Abstract
This work is devoted to the investigation of local raw materials, its preparations processes and
characterization technique of a Cu-Fe-O applied as a catalyst for hydrocarbon (HC) oxidation.
Samples obtained by high temperature solid state method using copper oxide (CuO) and iron
oxide (Fe2O3) and by wet chemical synthesis method using water as a solvent, applying iron
nitrate (Fe(NO3).9H2O) and copper nitrate (Cu(NO3)2.3H2O). In wet synthesis method the thermal
treatment at 100oC and 150oC, water and nitrates removed from the sample, respectively. Three
samples prepared at different quantitative precursor composition that is Fe/Cu = 0.5, 1 and 2 for
each principal procedures. Mixing and calcinations at 850oC for 8hours were the common unit
operations for both preparation routes.
In this work it is demonstrated that, the nature of preparation ways, the structural property of
precursors and the quantitative precursor composition affects the formation of desired phase,
crystal property, size and strain of crystals, microstructure and specific surface area of the
sample; which are among the most relevant physical and chemical properties for the catalytic
activity. The phase identification, structural property and morphology analysis of samples were
characterized by X-ray diffraction and Blaine air permeability apparatus and the samples
prepared by solid state method on a precursor composition of Fe/Cu = 0.5 showed optimized
property.
