Abstract: In order to achieve the resource utilization of steel rolling oil sludge, this article studied the pyrolysis products of steel rolling oil sludge, focusing on analyzing the surface morphology, specific surface area, and pore structure of solid products at different pyrolysis temperatures, as well as analyzed the carbon structure changes of solid products based on Raman spectroscopy. Moreover, the dynamic analysis was conducted on the pyrolysis process of steel rolling oil sludge. The results show that the main components in the pyrolysis gas are H₂ and CH₄. The C-H bond from CH₄ fractured between 700 ℃ and 800 ℃, resulting in the decrease of CH₄ content and the increase of H₂ content. At a pyrolysis temperature of 800 ℃, the SEM image of the solid product show densely packed and rough micro-convexities on the surface, with a total specific surface area of 33.682 m²/g, and the highest adsorption capacity during nitrogen adsorption equilibrium. This indicates that the pore volume at this pyrolysis temperature is greater than at other temperatures. Based on the Raman spectrum analysis, in the range of 500 ℃ to 800 ℃, the value of $I_{D\mathrm{1}}$/$I_G$ gradually increases from 2.12 to 3.38 with the increasing temperature, and the amorphous carbon structure increases. In the pyrolysis process, the de-oil rate of oil sludge can be improved by properly controlling the temperature and the reaction time. The de-oil rate of oil sludge at different pyrolysis temperatures is more than 94% when the pyrolysis time is 2 hours, and the de-oil rate of oil sludge at 800 ℃ is 97.29%. Through Friedman Reich Levi method analysis, it is found that the activation energy E of the pyrolysis reaction of steel rolling oil sludge shows a trend of first increasing, then decreasing, and then increasing with the increase of conversion rate.
