Catalytic reaction of carbon dioxide with methane on supported Co/Mo catalysts

In this work the reforming of methane with carbon dioxide has been investigated at 773 K on supported Mo-Co/ Al2O3 catalysts with different loading 1%, 5% and 10 %. of Mo. The catalysts were characterized by XRD and TEM methods before and after the reaction. The results revealed that 10%Co/Al2O3 had the highest conversion of CH4 and CO2 and highest syngas formation rate among the mentioned catalysts. In addition, the mentioned catalysts characterization before and after the reaction showed no differences

Pure Ni-Based and Trimetallic Ni-Co-Fe Catalysts for the Dry Reforming of Methane: Effect of K Promoter and the Calcination Temperature

This work investigates the effect of the Potassium promoter and the calcination temperature on the catalytic activity in the dry reforming of methane reaction and compares the performance of the Ni, Co, Fe–Al2O3 trimetallic catalysts with the reference Ni–Al2O3. Although higher activity was achieved with the Ni–Al2O3, trimetallic catalysts resulted in a more favorable CO/H2 ratio and considerably better coke resistance. Higher calcination temperature led to the increase in coke formation which caused the sintering of the catalysts. Promoting samples with 0.5%K in order to improve the coke formation resistance, reduced the catalytic activity
