1. Research Updates Kapila Wadumesthrige 03/04/08

2. Engine testing (Kapila, Sidong, Mark and Nick) –Total run time = 292 hrs –Total testing time ( 30 kW (60% of Full Load, ULSD) = 205 hrs –35 hrs of testing remaining ( 4 days) –500 gallon tank empty –Need about 50 gallons of ULSD –Clean fuel tank for S8 –Continuous Lube oil analysis –Metal analysis –Fuel Injector system durability testing

3. Antioxidants and cetane improvers act against each other Cetane improvers in B20 (ULSD) may help oxidize biodiesel and degradation of antioxidants Received two cetane improvers – 2-ethyl-hexyl nitrate (EHN) – di-tert-butyl peroxide (DTBP)) Stability of antioxidants in the presence of cetane improvers Effect of Cetane improvers on oxidation stability of Biodiesel

4. ICP testing –All metal standards and solvents received –Compressed air line installed (Mark & Danton) –Methods for Biodiesel and Lube oil analysis

5. AOCS Abstract 1 Properties of Modified Fatty Acid Methyl Esters Kapila Wadumesthrige, Mark Winston-Galant, Sidong Zeng, Steven O. Salley, K. Y. Simon Ng 1. Modification of double bonds Hydrogenation (higher Ox stability, Low flow properties) -HC=CH- -CH 2 -CH 2 - 0.4 wt% Ni, 5.0 wt% H2 400 kPa pressure, 160 C temperature

6. Hydroxylation -HC=CH- -CH(OH)-CH(OH)- Alkaline KMnO 4,, 70-90 C Epoxidation -HC=CH- -CH-(O) -CH-
