Abstract
Biodiesel production from non-edible vegetable oils is an effective way to conquer the linked problems with edible oils such as food versus fuel and other environmental impacts. Cerbera odollam oil is one of these possible non-edible feed stocks for future biodiesel production. This study evaluated the potential biodiesel production from cerbera odollam. The seed was collected and extracted from Aceh, Indonesia. Moreover, biodiesel has been produced using degummed (H3PO4) and two step acid catalyst (HCl) and alkaline catalyst (KOH). The results of properties of the cerbera odollam methyl esters show that such as viscosity was about 847.9 mm2/s, density was 3.1578 kg/m3, flash point was 214.0°C, acid value was 0.4 mg KOH/g, oxidation stability was 6.35 h, FAME content was 97.77 % w/w and heating value was 40.49 MJ/kg. After analysing these properties, it has been found that there is a huge chance to produce biodiesel from this seed which complies with the limits of ASTM 6751 and EN 14214 specifications and therefore it can boost the future production of biodiesel from non-edible sources.
Highlights
The diminishing supply of fossil fuels reserves and the growing environmental concerns have made renewable energy an exceptionally attractive alternative energy source for the future [1,2]
The acid value of COME was observed to be 0.47 %. These results are in agreement with the value specified in ASTM D664.The heating value of cerbera odollam methyl ester was found 39.46 MJ/kg respectively
The evaluation of biodiesel production using two step acid esterification and alkaline transesterification was performed in order to obtain high methyl ester yield
Summary
The diminishing supply of fossil fuels reserves and the growing environmental concerns have made renewable energy an exceptionally attractive alternative energy source for the future [1,2]. Biodiesel is a promising alternative fuel for diesel fuel. It is defined as the mono-alkyl esters of long chain fatty acids derived from vegetable oils or animal fats and alcohol with or without a catalyst. It is renewable, biodegradable non-toxic, portable, readily available and eco-friendly fuel [3]. The Indonesian government has developed alternative fuel to tackle the energy crisis to solve the economic revival of society. To the best of the author’s knowledge, limited study on the possibility of cerbera odollam oil as a potential non-edible oil feed stock for biodiesel production has been reported in the literature
