Abstract

Ce-Zr oxide based metal catalysts were prepared by sol-gel or impregnation method and its structure, activity, and the different carbonaceous species formed during the CH4 dry reforming with CO2 were studied. The catalytic tests showed the temperature dependence on catalytic activity for CeZrNi and CeZrNiMe based catalysts. CH4 conversion was lower than CO2 due to the presence of reverse water gas-shift reaction occurring simultaneously with CO2 reforming of CH4. The highest activity in both CO2 and CH4 conversion was observed over catalyst where the part of Ni was substituted by Rh. The Ni/CeZr catalyst with Ni impregnated on it was lower than CeZrNiRh but higher than sol-gel prepared and CeZrNiCo. This is an abstract of a paper presented at the 2010 Spring National Meeting (San Antonio, TX 3/21-25/2010).
