However, tank bottom OS contains a high content of heavy fractions, which creates obstacles for pyrolysis due to the high activation energy. The incomplete cracking of macromolecules and secondary polymerization decreases the oil quality and causes coking during the operation process. This study introduced polyethylene (PE) into OS to deploy the H/Ceff ratio of feedstocks for pyrolysis. A strong interaction between OS and PE during copyrolysis could be observed from the TG/DTG curves. PE tightly participated in OS degradation, while OS also promoted PE degradation at high temperature. Apparent pits were generated in solid residues from copyrolysis, which was attributed to the uniform and violent gas release. In addition to HCN, other nitrogenous and sulphurous pollutants were inhibited. Accordingly, more gas products were attained after PE addition with more value-added compositions of alkanes and alkenes. Although the oil yield decreased after PE addition, the oil products from copyrolysis possessed higher heating values and higher contents of light fractions with short chains as well as paraffins. Consequently, copyrolysis of OS and PE significantly improved the pyrolysis process and resulted in high oil quality. 文稿 | �����APP胡清泉，哈尔滨项目年夜学 编者 | 吕 剑，中国科学院烟台海岸带研究所，FESE青年编委 审校 | 张 姣 本文内容来自FESE期刊2022年第16卷第10期颁发的Research article文章 “Co-pyrolysis of oil sludge with hydrogen-rich plastics in a vertical stirring reactor: Kinetic analysis, emissions, and products”。通信作者为天津年夜学林法伟副传授。 援用格局：Lujun Zhao, Jiaming Shao, Li Xiang, Yiping Feng, Zhihua Wang, Fawei Lin.
