Предложены новые нанесенные катализаторы на основе платиновых металлов для реакции дегидрирования смеси легких алканов в соответствующие олефины, приготовленные методом пропитки по влагоёмкости. Структура свежеприготовленных и отработанных катализаторов 3 % Pt, Pd, Ru на y-Al2O3 были исследованы физико-химическими методами ПЭМ, РЭМ, БЭТ. Для определения распределения частиц на поверхности катализаторов были построены кривые распределения частиц по размерам. Превращение смеси легких алканов в восстановительной среде проводили на лабораторной установке проточного типа на стационарном слое катализатора при атмосферном давлении. Представлены сравнительные таблицы конверсии смеси легких алканов на платиновых металлах, нанесенных на y-Al2O3 в четырех режимах, в интервале температур 350-500  °C. Наибольший выход наблюдался на 3 % Ru/y-AlO при совместной подачи смеси легких алканов с водой при 500 °C. Вода, не участвуя в составе конечных продуктов реакции, смещает равновесия в системе, образуя на поверхности катализатора диссипативные структуры.</p></abstract><trans-abstract xml:lang="en"><p>Mixtures of light alkanes simulate associated gas of oil production, the problem of processing of which remains relevant both in the world and in Kazakhstan. New supported catalysts based on platinum metals have been proposed for the dehydrogenation reaction of a mixture of light alkanes to the corresponding olefins prepared by the impregnation method according to moisture capacity. The structure of freshly prepared and spent catalysts 3 % Pt, Pd, Ru on у - Al2O3 were prepared by physicochemical methods TEM, SEM, BET. The particle size distribution curves were made up to determine the distribution of particles on the surface of the catalysts. The conversion of a mixture of light alkanes in a reducing environment was carried out in a laboratory flow-type installation on a stationary catalyst bed at atmospheric pressure. The conversion of a mixture of light alkanes on platinum metals supported on у - Al2O3 in four modes is presented on comparative tables in the temperature range of 350-600 °C. The highest yield was observed at 3 % Ru / у - Al2O3 with the joint feeding of a light alkanes mixture with water at 500 °C. Water does not participate in the composition of the final reaction products but shifts the equilibrium in the system, forming dissipative structures on the catalyst surface.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>дегидрирование</kwd><kwd>катализатор</kwd><kwd>низшие алканы</kwd><kwd>водород</kwd><kwd>этилен</kwd><kwd>пропилен</kwd><kwd>олефины</kwd></kwd-group><kwd-group xml:lang="en"><kwd>dehydrogenation</kwd><kwd>catalyst</kwd><kwd>lower alkanes</kwd><kwd>hydrogen</kwd><kwd>ethylene</kwd><kwd>propylene</kwd><kwd>olefins</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Sokolsky D.
