The efficient use of low rank coal distillation residue is one of the important ways to achieve clean and efficient use of low rank coal. The extracted pitch was obtained by extracting the residue of rapid destructive distillation of low-rank coal using washing oil as solvents. The pyrolysis kinetics of the extracted pitch was investigated using a thermogravimetric analyzer. The activation energy of the pyrolysis reaction of the extracted pitch was calculated using Flynn-Wall-Ozawa and Kissinger-Akahi-ra-Sunose, and the kinetic parameters of the pyrolysis reaction were solved using the Satava-Sestak analysis method. The experimental results showed that G(α)=[-ln(1-α)]⁴ was the optimal mechanism function (n=4), with a reaction activation energy of 91.43 kJ/mol and a pre-exponential factor of A=4.07×10¹³. The extracted pitch was subjected to thermal conversion treatment to obtain pitch coke. The properties of the extracted pitch coke were studied using methods, e.g., polarizing microscopy, microstrength testing, Raman spectroscopy, and the corresponding peak fitting. The results showed that the extracted pitch coke was a mosaic structure mainly composed of medium particle mosaic structure (Mm) and fine particle mosaic structure (Mf). The microstrength of the pitch coke was 85.05%, the graphitic carbon microcrystal content (I_G/I_All) was 15.13%, and the amorphous carbon content (I_D3/I_All) was 12.07%. This study explores the utilization pathways of low rank coal carbonization residue from the perspective of asphalt recovery and utilization, providing a theoretical and experimental basis for achieving clean and high-value utilization of low rank coal.
