Разработка эффективных катализаторов конверсии шахтного метана в водородсодержащий газ

Abstract

The Ni/Ce[1-x]La[x]O[y] and Ni/Ce[1-x]La[x]O[y]/Al[2]O[3] catalysts (x=0-1) were prepared for the mine methane conversion to hydrogen-containing gas. The influence of the support composition on the physicochemical characteristics of the catalysts and their activity in autothermal reforming of methane (ATR of CH[4]) was studied. It was shown that the dispersion of the Ni active component was enhanced with growth of molar ratio of La in the support composition that leads to the increase in catalyst stability in ATR of CH[4]. The Ni/Ce[1-x]La[x]O[y]/Al[2]O[3] catalysts in comparison to the Ni/Ce[1]-xLa[x]O[y] provide higher H[2] yield: at 850oC it is equal to 65-75%.
