“…The main components of FeRS are Fe, Fe 2 O 3 , FeO, and trace elements, such as Ca, Si, Mg, Na, Zn, and Pb [ 9 ]. Moreover, FeRS possesses a certain content oil, therefore the fluidity of FeRS is directly proportional to viscosity and oil content [ 10 ]. Furthermore, the accumulation and storage of FeRS not only occupies vast land resources, but also seriously threaten human health and the ecological environment due to its hazardous characteristics [ 11 , 12 ].…”

“…Chemical extraction with high costs and low efficiency cannot be widely applied [ 15 ]. Incineration causes secondary pollutant emissions of NO x , SO x , and heavy metals [ 10 , 23 , 24 ]. Comparatively, pyrolysis treatment under anaerobic environment can effectively eliminate the organics in FeRS with recovery of oil content.…”

Iron-rich rolling sludge (FeRS) represents a kind of typical solid waste produced in the iron and steel industry, containing a certain amount of oil and large amounts of iron-dominant minerals. Pyrolysis under anaerobic environment can effectively eliminate organics at high temperatures without oxidation of Fe. This paper firstly investigated comprehensively the pyrolysis characteristics of FeRS. The degradation of organics in FeRS mainly occurred before 400 °C. The activation energy for pyrolysis of FeRS was extremely low, ca. 5.44 kJ/mol. The effects of pyrolytic temperature, atmosphere, heating rate, and stirring on pyrolysis characteristics were conducted. Commonly, the yield of solid residues maintained around 85 wt.%, with approximately 13 wt.% oil and 2 wt.% gas. Due to the low yield of oil and gas, their further utilization remains difficult despite CO2 introduction which could upgrade their quality. The solid residues after pyrolysis exhibited porous properties with co-existence of micropores and mesopores. Combined with the high content of zero-valent iron, magnetic property, hydrophobic characteristic, and low density, the solid residues could be further utilized for water pollution control and soil remediation. Moreover, the solid residues were suitable for sintering to recover valuable iron resources. However, the solid residues also contained certain heavy metals, such as Cd, Cr, Cu, Ni, Pb, and Zn, which might cause secondary pollution during their utilization. In particular, the toxic Cr possessed high content, which should be treated with detoxification and removal. This paper provides fundamental information for pyrolysis of FeRS and utilization of solid residues.

This study examines the specific effect of Tween 80 on the conversion of anthracene (ANT) in laccase medium system regarding surfactant chemical changes and mechanism. The conversion rate and degradation products of ANT were investigated in different concentrations of Tween 80 solution. Between Tween 80 concentration 0–40 critical micelle concentrations (CMC), the kinetic parameter-k (h−1) and corresponding half-life T1/2 decreased with increasing concentration. When Tween 80 was above 20 CMC the laccase-medium system converted > 95% of ANT to anthraquinone within 12 h. During the entire enzymatic reaction, the laccase activity in the system increased with increasing Tween 80 concentration. Combined with GC/MS analysis of the product, it was speculated that hydrogens belonging to the ether-oxygen bond and carbon–carbon double bond α-CH of Tween 80, were removed by the laccase-media system, promoting its degradation. Additionally, enhanced activity caused by oxygen free radicals (ROS) such as RO• and ROO•, continuously oxidized Tween 80, which in turn produced free radicals while converting ANT. This study provides new theoretical support toward the application of surfactants in the elimination of polycyclic aromatic hydrocarbons.

Plastic wastes form 18.46 % of total municipal solid wastes in 2018 around the world. Heavy hydrocarbons occur as the waste of refinery processes. In this study co-pyrolysis of waste polystyrene foam (PS) and heavy aromatic waste (HAW) which can be accepted as a derivative of an oily sludge was carried out for the first time in literature. It was aimed to investigate the effect of temperature (420, 450, 480 ⁰C) and mixing ratio (1/5, 3/5, 1/1) on liquid product yield and compound distribution in the pyrolytic liquids. Whole experiments were done in semi-batch reactor configuration under nitrogen atmosphere. Gas chromatography-Mass spectrometry (GC-MS) was utilized to analyze the pyrolytic liquids. At 480 ⁰C it was obtained maximum liquid yield was 87.24 % in 1/5 HAW/PS feedstock ratio. Compared to pure PS pyrolysis, it was achieved relatively low styrene, toluene yield. However, yields of ethylbenzene and cumene increased with HAW added to the feed. Naphthalene was not detected in the liquid of PS pyrolysis. Maximum naphthalene yield was taken as 12.71% at 480 ⁰C with a 1/5 HAW/PS feedstock ratio.
