Kinetic comparison of Ni/Al2O3 and Ni/MgO-Al2O3 nano structure catalysts in CO2 reforming of methane
The kinetic characteristics of the Ni/Al2O3 and Ni/MgO-Al2O3 catalysts were investigated in CO2 reforming of methane (CRM). The reaction orders (α and β) and the rate constant (k) were calculated using the non-linear regression analysis, in which the sum of the squared differences of calculated and experimental CO2 reforming of m...
متن کاملEffect of K2O on the catalytic performance of Ni catalysts supported on nanocrystalline Al2O3 in CO2 reforming of methane
CO2 reforming of methane (CRM) over unpromoted and potassium promoted Ni/Al2O3 catalysts was studied. The catalysts were prepared by impregnation method and characterized by X-ray diffraction (XRD), N2 adsorption (BET), temperature programmed reduction (TPR), temperature programmed oxidation (TPO) and scanning electron microscope (SEM) techniques. The obtained results showed that addition of K2...
متن کاملInvestigation of the catalytic performance and coke formation of nanocrystalline Ni/SrO-Al2O3 catalyst in dry reforming of methane
In this study, nickel catalysts supported on mesoporous nanocrystalline gamma alumina promoted by various strontium contents were prepared by the impregnation method and employed in dry reforming of methane (DRM). The prepared catalysts were characterized using N2 adsorption (BET), temperature-programmed reduction and oxidation (TPR,) and oxidation (TPDTPO), X-ray diffraction (XRD), and scannin...
متن کاملStructured Ni catalysts on porous anodic alumina membranes for methane dry reforming: NiAl2O4 formation and characterization.
This communication presents the successful design of a structured catalyst based on porous anodic alumina membranes for methane dry reforming. The catalyst with a strong Ni-NiAl2O4 interaction shows both excellent activity and stability.
متن کاملPreparation of Ni-based metal monolithic catalysts and a study of their performance in methane reforming with CO2.
A series of Ni/SBA-15/Al(2)O(3)/FeCrAl metal monolithic catalysts with Ni loadings varying between 3 % and 16 % were prepared, and their structure was characterized by various techniques. The catalytic activity of the catalyst for methane reforming with CO(2) leading to synthesis gas was evaluated using a fixed-bed reactor. The results indicate good catalytic activity of the Ni/SBA-15/Al(2)O(3)...
