Pyrolysis of Onion Peel Waste: Investigation of Comprehensive Pyrolysis Index, Reaction Mechanism, Kinetic, and Thermodynamic Properties Using TGA Analysis

International Journal of Energy Research, Volume 2026, Issue 1, 2026.
The rising demand for onion production results in significant waste, harming the environment. Onion waste is unsuitable for animal feed and difficult to dispose of due to its strong odor and potential for phytopathogen growth. Pyrolysis is a promising method for repurposing food waste, requiring minimal infrastructure and offering rapid processing and ...

Supervised Machine Learning With Tree Ensembles and Artificial Neural Networks for Kinetic Modeling and Optimization of Biomass Pyrolysis

International Journal of Chemical Engineering, Volume 2026, Issue 1, 2026.
Accurate estimation of activation energy (Ea) in biomass pyrolysis is central to process optimization, reactor design, and bioenergy scale‐up. Conventional thermogravimetric analysis (TGA) approaches are resource‐intensive and inadequate for capturing the nonlinear compositional dependencies governing pyrolysis kinetics across diverse feedstocks.

Enhancing In Situ Burning With Ferrocene for Improved Combustion and Reduced Smoke Production

Energy Science &Engineering, Volume 13, Issue 12, Page 5949-5969, December 2025.
ABSTRACT In situ burning (ISB) is an efficient response strategy for oil spills; however, incomplete combustion and excessive smoke production hinder its wider application. In this study, the effectiveness of using ferrocene as additives to improve the thermal behaviors and kinetics of combustion of different crude oils (Hibernia, Hebron, Dilbit and ...
