A comparative evaluation of usage of methyl esters of jatropha and fish oil for environmental protection

Abstract

Economic and societal development of any nation depends very much on the availability of energy sources. Energy sources as an essential input in the areas of any production, but unfortunately the energy sources available are not only limited in volume and quality but also whatever is available are fast getting depleted, storing is necessary for mankind to develop non-conventional sources of energy that not only fulfils the demand but also at the same time keeps the environmental clean or green. Biodiesel takes its place as the most promising alternate fuel because of its renewability and sustainability. Biodiesel is made from rechargeable natural resources that does not produce harmful by-products. Biodiesel can be obtained from various sources like vegetable oils, recycled cooking oil, animal fats and algae, which are cost efficient is easy to make and use. In this work, biodiesel obtained from Jatropha seeds and Fish wastes are used as alternative fuel to diesel in stationary diesel engines. An attempt has also been made to assess the current energy scenario, potential of non-edible oil over edible oils, selected non-edible oil seeds as biodiesel feed-stocks, impact of bio-fuel on environment and future direction. Experimental analysis by different researchers on these non-edible oils has showed their great potential as feed-stocks for biodiesel production. Carbon monoxide (CO), UBHC and smoke emissions are observed to be less at all loads for both the blends compared to diesel fuel while NOx emissions are slightly higher. This paper also reviews the possibility, availability,economic and cost analysis in dept.
