Abstract

Ethanol is one of the promising sources of hydrogen (synthesis gas), in particular, in various power engineering applications. Synthesis gas can be produced from ethanol by various methods, such as steam and autothermal reforming, which are endothermic and thermoneutral reactions, respectively. Control and management of heat and mass transfer during the occurrence of these reactions is an important task, which can be solved by using catalysts supported on heat-conducting metal substrates. This paper describes results of studying the physicochemical properties of FeCrAl gauze-supported Pt-, Rh-, Pd-, Ru-, Ni-, and Co-containing structured catalysts tested in the steam and autothermal reforming of ethanol. Among the tested samples, the highest efficiency in the steam and autothermal reforming of ethanol is exhibited by the ruthenium catalyst, which provides an equilibrium composition of the products without visible signs of carbonization.
