TOMSK,
Mar 2 – RIA Tomsk. Scientists of the Laboratory of catalytic research of Tomsk State University (LCR TSU) work on creation of the selective vanadium catalyst which
will allow to make technology of industrial production of propylene more
eco-friendly and energy-efficient, the press service of the university reports
on Thursday.
"Today
the consumption of unsaturated hydrocarbons, in particular, propylene, steadily
grows, at the same changes time the logistics in the field of their receiving
and using. Therefore search of new approaches to creation of catalysts of this
process becomes one of urgent problems of a modern catalysis", – the
research supervisor of the project, LCR TSU senior research associate Tamara
Kharlamova is quoted in the message.
It is noted
that the main method of propylene receiving is – oil processing, however here
it is only a by-product and not always has sufficient purity. At other way –
catalytic dehydrogenation of propane – on the catalyst coke is laid, and it
needs continuous regeneration that is too energy-intensive.

It is
explained that these shortcoming are lack by oxidative dehydrogenation. Less of
this – is a small share of the propylene received as a result of reaction. The
TSU catalyst will allow to increase selectivity of reaction, and, perhaps, in
the future in the Russian Federation the first-ever improved technology of
propylene production will be realized.
"Due
to use of the modified vanadium catalysts we already managed to increase
selectivity of process for 10% in comparison with the put vanadium catalyst.
For the competitive catalyst it is necessary to achieve selectivity not lower
than 90% at 10% of conversion", – the press service quotes undergraduate
of chemical faculty and the employee of LCR TSU Ekaterina Sushchenko.
It is
reported that the project is carried out with assistance of the
"UMNIK" program. In the next two years scientists plan to raise an
yield of propylene and then to submit the patent application.
Propylene –
is one of the major monomers which is used for production of polypropylene,
rubbers and plastic. It is raw material for production of acetone, isopropyl
alcohol, acrylonitrile, is a part of motor fuel and solvents.
