Study on the effect of asphalt pretreatment on the structural and electrochemical properties of porous carbon based on finite element analysis

Bitumen is a high-quality raw material for the preparation of carbon materials due to its high carbon and low ash characteristics, and its use in the preparation of supercapacitor electrode materials plays a significant role in the enhancement of the economic benefits of the entire coal chemical process.In this paper, the raw materials and experimental equipment required for this study were selected to prepare porous carbon samples under the guidance of the raw material pretreatment process.After completing the preparation of porous carbon samples, the finite element analysis software ANSYS was used to investigate the effect of bitumen pretreatment on the structure and electrochemical properties of porous carbon.With the rising air oxidation time, the peak ratio of porous carbon showed a trend of decreasing and then increasing, with specific values of 2.627, 1.958, 2.083, and 2.486, which was the same trend as that of the XRD test results, suggesting that the asphalt pretreatment has a moderating effect on the structure of porous carbon.The study in this paper further recognizes the effect of asphalt pretreatment on the structure and electrochemical properties of porous carbon, which provides a reference for research and development and innovation in materials chemistry.
