Due to the synergistic effect that occurs between CNTs and alumina, CNT/alumina hybrid-filled epoxy nanocomposites show significant enhancements in tensile properties, flexural thermal conductivity. This study is an extension of previously reported investigations into nanocomposites. A series composites with different loadings were investigated regard their thermal-degradation kinetics lifetime...

In this study, the combustion of olive byproducts was investigated using TG-FTIR technique. Different types biomass were considered: twigs, leaves, olive-mill waste from two-phase decanting method, and wastewater three-phase system. The reaction regions, ignition, burnout temperatures at different heating rates determined TG/DTG analysis thermogravimetry results. Comprehensive combustion, burno...

The pyrolysis performances and reaction kinetics of pine needles (PN) were investigated by integrating thermogravimetric analysis, Fourier transform infrared spectroscopy, pyrolysis-gas chromatography/mass spectrometry. average activation energy PN was estimated to be 183.2 kJ/mol Kissinger Akahira Sunose (KAS) 183.8 Flynn Wall Ozawa (FWO), respectively at heating rates 10, 20, 40 °C/min. found...

In order to prevent the spread of Covid 19, most countries have made face masks compulsory. Millions are disposed daily in community. Therefore, aim present research work is carry out pyrolysis and combustion process mask a thermogravimetric machine. The kinetic parameter activation energy was calculated using model-free methods (Flynn-Wall-Ozawa, Kissinger-Akihara-Sunose, Starink) at four diff...

A thermal behavior study of lipid-extracted Nannochloropsis gaditana (LEA) was performed in a thermogravimetric analyzer. The by heating the sample under different rates (5, 10, and 15 °C/min) from room temperature to 1000 °C using N2 gas as medium. This is crucial for stability studies kinetic control regime. following three stages chemical decompositions were found: (1) moisture removal (2) d...

The surge of face mask waste in response to the global pandemic has proven be a liability environment. Microfibers from plastic constituents would cause microplastic pollution water bodies. Fortunately, these could converted into renewable source energy via thermochemical method, i.e. pyrolysis. However, studies on thermal decomposition masks and their kinetic mechanisms are not well-establishe...

The aim of this study is to examine the behaviour melon seed pyrolysis and calculate its kinetic parameters along with thermodynamic properties. thermogravimetric analysis experiments were conducted from ambient temperature 800°C under nitrogen atmosphere at heating rates 5, 10, 20 40°C/min. It was determined that process underwent through four stages where second third active stages. Kinetic c...

Abstract As an alternative energy source for fossil energy, use of biomass pyrolysis to reduce pyrolusite is great significance conservation, emission reduction and environmental protection. Kinetics thermodynamics reducing using was studied thermogravimetric analysis analysis. Five non-isothermal methods, Flynn-Wall-Ozawa, Kissinger-Akahira-Sunose, Distributed Activation Energy Model, Starink ...
