Effect Of Fatty Acid Methyl Esters (Fame) On Physical And Chemical Properties Of Aviation Turbine Fuels

Karp G.

Journal of Polish CIMAC

2009

Vol. 4, no 2

91-101

In recent years there is tendency to adjust domestic petroleum products to meet world and European standards that establish high requirements regarding environment protection. At the same time, it is tendency to introducing wider spectrum of biocomponents that in turn enables to reduce harmful influence on environment. The work described in this paper, among others, consists in evaluation of effect of various concentration of FAME in aviation turbine fuel on its physical and chemical properties. The research work includes effect of FAME on fuel properties regarding the refinery process (density, distillation, flash point, composition, and the like) but also on properties important in regard to engine operation (kinematic viscosity, acid number, oxidation stability, gum content, freezing point, and the like). The work covers also the effect of selected antioxidants and depressants on FAME containing fuels on turbine engines operation. Considering the environment protection, the work includes evaluation of FAME presence on sulphur content, carbon and ash content. In order to establish stability - resistance to different ambient conditions - such blends undergo cyclic temperature changes. Results will be used to evaluate the possible use of biofuels in turbine engines.
