- Also the pyrolysis mechanism of coal residue was analyzed, and the equations of pyrolysis mechanism and parameters of reaction kinetics were obtained.
- Keywords coal residue;pyrolysis;thermogravimetric analysis;reaction mechanism;
- The yield of humic acid of the coal residues increased with the increasing of the photooxidation time, coal residues increased.The order of the yield of humic acid of coal residues is D2>D3>D4.
- We need to replenish our stocks of coal.
- She piled on more coal before the fire go out.
- I add the coal on the flame continuously.
