5 hours for later use. Dissolve 25g of nickel nitrate and 0.3g of sodium silicate in an appropriate amount of water and add them to the above activated carbon. Stir at room temperature for 30 min. Then the solvent was distilled off under reduced pressure, and the solid was dried in an oven at programmed temperature (300K-400K) for 10h. The dried solid was reduced with hydrogen at 650k for 5h, and the Ni / Na2SiO3 catalyst supported by activated carbon was obtained after reduction.
