This study investigates the thermodynamic and advanced nonlinear kinetic modeling of neem oil extraction using hexane as a solvent, aimed at advancing second-generation feedstock for environmental sustainability. Key process parameters—extraction temperature (32 °C to 74 °C), particle size (0.1 mm 0.5 mm), time (0 180 minutes)—were systematically investigated assess their effects on yield diffusion coefficients. Six models, including power law, parabolic diffusion, hyperbolic, Elovich,...
The aim of this work is to investigate the corrosion inhibition B. eurycoma leaves extract as a natural inhibitor for mild steel in 3 M H2SO4 solution. inhibitory activity was analyzed by electrochemical impedance spectroscopy (EIS) and potentiodynamic polarization. surface roughness its properties through scanning electron microscopy (SEM). obtained result from EIS divulges that gradual increase concentration time immersion leads progressive efficiency. At end 8 hours 1000 mg/l highest...
The aim of this study is to convert mixed plastic waste into usable liquid fuel via pyrolysis technique using Ukpor clay as a low-cost catalyst and commercial grade kaolin. Waste was catalytically degraded in laboratory scale semi-batch reactor at temperature 400 °C, residence time 45 min, heating rate 16 ˚C/min. catalysts were characterized by XRF analysis while proximate the feed carried out gave volatile materials content 95.17 wt%, fixed carbon 1.51 wt% ash 2.6 wt%. kaolin employed...
