“…The transesterification reaction can occur using an acid/base catalyst in the presence of methanol/ethanol if the triglyceride feedstock contains less than 2% of free fatty acid (FFA). 4 , 5 Due to food scarcity, the use of edible oils as feedstocks for biodiesel production can be a concerning matter. As a consequence, researchers are looking forward to non-edible oils like rubber seed, Jatropha seed, and Karanja seed oil for their use as potential feedstocks for biodiesel production.…”

“…Single-step transesterification and two-step esterification and transesterification are the popular traditional chemical reaction processes for biodiesel production.

In this study, biodiesel, also known as fatty acid methyl ester (FAME), was synthesized from multi-stage frying waste soybean oil using chicken eggshell-derived CaO and potassium-impregnated K + -CaO heterogeneous catalysts. Potassium-impregnated catalysts (1.25% K + -CaO, 2.5% K + -CaO, and 5% K + -CaO) were developed by treating the calcined waste eggshell powder with KOH in different wt % ratios. The catalysts were characterized using FTIR, XRD, FESEM, EDS, BET, and particle size analysis techniques. Box–Behnken design-based optimization was exploited to optimize the reaction parameters. A maximum yield of 98.46%, calculated via 1 H NMR, was achieved following a 5% K + doping, 12:1 methanol to oil molar ratio, 3% catalyst amount, 180 min reaction time, and 65 °C reaction temperature. The catalyst (5% K + -CaO) responsible for maximum biodiesel production was found to be highly reusable, with a 30.42% conversion decrease in activity after eight cycles of reuse. Gas chromatography was used to determine the composition of FAME produced from different cycles of waste soybean oil. Physicochemical parameters of the synthesized biodiesel were found to be compatible with EN and ASTM standards. This study has shown that the waste eggshell-derived heterogeneous catalysts have significant catalytic activity at relatively low K + doping and catalyst loading leading to high biodiesel conversion.

“…"During the 20th century, the use of non-edible oil seeds products declined substantially due to availability of relatively and cheap oil derived from fossil reserves. Hence, looking into alternative oil source from various seeds remains a subject of active investigation" [6]. "Mahogany (Khaya senegalensis) seed is valued among the best in production of non-fossil oil used for various applications.…”

African Mahogany (Khaya senegalensis) is an important tree in Africa. A deciduous tree, reaching up to 35m in height on fertile soils. It has a diameter of up to 1.5 m with 8-16 m bole. The bark is dark grey or pink with red latex. The plant is commonly found in all the Northern States and around South Western States of Nigeria in the rain forest zone. The plant begins to produce fruit after 15 – 25 years throughout the dry season. The fruit is woody capsule, 4-10 cm long and dehisces at maturity. The seeds have a very low moisture content which is good for oil extraction hence its selection. For the purpose of this study, Mahogany seed, distillation apparatus, jaw crusher, water distiller, chiller, soxhlet extractor, oven, digital weighing balance, n-hexane, are the materials used for the extraction. According to Soxhlet procedure, oil and fat from solid material are extracted by repeated washing (percolation) with an organic solvent, usually hexane or petroleum ether. 325 g of mahogany seed was used in 25-x 80-mm thimble. The Sample has an oil yield of 63.58%, with a cake of 206.62g after extraction and a moisture content of 9% as a result of volatile substance due to high vapor pressures. Further studies on the extraction of oil from mahogany seed is recommended with method other than soxhlet extraction method using n-hexane as extracting solvent as the best method of extraction for end users.

“…The power generation efficiency from the biomass fuel is the most important factor for achieving the potential utilization of biomass (Imran et al, 2012;Rana et al, 2015). Advanced conversion technologies such as pyrolysis (Ganesh and Banerjee, 2001) and gasification (Asadullah, 2014) can offer methods of power generation with higher efficiencies than combustion based steam cycles.…”

Objective of this work was to pyrolysis woody biomass. Experiments were carried out at 300 to 500 o C. Relatively bigger particles were used. Special emphasis was given to investigate the effects of heating rate and heating up time of the central mass of the particles on the product distribution. Surface temperature reached to the reactor set temperature immediately while the temperature at the central part was as low as 50 o C. The center temperature gradually increased to the final temperature within 3 to 8 minutes, depending on the wood types and the reactor set temperature. For ipil-ipil wood the heating rate of the central mass was much faster than krishnachura and koroi woods, and thus the heating up time was lower. Ipil-ipil wood was experienced higher yield (65%) even at lower reactor temperature 300 o C with particle temperature 450 o C. In the case of krishnachura and koroi woods, the bio-oil yields were lower under the same condition due to the heating rates of the central parts were much slower. Further researchon different biomasses may be necessary to demonstrate overall process.
