Experimental investigations on effect of nanoadditives in the behaviour of diesel engine fueled with diesel pyrolysis oil blends

Abstract

newline The climate change and the striving for security of energy supply are serious issues for the recent days. The modern lifestyle leads to higher consumption of energy and goods. Apart from the scarcity of goods, the global issues such as climatic changes, problem of air, water and soil pollution, incessant mounting of fossil fuel price and stringent emission norms imposed by government laws are the main drive behind expanding the exploration of non-conventional energy sources. The nano-additives facilitate as a catalyst in liquid fuel which changes its chemical composition and helps in boosting the quality of the fuel. It also can improve the performance and combustion attributes substantially when it is used as a fuel additive for IC engines. The nanoadditive has higher surface energy owing to their greater surface area. The nano-scale additives also improve the fuel oxidation characteristics to minimize the deleterious pollutants exhausted from diesel engine. In this work, the focus is given to the production of bio-oil from jatropha oil seeds and waste plastics separately through catalytic pyrolysis process and simultaneously used as a fuel for IC engine. Initially the thermogravimetric and (TGA) and differential thermogravimetric (DTG) techniques were used to observe the thermal behavior of jatropha oil seeds and waste plastics. After extracting pyrolysed biomass oil (PBO) from jatropha seeds, the esterification of PBO has been carried out using a catalyst in the presence of methyl alcohol to improve its physical properties and quality. The transestified biomass oil and raw waste plastic oil (WPO) are tested for its physical and chemical properties.
