Abstract—Processing of heavy pyrolysis tar from an EP-300 installation on the KTK-1 catalytic system was
It is known that heavy pyrolysis tar (HPT) contains
condensed hydrocarbon systems with two or more rings.
The topical issues that become increasingly important
in this context are the effective processing of HPT and
its use for synthesis of aromatic oils, luminophors,
technical-grade carbon, coke, and components for
fuels, coatings, and bitumens, as well as the possible
application of HPT in electronics, due to its capacity to
accumulate and transfer electric charge [1–6].
The available published evidence about the
composition, structure, and behavior of HPTs in various
media, furnished by X-ray, optical, radio spectroscopic,
and other methods, is contradictory. Therefore, it is
advisable to primarily perform studies in this area by
using techniques that can identify the composition and
structure of HPTs subjected to chemical and physical
treatments and also to analyze their properties in relation
to methods employed for modiﬁ cation and treatment.
This communication considers with speciﬁ c features
of processing of HPT fractions in the presence of a KTK-
1 catalytic complex in order to obtain naphthalene,
and fuel components and reports data on the effect of
concentration of an HPT fraction on the process of oil
To be stabilized and puriﬁ ed to remove unsaturated
compounds, HPT was treated in the presence of an
aluminum-and-chlorine-containing KTK-1 catalytic
complex by a novel scheme developed at the Institute
of Petrochemical Processes, National Academy of
Sciences of Azerbaijan . The conditions of the
chemical processing of HPT were the following:
temperature 60–80°C; catalyst expenditure per starting
raw material, 0.3–0.5 wt %; and reaction duration 2 h.
The distillation stage was preceded by neutralization of
the polymerizate and its washing to remove the catalytic
complex and neutralizing agent.
After the catalytic treatment, the unsaturated
hydrocarbons of HPT interact with one another and
are converted to macromolecular compounds, thereby
promoting an increase in the naphthalene content
of the 200–250°C fraction from 20.0 to 27.0 wt %.
Thus, unsaturated compounds are removed from the
naphthalene concentrate by the catalytic treatment
and then naphthalene is isolated by rectiﬁ cation and
puriﬁ cation (98–99% purity). It should be noted,
in addition, that the yield of naphthalene from the
235–250°C fraction can be raised by dealkylation of
In catalytic treatment of an HPT fraction (235–
270°C) preliminarily freed of naphthalene and known
as green oil, it becomes unnecessary to perform deep
hydrogenation processing, because use of KTK-1 even
