Özet

Dry reforming of methane has been studied over Co/ZrO2 catalysts promoted with different metal additives (La, Ce, Mn, Mg, K) aiming to improve the performance of the catalysts and increase their resistance to coking. Scanning electron microscopy studies and different activity levels of the catalysts clearly show that the type of the promoter significantly affected the metal dispersion properties and catalytic performances of Co/ZrO2 catalysts. La-modified catalyst exhibited high stability, but moderate activity. It showed no severe coke deposition. Ce-doped Co/ZrO2 displayed the highest activity among all the catalysts prepared and had a very limited activity loss. © 2010 Elsevier B.V. All rights reserved.
