Comparative study of gasification and pyrolysis derived from coconut shell on the performance and emission of CI engine

Abstract The depletion of fossil fuel and environmental impacts due to emissions of IC engines forces the researchers to discover various alternate fuels. The project aims to develop the bio-fuel by various methods from a feedstock and analyzes the properties of the fuel. The locally accessible wastages were used to substitute fuel for diesel in the appropriate manner. Waste management is an important factor that has an impact on the development and the welfare of the population. In this project, an attempt has been made to evaluate the pyrolysis and gasification process. Pyrolysis oil has carboxylic acids, alkenes, aromatics, alkaline and little gaseous amount yield from the pyrolysis process. In the gasification process the producer gas was obtained. At these optimum process conditions, the obtained pyrolysis oil and producer gas were analyzed for physical and chemical properties to be used in the CI engine as an alternative fuel. The performance parameters like brake thermal efficiency (ƞBTE), brake specific fuel consumption (BSFC) and emission parameter like carbon monoxide (CO), carbon dioxide (CO2), hydrocarbon (HC), oxides of nitrogen (NOX) and smoke emission were examined.
