In order to produce hydrogen from renewable raw materials supported metal-oxide catalysts based on mono- and bimetallic active component (Cu, Ni, Co, Fe) for the steam reforming of bioethanol (12-16 wt. C2H5OH% in water) are proposed and studied.
The catalysts are characterized using N2 physisorption X-ray diffraction (XRD), transmission electron microscopy (TEM), temperature-programmed reduction (TPR) techniques, N2O decomposition.
The effect of the nature and content of the active component, structural and textural properties of the support on the activity, selectivity and hydrogen production rate of the metal-oxide catalysts has been studied in a wide range of temperatures.
Several copper-containing catalysts for steam reforming of ethanol at low and medium temperatures were developed to produce CO-free hydrogen, which is an important condition for its use in low-temperature fuel cells.
