Abstract
Abstract:The sustainable production of ethanol from non-edible fruit and their wastes is focused in the current investigation. Bio-ethanol is a fuel ethanol (ethyl alcohol), the same type of alcohol found in alcoholic beverages. It is most often used as a motor fuel, mainly as a bio-fuel additive for gasoline. In the present research study, an attempt has been made to obtain a fuel grade ethanol using fruit samples like, Passion fruit (Passiflora edulisL)and Cashew Apple (Anacardium occidentaleL.) by fermenting them with the help of flocculating yeast (Saccharomyces cerevisiae, L). As we could obtain 48% alcohol after distillation s, we can envisage that, an optimized concentration of ethanol can be obtained after standardization of the protocol. This bio-ethanol can be used as bio-fuel. As this process is cost effective, much cleaner, eco-friendly and do not yield any toxic residues or gases; so a common man can develop this technique which can able to produce ethanol at industrial level. Therefore, in the present attempts, technological attributes of flocculated Yeast (Saccharomyces cereviseae) was employed to enhance its use in alcoholic fermentation, they produce bio-ethanol in the selected fruit cultivars at significant extent in a speed about three to four times greater than the yield reported in the earlier studies. Among the samples evaluated for the yield of ethanol, sample-4 (Passion fruit juice) gave 100% purity of ethanol as compared to standard. The bio-ethanol obtained as a result of fermentation was subjected for the evaluation of Engine performance using single cylinder engine with standard specifications. It revealed a most significant performance with the variable blend of Bio-ethanol and Petroleum diesel (B10-15). Besides, a remarkable reduction in the production of hazardous gases (NOX) with the blends of bio-ethanol (B10-15) was observed. The bio-ethanol produced from non-edible fruit samples was found to be of high quality, which can be utilized as an alternative fuel in the engine system as it meet the ASTM standards with regards to performance and emission parameters especially viscosity and metal content. Hence, a good quality bio-ethanol production form non-edible fruit samples has been justified which can be used further in the industries explicitly by Automobiles and transportation.
