Recent Development in 2nd Generation Biodiesels as Alternative Fuels for Transport Sector

Abstract: Increase in global energy demand due to increase in population and industrial growth has lead the researchers to look for alternative fuel for transport sector. Among the options, biodiesel has potential to give a solution to the energy concern due to being renewable, biodegradable and environmental friendly nature and have similar properties of fossil diesel. There are three types of biodiesels available, namely 1st generation biodiesel which produces from edible oils; 2nd generation biodiesel which produces from non-edible oils and animal fats, and 3rd generation biodiesel which mainly produces from microalgae. Among the different types of biodiesels, 2nd generation has the better potential as an alternative to petroleum diesel because it does not compete with food vs fuel crisis and it’s feedstocks are available sufficiently and can be grown throughout the year in marginal lands as opposed to fertile land required for growing 1st generation biodiesel feedstocks. On the other hand microalgae biodiesel has limited availability and still in the early stages of development. This presentation will summarize the challenges of producing biodiesel from 2nd generation biodiesels feedstocks and will identify the operating conditions for obtaining optimised and highest oil yield and efficient conversion of bio-oil into biodiesel. An example will be provided on biodiesel production from Australian beauty leaf tree (BLT) (Calophyllum inophyllum). Then, engine performance, combustion and emission characteristics using petroleum diesel and biodiesel-diesel blends of B5, B10 and B20 for different 2nd generation biodiesels, for example BLT biodiesel, poppy and waste cooking mixture biodiesel, jojoba biodiesel, etc, will be presented and evaluated. The test results from 4-cylinder diesel engine dynamometer test-bed running at engine speed from 1200 rpm to 2400 rpm with 200 rpm increment and engine load of 25%, 50%, 75% and 100% will be presented and discussed. The presentation will provide researchers, policy makers and biodiesel manufacturers an understanding of using 2nd generation biodiesel as an alternative source of fuel for diesel engine. Keywords: The 2nd generation biodiesel, Australian beauty leaf tree (BLT) biodiesel, bio-oil extraction, biodiesel production, diesel engine performance, emissions and combustion characteristics.
