Investigation of the Combustion, Emissions, and Engine Performance Characteristics of Cottonseed Biodiesel for use in Power Generation
… generators. Fuel properties including viscosity, oxidation stability, lower heating value, thermo-gravimetric and differential thermal analysis, and spray characteristics were analyzed. Fuel property measurements were comparable to ULSD#2 in every aspect except oxidation stability which showed the …

Tribological performance of jatropha oil-based nanofluids for orthogonal cutting process
… limitation of using CJO is low thermal and oxidation stability that leads to poor lubrication behaviour. Hence, the aim of this study was to develop and evaluate the nanofluid formulations from modified jatropha oil (MJO) as the MWF. The MJOs were formulated from jatropha methyl ester with …

Heterogenkatalysierte elektrophile Addition am Beispiel der Hydratisierung von Ethylen und Alkoxylierung, Acyloxylierung von Oleochemikalien
… These should be chemically modified, so that the oxidation stability, the lubricating and tribological properties improve and the biodegradability of the new lubricant is maintained. Five new lubricants could be produced by the addition of three different carboxylic acids (formic acid, acetic acid …
