A simple preparation method for barium hexaaluminate-based catalysts to be used in catalytic combustion is described. Morphological and physico-chemical characterization data are given for Ba-Al-O (with Ba/Al=1/12) and for Ba-Mn-Al-O (with Ba/Mn/Al= 1/0.5/11.5; 1/1/11; 1/2/10) samples calcined at different temperatures. The preparation method here proposed provides stable materials with a surface area of 15 m(2)/g after calcination at 1400 degrees C. The structural and morphological properties, ae well as the results of activity tests in methane combustion, compare well with those reported in the literature for samples with the same composition and prepared according to a more complex preparation route.

Abstract

A simple preparation method for barium hexaaluminate-based catalysts to be used in catalytic combustion is described. Morphological and physico-chemical characterization data are given for Ba-Al-O (with Ba/Al=1/12) and for Ba-Mn-Al-O (with Ba/Mn/Al= 1/0.5/11.5; 1/1/11; 1/2/10) samples calcined at different temperatures. The preparation method here proposed provides stable materials with a surface area of 15 m(2)/g after calcination at 1400 degrees C. The structural and morphological properties, ae well as the results of activity tests in methane combustion, compare well with those reported in the literature for samples with the same composition and prepared according to a more complex preparation route.
