Biodiesel from non-edible Karanja seed oil

Abstract

The fossil fuel resources are dwindling day by day. Fuel has been a challenge for today’s scientific works for increasing demand. The methyl esters of vegetable oils, known as biodiesel are becoming increasingly well known because of their low environmental impact. Methyl esters of Pongamiapinnata are derived through esterification and transesterification. Several processes of biodiesel fuel production has been developed, among which transesterification using alkali as a catalyst gives high level of conversion of triglycerides to their corresponding methyl ester in a short duration. Amount of solvent, catalyst, temperature and reaction time were optimizedfor estimates the conversion efficiency. The physical properties of Karanja seed oil (KSO) and biodiesel were studied and compared with standard. FTIR and TGA spectrums of KSO and KSO Biodiesel were studied for the confirmation of conversion.Bangladesh J. Sci. Ind. Res. 52(1), 15-20, 2017

Triglyceride Conversion of Waste Frying Oil up to 98.46% Using Low Concentration K+/CaO Catalysts Derived from Eggshells

“…As economically viable and ecologically sustainable alternative energy sources to conventional petrodiesel, liquid biofuels have caught the attention of researchers. 2 Fatty acid alkyl esters, generally known as biodiesel, derived from organic sources, such as vegetable oils, animal fat, or waste cooking oil, are a proven alternative to conventional diesel owing to its significant and non-toxic fuel properties. 3 Single-step transesterification and two-step esterification and transesterification are the popular traditional chemical reaction processes for biodiesel production.…”

“…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. 2 , 6 − 8 However, owing to the scarcity of non-edible oils and the consequential high cost of biodiesel produced from them, waste cooking oil (WCO) has become a reliable source for biodiesel production. 9 Choice of feedstock mainly contributes to the final product’s price, and, as WCO is widely available across the globe, producing biodiesel from it is an economically very viable option.…”

Abiding effects of phenolic antioxidants on oxidative behaviour of fatty acid methyl esters derived from waste cooking oil

“…In the esterification process, H2SO4 was dissolved in alcohol using a standard agitator and adding WCO in the mixture. The reaction mixture was transferred into a 1 L bioreactor and maintained reaction condition for 400 rpm stirring speed at 60 °C for 1 h. The mixture was settled for 1.5 h, and the methanol-water-catalyst fraction from the top layer of the separating funnel was removed (Alam et al 2017). The lower part of the mix was then collected, and the free fatty acid (FFA) percentage was measured.…”

“…Fossil fuel reduction, environmental concern, and unbalanced crude oil prices have increased the need for alternatives to fossil fuels. Additionally, climate change and other ecological risks have prompted all nations to diminish their reliance on fossil fuel (Ramaraju and Kumar 2011;Alam et al 2017). Biodiesel is a sustainable, biodegradable, and eco-friendly elective fuel that is used as a substitute for petroleum-based diesel (Hossain et al 2014;Saluja et al 2016).…”

“…Raw materials are a vital issue for biodiesel use in the commercial sector. Due to food security, researchers have preferred the use of non-edible oils such as jatropha seed, rubber seed, and Karanja seed oil together with waste cooking oil as a potential feedstock for biodiesel production (Ramaraju and Kumar 2011;Hossain et al 2014;Khalid et al 2014;Alam et al 2017). In this study, waste cooking oil from different restaurants in Dhaka, Bangladesh, was collected for biodiesel production.…”
