Pd-based catalysts for combustion of CH 4 have been prepared by wet impregnation methods using BaAl 12O 19 as support and PdCl 2 as metal precursor. It has been found that up to 5% Pd (w/w) can be deposited on the investigated support. Pd adsorption is markedly favoured at high temperature, low acid contents, high Pd initial concentrations and low Cl - content. The effect of the different parameters are explained assuming that Pd deposition occurs via the hydrolisis of the chloro-aquo-Pd complex on basic sites of the support. The prepared samples show good catalytic activity properties in CH 4 combustion.

Abstract

Pd-based catalysts for combustion of CH 4 have been prepared by wet impregnation methods using BaAl 12O 19 as support and PdCl 2 as metal precursor. It has been found that up to 5% Pd (w/w) can be deposited on the investigated support. Pd adsorption is markedly favoured at high temperature, low acid contents, high Pd initial concentrations and low Cl - content. The effect of the different parameters are explained assuming that Pd deposition occurs via the hydrolisis of the chloro-aquo-Pd complex on basic sites of the support. The prepared samples show good catalytic activity properties in CH 4 combustion.
