A simple preparation method for barium hexaalurninate-based catalysts to be used in catalytic combustion is described. Morphological and physico-chemical characterization data are given for Ba-Al-O (withBa/Al=l/lL) andfor Ba-Mn-Al-O (with Ba/Mn/Al=1/0.5/11.5; l/1/11; l/2/10) samplescalcined at diffe
The oxidation of methane has been studied in the temperature range 475 C Β£ T Β£ 660 C isothermally using Mn-substituted barium hexaaluminate catalysts. The solid material was characterized by BET, XRD and TPD of oxygen. Reproducible oxidation rates are provided and the effects of varying both methane
