Effect of Re addition on the activities of Co/CeO2 catalysts for water gas shift reaction

Catalytic partial oxidation of CH4 over bimetallic Ni‐Re/Al2O3: Kinetic determination for application in microreactor

“…Prior the catalyst testing, preliminary tests were performed to ensure that the selected operating conditions would result in negligible external mass transfer resistance. The total gas flow rate was varied at a constant residence time of 5 3 10 24 g min cm 23 . It was observed that when the gas flow rate was higher than 60 cm 3 min 21 , methane conversion was independent of the gas velocity, indicating the absence of external mass transfer resistance.…”

“…Adding a small amount of Re obviously increased the catalytic activity. 23 Tepamatr et al (2016) recently revealed that adding a small amount of Re to Cu/cerium oxide and gadolinium doped ceria for the watergas-shift reaction resulted in the significantly improved activity of the Cu catalyst. 24 Despite these advantageous effect of Re, no attempt has so far been made on the use of Re as a catalyst promoter over a Ni-based catalyst, particularly for CPOM.…”

“…The activity was noted to significantly increase when Re was added to the catalyst . Chayakul et al () later investigated the effect of adding Re to Co/CeO 2 catalyst on its capability to catalyze the water‐gas‐shift reaction. Adding a small amount of Re obviously increased the catalytic activity .…”

Cod Removal Of An Industrial Effluent Using Nan crystalline Ceria Synthesized By Solution Combustion Method

“…Several methods such as sol-gel, hydrothermal, co-precipitation etc. have been employed for the preparation of nanocrystalline ceria [10][11][12][13]. In the present study, nanocrystalline ceria was prepared by solution combustion method as this method is simple and the product is formed in a short period of time [14].…”
