Insight into reaction performance and product formation in a novel coal pyrolyzer of pilot-scale test J. Anal. Appl. Pyrol. (IF 6.0) Pub Date : 2024-03-05 Yanan Qian, Ping An, Xin Jia, Zhennan Han, Rongcheng Wu, Xiaoxing Liu, Guangwen Xu
The pyrolysis behavior of coal in a pilot-scale moving bed with internals is modeled through computational fluid dynamics (CFD) simulations. The temperature field, reaction field, volatile flow paths inside the reactor, and effects of the internal design and operating parameters on the tar yield are systematically investigated. The simulation results show that the central gas channel allows the majority

A review on the modified red mud for biomass catalytic pyrolysis: Preparation, mechanisms and perspectives J. Anal. Appl. Pyrol. (IF 6.0) Pub Date : 2024-03-02 Yanyu Yang, Peiyuan Xiao, Meng Wen, Tingting Liu, Jinzhong Yang, Shijin Dai, Youcai Zhao, Qifei Huang, Zewei Liu, Bin Li
This paper reviews the most recent developments in modified rem mud (RM) catalytic biomass pyrolysis. The preparation of modified RM and the different types of biomass pyrolysis are discussed, as well as the mechanisms of RM catalysis affecting the end products of biomass pyrolysis. The modified RM may effectively stimulate the cleavage of macromolecules during biomass pyrolysis and enhance the quality

Chemical kinetic models, reaction mechanism estimation and thermodynamic parameters for the thermochemical conversion of solid wastes: Review J. Anal. Appl. Pyrol. (IF 6.0) Pub Date : 2024-03-02 Mohamed E. Mostafa, Radi A. Alsulami, Yasmeen M. Khedr
Producing alternative new and renewable fuel sources for future energy supply from the thermochemical conversion of solid wastes became necessary due to fossil fuel depletion and the rapid increase in the world’s energy demand. These solid wastes can be treated thermally through pyrolysis, gasification, and combustion. Understanding the thermo-kinetic behaviour of these wastes based on the thermal
