Co-pyrolysis of waste paper and tyre: Exploration of interaction of volatiles of varied origin and the influence on product evolution J. Anal. Appl. Pyrol. (IF 6.0) Pub Date : 2024-02-07 Chao Li, Yifan Sun, Shu Zhang, Yonggui Tang, Dong Wang, Xun Hu
Waste paper and tyre are typical solid wastes with distinct composition. Their pyrolysis could generate varied volatiles that may interact with each other or with resulting char. In this study, the co-pyrolysis of waste paper and tyre was investigated at 400 and 600 ºC, with the focus on understanding the interaction of the volatiles on evolution of the products. The results show that the interaction

Pyrolysis of waste cooking oil to high-quality bio-oil: An acid-base coordination ZSM-5@CaO-SBA-15 micro-mesoporous composites catalyst J. Anal. Appl. Pyrol. (IF 6.0) Pub Date : 2024-02-03 Kehui Qi, Yao Yao, Yushuai Cheng, Rujie Shang, Guorui Li, Lu Li, Shuwei Liu, Zhanqian Song
An acid-base coordination SM-5 @CaO-SBA-15 composite with micro-mesoporous structure was prepared for the first time by using zeolite ZSM-5 as the acid source and alkaline-earth metal as base source. The composite has been investigated for its structure, acidity-basicity and catalytic activity on the pyrolysis valorization of waste cooking oil (WCO) to high-quality bio-oil. The characterization results

Fate of polymer derived SiC monolith at different high temperatures J. Anal. Appl. Pyrol. (IF 6.0) Pub Date : 2024-02-03 Rahul Anand, Kathy Lu
Monolithic polymer-derived SiC is highly desirable for high temperature applications because of its unique thermal properties in extreme conditions. The current study focuses on the formation, evolution, and stability of polymer-derived SiC at different high temperatures. SiC-based monoliths were pre-pyrolyzed at 1200 °C and then pyrolyzed at 1600 - 2500 °C in a flowing argon atmosphere. The porosity

Catalytic pyrolysis of duckweed with phosphoric acid: Pyrolysis behavior and kinetics analysis J. Anal. Appl. Pyrol. (IF 6.0) Pub Date : 2024-02-02 Youjian Zhu, Guangxin Huo, Wei Yang, Huihui Liu, Wennan Zhang, Wei Cheng, Haiping Yang, Zhiwei Wang, Yanling Jin, Hai Zhao
Duckweed (DW) has a promising potential for wastewater treatment due to its outstanding performance in the fixation of nutrient elements and heavy metals. The conversion of harvested duckweed into value-added products through pyrolysis is an attractive method for duckweed utilization as fuels or chemicals. In this work, the duckweed was prepared by deashing treatment and subsequent impregnation with

Pyrolysis characteristics analysis of cold mix asphalt mixture based on TG-FTIR-GC/MS J. Anal. Appl. Pyrol. (IF 6.0) Pub Date : 2024-02-02 Yang Li, Changjian Wang, Zuocai Wang, Binglin Zheng, Hongsheng Ma, Yin Zhang
This study aims at the pyrolytic behavior of cold mix asphalt mixture (CMAM), and addressing the existing knowledge gap related to their thermal stability in fire-risk scenarios. Based on a combined TG-FTIR-GC/MS approach, the pyrolysis behavior of CMAM was analyzed at heating rates of 10, 20, and 30 K·min. Pyrolysis kinetic parameters were calculated and the reaction mechanism function was determined

High quality oil and H2-rich gas production from municipal solid wastes through pyrolysis and catalytic reforming: Comparison of differently modified waste char-based catalysts J. Anal. Appl. Pyrol. (IF 6.0) Pub Date : 2024-02-01 Wenqi Fan, Mudassir Hussain Tahir, Dezhen Chen, Liu Hong, Lijie Yin, Haimiao Yu
Pyrolysis, a promising method for extracting energy and value-added chemicals from municipal solid waste (MSW), encounters challenges associated with generation of inferior quality oil and low-quality char byproducts. In this context, this study proposed catalytic reforming of pyrolysis volatiles derived from MSW, using MSW char (MSWC) and modified MSWC-based catalysts to produce high-quality oil containing

Interactions of oil shale and hydrogen-rich wastes during co-pyrolysis: Improvements of oil quality J. Anal. Appl. Pyrol. (IF 6.0) Pub Date : 2024-02-01 Mao Mu, Shaozhen Hou, Xiangxin Han, Shuang Wang, Xiumin Jiang
The “Carbon Peak and Carbon Neutrality” goal requires China actively explore new ways to supplement the oil supply for Chinese situation of oil shortage. Enormous oil shale reserves and large amount of waste plastics are viable feedstocks for supplementing the oil supply. However, individually pyrolyzing oil shale and waste plastic has its drawbacks, that is, the pyrolysis oil from oil shale contains
