Этанол является одним из перспективных источников водорода (синтез-газа), в том числе в различных приложениях энергетики. Получение синтез-газа из этанола возможно различными путями, например, такими, как паровая и паровоздушная конверсия, которые являются эндотермической и термонейтальными реакциями соответственно. Контроль и управление тепло- и массопереноса при протекании указанных реакций является важной задачей, что может быть решено за счет использования катализаторов на теплопроводящих металлических подложках. В данной работе представлены результаты изучения физико-химических свойств Pt-, Rh-, Pd-, Ru-, Ni-, Co-содержащих структурированных катализаторов, нанесенных на FeCrAl сетчатый носитель, исследованных в процессах паровой и паровоздушной конверсий этанола. Среди испытанных образцов наибольшую эффективность в процессах паровой и паровоздушной конверсий этанола проявил рутениевый катализатор, обеспечивая равновесный состав продуктов без видимых признаков зауглероживания.

Ethanol is one of the promising sources of hydrogen (synthesis gas), including in various energy applications. The production of synthesis gas from ethanol is possible in various ways, for example, such as steam and steam-air conversion, which are endothermic and thermoneutal reactions, respectively. Control and management of heat and mass transfer during the occurrence of these reactions is an important task, which can be solved through the use of catalysts on heat-conducting metal substrates. This paper presents the results of a study of the physicochemical properties of Pt, Rh, Pd, Ru, Ni, Co-containing structured catalysts deposited on a FeCrAl mesh support, studied in the processes of steam and steam-air conversion of ethanol. Among the tested samples, the ruthenium catalyst showed the greatest efficiency in the processes of steam and steam-air conversion of ethanol, providing an equilibrium composition of the products without visible signs of carbonization.
