The chloroform bitumen "A" family consists of 5.60-50.58% saturated hydrocarbons
, 21.10-34.10% aromatic hydrocarbons, 20.17-60.64% nonhydrocarbons and 2.69-33.77% asphaltenes.
The data of group component shows that, for crude oil samples, the content of saturated hydrocarbons
is 43.75-76.95%, with an average of 63.37%; the content of aromatic hydrocarbon is 4.21-11.99%, with an average of 8.37%; the content of asphaltene + nonhydrocarbon is 15.40-44.26%, with an average of 28.26%; the value of saturated hydrocarbon/aromatic hydrocarbon is 3.65-17.27%, with an average of 8.47%.
The paraffin crystals in the saturated hydrocarbons
of the heavy oil before and after aquathermolysis were examined under a BX41-P OLYMPUS polarizing microscope at temperature of 5 AdegC.
Gas chromatograms of the saturated hydrocarbons
isolated from the oil shale samples under study are shown in Figure 7, their parameters are given in Table 3.
It was found that all the fractions were mainly composed of saturated hydrocarbons
with good percentages of unsaturated hydrocarbons.
Isoprenoid alkane in saturated hydrocarbon
fractions is primarily composed of phytane series.
These are alkanes (saturated hydrocarbons
having a linear or a branched structure), alkenes (hydrocarbons with double bonds), cycloalkanes (saturated hydrocarbons
containing a ring), and aromatic hydrocarbons (molecules containing benzene rings) [1, 2].
The majority of the hydrocarbons on the filter represented long chain hydrocarbons with a dominance of [C.sub.21]-[C.sub.30] saturated hydrocarbons
(normal and branched), [C.sub.21]-[C.sub.30] cyclic, PAH, multi-oxygenated compounds, and low boiling point iso-aromatics.
Nullity of a chemical graph is related to the stability of saturated hydrocarbons
The data from air monitoring for the period 2005-2009 were used in the settlements of the study area according to the following values: hydrogen sulfide, saturated hydrocarbons
C1-C10, benzene, sulfur dioxide, carbon monoxide, nitrogen oxide and dioxide, methane, suspended solids.
These mineral oils contain aromatic and saturated hydrocarbons
that can be easily absorbed and over time, accumulate in the body.
Cyclic saturated hydrocarbons
such as decalin, bicyclohexane, methylcyclohexane, and are proposed as new mobile hydrogen storage media for proton exchang membrane fuel cells.
