Abstract Microwave-assisted synthesis is known to accelerate the transesterification process and address issues associated with conventional thermal process, such as processing time energy input requirement. Herein, effect of microwave irradiation on palm oil methyl ester (PME) trimethylolpropane (TMP) was evaluated. The reaction system investigated through five parameters, which were temperature, catalyst, time, molar ratio TMP PME vacuum pressure. yield triester at 66.9 wt.% undesirable...
Enhancement of reaction performance utilizing microwave irradiation has drawn so much interest due to its shorter time and low catalyst loading. These advantages are particularly significant from kinetics thermodynamics perspectives. This study aimed investigate the microwave-assisted transesterification palm oil-based methyl ester into biolubricant. The oil (PME) trimethylolpropane (TMP) was conducted at 110–130 °C for 90 min under vacuum condition. Sodium methoxide employed as 0.6 wt%...
A solar panel, also known as a photovoltaic (PV) converts photons from sunlight into usable energy. However, panel warming during the day limits voltage production and results in energy-electricity waste. The efficiency of this PV panel's cooling system utilizing water aluminum oxide (Al2O3) nanofluid was simulated assessed using Computational Fluid Dynamics (CFD). This research examines thermal performance temperature differences between uncooled, water-cooled, Al2O3 nanofluid-cooled...
Abstract Palm oil mill effluent (POME) and palm empty fruit bunches (EFB) constitute the highest waste generated in mill. This study investigates thermochemical approaches, specifically wet torrefaction gasification, aiming to transform these wastes into higher-value products such as biochar. Wet was initially applied EFB POME at 200 °C, with a heating rate of 5 °C/min for 30-min residence time under nitrogen-inert conditions, resulting solid yield 82%. process led notable increase value raw...
Abstract In Malaysia, the palm oil industry generates vast amounts of solid and liquid waste, including empty fruit bunches (EFB) mill effluent (POME). Finding efficient environmentally friendly ways to manage utilise this waste is crucial for sustainability. The research explores utilisation wet torrefaction in water EFB, examining its impact on anaerobic digestion, specifically dark fermentation (DF) process. product torrefied EFB was further investigated as a substrate biohydrogen...
Abstract The palm oil industry in Malaysia has aided our economy, but with any thriving comes the baggage of industrial waste. This paper focuses on mill effluent (POME), a waste product formed by milling operations. objective this is to evaluate ability POME generate biogas through acid and heat pre-treatment methods. feasibility producing at pH levels lower than 5 was investigated. inoculum effective microbe 1 (EM1), substrate liquid POME. Hydrochloric phosphoric were used study, effect...
