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-
