Embodiment 1
[0028] In this example, the carbon-containing chemical waste is a mixture of coke powder and heavy-phase coal tar pitch; the coke powder is coke obtained from coking coal by high-temperature dry distillation at 1000°C and then sieved. The particle size is less than 10mm, the mass fraction of fixed carbon in the coke powder is 78%, the mass fraction of ash is 14%, the mass fraction of volatile matter is 0.8%, and the mass fraction of total sulfur is 0.8%; the heavy phase coal tar pitch is produced The remaining bitumen tailings with a softening point of 78°C in the needle coke process, the coking value of the heavy phase coal tar pitch is 55%, and the mass percentage of quinoline insoluble matter is 15%.
[0029] The chemical carbon-containing waste is composed of the following components by mass percentage: heavy phase pitch 25%, coke powder 75%.
[0030] The heavy phase asphalt and coke powder are crushed and ground separately, and then uniformly mixed to obtain a mixed raw m...

[0033] In this embodiment, the carbon-containing chemical waste is a mixture of coke powder and heavy-phase coal tar pitch; the coke powder is coking dust removal ash with a particle size of less than 10mm, the mass fraction of fixed carbon in the coke powder is 76%, and the mass fraction of ash is Fraction is 17%, the mass fraction of volatile matter is 0.5%, and the mass fraction of total sulfur is 1.0%. The coking value of phase coal tar pitch is 58%, and the mass percentage of quinoline insoluble matter is 13%.
[0034] The chemical carbon-containing waste is composed of the following components by mass percentage: heavy phase pitch 35%, coke powder 65%.
[0035] The heavy phase pitch and coke powder were crushed and ground separately, and then uniformly mixed to obtain carbonized raw materials, and tar with a mass fraction of 18% and water with a mass fraction of 10% were added to the carbonized raw materials as binders, and the carbonized raw materials and viscous The b...
Embodiment 3
[0038] In this example, the carbon-containing chemical waste is a mixture of coke powder and heavy-phase coal tar pitch; the coke powder is coke obtained by high-temperature dry distillation of coking coal at 980°C and then sieved undersize and coking dedusting ash The mixture, the mixing ratio is 1:1 (the two can be mixed in any ratio in the present invention), the particle size of the coke powder is less than 10mm, the mass percentage of fixed carbon in the coke powder is 77%, the mass percentage of ash is 15%, and the volatilization The mass percentage of fen is 1.1%, and the mass percentage of total sulfur is 0.6%; the heavy phase coal tar pitch is the remaining bitumen tailings with a softening point of 92°C in the process of producing needle coke, and the coking value of the heavy phase coal tar pitch is It is 59%, and the mass percentage of quinoline insoluble matter is 19%.
[0039] The chemical carbon-containing waste is composed of the following components by mass pe...
