Example Embodiment
[0030] Example 1: Weigh 2.5g FeCl 3 Put it into a beaker, add 50g of water, stir well to get FeCl 3 Solution, then weigh 50g of petroleum coke with a particle size less than 0.074mm, and mix it with FeCl 3 The solution is mixed together and stirred with a magnetic stirrer for 24 hours; finally, the stirred petroleum coke is dried in a drying oven at 105°C for 12 hours to obtain a catalyst-supported petroleum coke prepared by the impregnation method. It is put into a fluidized bed gasifier for reaction, and the gasification agent uses air and water vapor. Gasifier working conditions: pressure is 0.1MPa, temperature is 700℃, mass flow ratio of water vapor to petroleum coke is 1, air to petroleum coke mass flow ratio is 2, and the time required for complete reaction of petroleum coke is shown in Table 1.
Example Embodiment
[0031] Example 2: Weigh 2.5g FeSO 4 Put it into a beaker and add 50g of water, stir well to obtain FeSO 4 Solution, then weigh 50g of petroleum coke with a particle size of less than 0.074mm, and mix it with FeSO 4 The solution is mixed together and stirred with a magnetic stirrer for 24 hours; finally, the stirred petroleum coke is dried in a drying oven at 105°C for 12 hours to obtain a catalyst-supported petroleum coke prepared by the impregnation method. It is put into a fluidized bed gasifier for reaction, and the gasification agent uses air and water vapor. Gasifier working conditions: pressure is 0.1MPa, temperature is 700℃, mass flow ratio of water vapor to petroleum coke is 1, air to petroleum coke mass flow ratio is 2, and the time required for complete reaction of petroleum coke is shown in Table 1.

[0032] Example 3: Weigh 1.25g FeSO 4 And 1.25gFeCl 3 Put it into a beaker and add 50g of water, stir well to obtain FeSO 4 And FeCl 3 Solution, then weigh 50g of petroleum coke with a particle size of less than 0.074mm, and mix it with FeSO 4 And FeCl 3 The solution is mixed together and stirred with a magnetic stirrer for 24 hours; finally, the stirred petroleum coke is dried in a drying oven at 105°C for 12 hours to obtain a catalyst-supported petroleum coke prepared by the impregnation method. It is put into a fluidized bed gasifier for reaction, and the gasification agent uses air and water vapor. Gasifier working conditions: pressure is 0.1MPa, temperature is 700℃, mass flow ratio of water vapor to petroleum coke is 1, air to petroleum coke mass flow ratio is 2, and the time required for complete reaction of petroleum coke is shown in Table 1.
