Abstract—Samples of silicon dioxide-modiﬁ ed nanospherical carbon were synthesized by thermooxidative
pyrolysis of highly aromatized liquid hydrocarbons with a varied content of organosilicon polymer
(polyorganosiloxane). The physicochemical properties of the product synthesized were studied.
Owing to unique physicochemical and physicom-
echanical properties, nanosize carbon materials of various
forms and structures and especially composites on their
basis arouses sustained interest [1–3]. In addition, range
of application of these materials is steadily expanding
Nanosize carbon spheres including those modiﬁ ed
with various elements or with their compounds are of
most practical importance, because they enable properties
of the compositions to be varied within wide range [6,
7]. Only scanty data of qualitative character are available
from the literature on the synthesis, design, and properties
of the above nanoparticles. This is because their synthesis
proceeds at high rate, needs complex engineering equip-
ment, and therefore is poorly understood.
The synthesis of carbon-silicon nanocomposites,
which may be used as ﬁ llers to reinforce elastomer
properties, is the promising direction in development
of modiﬁ ed nanosize carbon materials. These materials
may be promising for the manufacture of low rolling
resistance tires with good grip to the road [8–12]. Along
with this, highly dispersed silicon dioxide incorporated
into nanoporous carbon materials under conditions of
its strong binding to a carbon phase can markedly affect
stabilization of the catalyst precursor on a pore surface
of carbon support [13, 14].
In this study, silicon-containing nanodispersed carbon
(NDC) was obtained by high-temperature synthesis based
on simultaneous decomposition of highly aromatized
liquid hydrocarbons and polyorganosiloxane.
Silicon-containing nanodispersed carbon was syn-
thesized by thermoxidative pyrolysis at temperature
1450 ± 10°С and under the pressure 0.12 MPa on a pilot
plant reactor (Fig. 1). Consumption of hydrocarbons was
500 kg h
As liquid hydrocarbons were used a highly aroma-
tized mixture of anthracene fractions of coal tar pitch
and heavy pyrolysis resin (ratio 0.75 : 0.25). The ratio of
the hydrogen to carbon atoms (H/C) in a medium mol-
ecule of raw material was 0.9. As organosilicon additive
served poly(dimethylsiloxane) liquid of the composi-
50), which was introduced into the raw material prior
The synthesis was performed by the following manner.
Natural gas was burnt in the initial zone of the reactor
equipped with a ring gas burner of complete mixing,
ensuring radial streams. Annular expanding ﬂ ow of the
complete burning products containing excess oxygen
entered the reaction zone at 1400°С in the same direction.
