“…As is well-known, the thermal analysis method has been widely used for characterizing thermal conversion behaviors and kinetic evaluation of waste pyrolysis. − For example, the pyrolytic behaviors and component degradation pathways of waste printed circuit boards were investigated by the thermal analysis method. , In this work, the pyrolysis process of spent LiFePO 4 batteries was analyzed by the isoconversional method, and correspondingly, the kinetic analysis was carried out for further understanding of the pyrolysis mechanism. Meanwhile, the pyrolysis products (including residue, gas, and oil) were detailedly analyzed by thermogravimetric analysis (TGA), gas chromatography-mass spectrometry (GC-MS), X-ray photoelectron spectroscopy (XPS), and scanning electron microscopy-energy dispersive spectroscopy (SEM-EDS).…”

Pyrolysis is an important way to deal with spent lithium ion batteries (LIBs). This study investigated the pyrolysis process and pyrolysis behaviors of the main components in spent LIBs. Kinetic studies on the pyrolysis process of spent LIBs were conducted using isoconversional method. The pyrolysis process of spent LIBs could be classified into four stages and the average of active energy was 85.36 kJ/mol. After the pyrolysis process, more than 96 wt % electrolyte, about 88 wt % separator, and 50 wt % poly(vinylidene difluoride) were converted into pyrolytic gas and oil, which were mainly composed of small molecular compounds, such as short-chain hydrocarbons and HF. Most of the harmful element fluorine contained in spent LIBs was converted into HF gas, which can be adsorbed by alkaline solution. Meanwhile, the pyrolysis residues of spent LIBs were mainly composed of carbon powder, fluorocarbon, hydrocarbons, active materials, copper, and aluminum foils. The active materials containing LiFePO 4 and C were not destroyed after the pyrolysis; thus, they can be reused as raw materials for producing new LIBs.

Waste tire pyrolysis has received increasing attention as a promising technology recently due to the shortage of fossil resources and the severity of environmental impact. In this study, the process of waste tire pyrolysis and upgrading to obtain high-value products was simulated by Aspen Plus. Also, based on life cycle assessment, the indexes of energy, environmental, economic, and comprehensive performance were proposed to evaluate different high-value pathways. Results demonstrate that the integrated system of waste tire pyrolysis, pyrolytic oil (TPO) refining, and pyrolytic carbon black (CBp) modification has higher energy efficiency than the independent system of TPO refining, with an improvement rate of 2.6%. Meanwhile, the resource-environmental performance of the integrated system is better. However, combined with the economic benefit, the independent system is more comprehensively beneficial, with the index of comprehensive performance (BEECR) of 0.94, which increases by 3.3% compared with the integrated system. Furthermore, the comparisons of different improved high-value paths based on the independent system as the benchmark indicate that the pathway of promoting sulfur conversion during pyrolysis to reduce the sulfur content in TPO can increase the BEECR from 0.94 to 1.064, with the growth of 13.2%. Also, the physical modification of CBp to reduce the production cost and environmental impact has better performance of BEECR, increasing by 20.2%. The final sensitivity analyses show that the combined improved high-value case established by the abovementioned two paths can achieve a favorable benefit in a wide range of crude oil and waste tire prices and the environmental tax.

Thermogravimetric and Kinetic Analysis of Co-Combustion of Waste Tires and Coal Blends

The waste tire is a fuel with the potential to partially replace coal due to the high heat value. In the present study, the combustion characteristics of the tire powders, bituminous coal, and their blends were examined using the thermogravimetric analyzer. The influence of heating rate on tire powders combustion and the burnout characteristics of their blends were studied. The increase of the heating rate caused the combustion temperature of the tire powders to become high but reduced the maximum weight loss rate. The combustion characteristics of the blends of coal and tire powders approached the combination of those of the individual sample, suggesting that the interaction effects between coal and tire powders were slight. Furthermore, the influence of different ratios on ignition characteristics, burnout temperature, and combustion effect of the blends was studied at the optimal combustion rate. The addition of tire powders improved the ignition characteristics, reduced the burnout temperature and increased the burnout rate of coal to a certain extent. An increase in the proportion of tire powders led to a decrease in the activation energy in the temperature range of 349−465 °C, whereas it caused an increase from 465 °C to burnout, which could be attributed to the fact that the volatile matter was more combustible than fixed carbon within 349−465 °C, and the combustion effect of fixed carbon in the tire powders gradually manifested in the combustion from 465 °C to burnout when the tire powders content increased.
