Laboratory investigation and many comparisons between laboratory and commercial samples of
Yemeni kerosene distillates were carried out .The physico-chemical properties of the kerosene
distillates were determined . The possibility of their utilization as an aviation turbine fuel with high
quality specification " assisting the increase of flight height and velocity " was confirmed . At the
first look to obtained results , it is shown that the physicochemical properties for all samples are in
the international permissible limits. The carbon content is distributed as the following: 15% normal
paraffin ; 50% branched paraffin ; 2% mono-cycloalkanes ; 16% bicycloalkanes ; 16% branched
mono-cycloaromat with branches prevailing ; 1% bicycloaromat . The samples are not hygroscopic
for long period of time . The smoke point is in higher limits standard . Where the freezing point is
in lower limits standard .These points prove that the Yemeni kerosene might be prepared for a
spectra of jet aircrafts. This Kerosen permit high flying height because it has lower density and
freezing point and it permit high velocity of aviation because it has high percentage of branshed and
cyclparaffins with high specific energy without needed for addition of chemical additives, but
may be need for portion of isomers of paraffin.
