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 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...

Efficient waste management, including proper utilization of municipal solid (MSW), is imperative for a sustainable future. Among several management options, pyrolysis and combustion MSW has regained interest because improved techniques. This work aims to investigate the thermal conversion characteristics refuse derived fuel (RDF) samples its individual compounds collected from Nur-Sultan’s land...

Thermogravimetric analysis (TGA) was utilised to compare the thermal stability of pure phase change material (D-mannitol) that nano-enhanced PCM (NEPCM) (i.e., containing 0.5% and 1% multiwalled carbon nanotubes (MWCNT)). Using model-free kinetics techniques, NEPCM degradation were analysed. Three different kinetic models such as Kissinger-Akahira-Sunose (KAS), Flynn-Wall-Ozawa (FWO), Starink a...

The 3D metal–organic framework (MOF), MIL-88B, built from the trivalent metal ions and ditopic 1,4-Benzene dicarboxylic acid linker (H2BDC), distinguishes itself other MOFs for its flexibility high thermal stability. MIL-88B was synthesized by a rapid microwave-assisted solvothermal method at power (850 W). iron-based [Fe3.O.Cl.(O2C–C6H4–CO2)3] exposed oxygen iron content of 29% 24%, respective...

Exhausted coffee residue (ECR) and husk (CH) are potential feedstock for energy production through thermochemical biochemical conversion processes. Kinetic study of ECR CH is essential the design optimization different In this study, four iso-conversional methods were employed in estimation activation (EA) pre-exponential factor (A). The used includes Flynn-Wall-Ozawa (FWO), Kissinger-Akahira-S...

Polystyrene/polyolefin elastomer (PS/POE) (90/10 and 80/20 wt/wt) blends containing 1, 3, 5 phr halloysite nanotubes (HNTs) in the presence absence of a compatibilizer (polypropylene-graft-maleic anhydride) were prepared using melt-mixing technique. Scanning electron microscopic studies confirmed matrix-droplet morphology. Energy dispersive spectroscopy (EDS) mapping indicated that HNTs possess...

Abstract The effects of particle size on the apparent kinetics carbothermal reduction process phosphate rock were studied by non-isothermal thermogravimetric analyses. Phosphate various was reacted with coke and silica under high purity argon atmosphere. kinetic model parameters reaction different sizes derived combination model-free (Flynn–Wall–Ozawa, Kissinger–Akahira–Sunose, Tang, Starink) m...

The aim of the research presented in this article was to analyse processes source-rock decomposition, including kinetic parameters pyrolysis, relation type organic matter and its maturity. examined source rocks were Menilite shales from several units within Flysch Carpathians (Poland). samples analysed with use thermal methods, Rock-Eval thermogravimetry coupled an FTIR detector. Kinetic determ...

This framework focuses mainly on a detailed study of the pre-crystallization criteria that characterize As40S45Se15 glassy alloy in various heating rates ranging from 5 to 40 (K/min) by Differential Scanning Calorimetry (DSC). These aim clarify relationship tendency glass-forming rate for investigated alloy. The crystallization parameters were calculated using different methods.The activation e...
