MOSCOW, December 14. Tomsk Polytechnic scientists have developed a technology for producing motor gasoline from gas condensates. According to them, the resulting gasoline meets all the requirements of modern standards and is not inferior in quality to those sold at gas stations. The research results were published in the journal ChemEngineering.
Researchers from Tomsk Polytechnic University (TPU) explained that natural gas, before being used in everyday life, goes through a preparation stage, which results in the production of commercial gas itself and various by-products. For example, stable gas condensates are light and, under certain conditions, liquid hydrocarbons.

"Our country–leader in reserves and production of natural gas, which provides a large volume of by-products. At the same time, there is currently no rational use of stable gas condensates. At best, they are added to oil; at worst, they are burned. Our development will allow us to obtain a product with high added value from a large-tonnage by-product,” said Maria Kirgina, associate professor of the TPU Department of Chemical Engineering.
She added that the developed technology is universal for stable gas condensates of various compositions, therefore it is relevant for all natural gas producing countries.
TPU scientists managed to obtain motor gasoline components from gas condensates by processing gas condensate liquids on a zeolite catalyst, taking into account the influence of catalyst particle size, technological process parameters and raw material composition. Ready-made gasoline blending recipes have also been developed.
“As a possible analogue for the rational use of stable gas condensates, one can probably consider their use as raw materials for petrochemicals. However, in the case of the Russian Federation, this is unlikely; the fields, as a rule, are located in remote areas and there is no possibility of transporting such raw materials to a petrochemical plant.” “, said Ilya Bogdanov, co-author of the development, assistant at the TPU Department of Chemical Engineering.

The technology was immediately developed as a low-tonnage one, making it possible to produce gasoline directly at the field and cover its own needs, as well as sell it in nearby settlements, said another research participant, an engineer from the Research School chemical and biomedical technologies at TPU Andrey Altynov.
He added that an important feature of the technology is the use of domestic catalysts, which makes the development import-independent.
As noted at Tomsk Polytechnic University, Now the project has been fully implemented in laboratory conditions, and the further task of the research team is to move to a pilot installation and create a full-scale technology.
The research was supported by a grant from the Russian Science Foundation.
