| description | In this paper, pyrolysis treatment was carried out with the tank bottom sludge of Liaohe Oilfield (LSOS) as the treatment object. Pyrolysis oil has the highest output of only 6% and the main components are gasoline and light diesel. Syngas which was the main form of energy recovery was mainly composed of CO/CO

, etc. Temperature is the most important factor affecting energy recovery, and high-temperature environments have a positive impact on the cracking of macromolecular hydrocarbons. Increasing the temperature had a significant effect on improving the efficiency of energy recovery, which is beneficial to the recovery of energy in the form of gaseous and liquid oil. The content of organic matter in char greatly reduced, which was reflected in the significant reduction in C/H content. Part of the S/N compounds migrated and transformed, mixed into gas and liquid oil while heavy metals were enriched in char. The thermogravimetric method was carried out for the study on the pyrolysis behavior of LSOS. Starink method, KAS method and FWO method were used to calculate the kinetic parameters. The activation energy range and the average activation energy calculated by the three methods all showed high similarity, which were 61.75–237.33 kJ·mol
