1 IMPROVING ETHANOL-DIESEL BLEND THROUGH THE USE OF HYDROXYLATED BIODIESEL Ekarong Sukjit Suranaree University of Technology José Martín Herreros, Karl Dearn, and Athanasios Tsolakis The University of Birmingham

2 Content Introduction Aim Experimental apparatus and materials Results and discussion Lubricity Combustion characteristics Emissions Conclusions Paper #

3 Introduction Environment concerns about emissions More stringent emission standards (THC, CO, NOx, PM) Use of energy from renewable sources 10% for bio-fuel consumption in the transport section before 2020 (2009/28/CE) Environmentally friendly and renewable fuel needed. Paper #

4 Introduction Alcohols as an alternative fuel for ICE Benefit of oxygen in fuel molecules (reduce soot formation) Contribution of biofuels (produce from crop, waste biomass, crude glycerol, algae etc.) Reduction in life-cycle green house emissions (lower C/H ratio, CO 2 required by production) Reduction in the dependence upon foreign oil in non-producing countries Used as fuel for vehicles (SI & CI engines) Paper #

5 Introduction Not Feedstock for vegetable oil Biodiesel Diesel +Alcohol Additive? Diesel +Alcohol +COME Castor Oil Methyl Ester Low cetane number Bad lubricity Low heating value Low miscibility Higher cetane number Better lubricity Higher heating value Better miscibility Paper #
