Для интенсификации процесса применены активаторы межфазного переноса О2, позволившие значительно повысить скорость поступления газа в реакционное пространство без дополнительного потребления энергии в отличие от широко применяемых методов перемешивания и барботажа. Исследовано влияние ряда веществ на KLa при варьировании скорости перемешивания от 100 до 1200 об/мин. Впервые сопоставляются по эффективности твердо- и жидкофазные активаторы. Максимальный рост KLa при разных гидродинамических условиях достигнут для активированного угля (в 3,7 раза), аэросила (в 1,5 раза), н-додекана (в 3,1 раза). Результаты объяснены «челночным» механизмом межфазного переноса О2. Показано, что при увеличении KLa с 2,8 до 18,5 ч–1 биокаталитическое окисление фенола ускоряется в 2,4 раза. Использование активированного угля как активатора межфазного переноса О2 позволяет повысить скорость биокаталитического окисления фенола примерно на 20 %.</p></abstract><trans-abstract xml:lang="en"><p>Transport of oxygen from the gas phase to the aqueous determines the rate of biocatalytic oxidation of phenol. In this paper, activators of the interphase transfer of O2 are used to intensify the process, thus significantly increase the rate of gas arrival in the reaction space without additional power consumption in contrast to the widely used methods of mixing and bubbling. The authors presented the results of studies of the effect a number of substances on the value of KLa at varying mixing speeds from 100 to 1200 rpm. We report the first solid-liquid phase and activators are compared for effectiveness. The maximum KLa increase at different hydrodynamic conditions achieved for the activated carbon (3,7 times), aerosil (1,5 times), n-dodecane (3,1 times). The results are explained by «shuttle» mechanism of O2 phase transfer. It is shown that an KLa increasing from 2,8 to 18,5 h–1 the biocatalytic oxidation of phenol is accelerated in 2,4 times. Use of activated carbon as an activator of O2 phase transfer allows you to increase the speed of biocatalytic oxidation of phenol up about 20 %.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>биокаталитическое окисление</kwd><kwd>межфазный транспорт кислорода</kwd><kwd>активаторы межфазного переноса</kwd><kwd>интенсификация массопереноса кислорода</kwd><kwd>гидродинамические условия</kwd><kwd>«челночный» механизм</kwd></kwd-group><kwd-group xml:lang="en"><kwd>biocatalytic oxidation</kwd><kwd>oxygen transport from the gas phase into the water</kwd><kwd>activators of interfacial transport of oxygen</kwd><kwd>the intensification of oxygen mass transfer</kwd><kwd>the role of hydrodynamic conditions</kwd><kwd>«shuttle» mechanism</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">Сульман Э.М., Долуда В.Ю., Матвеева В.Г. и др.
