摘要: Abstract The effects of carbon dioxide content on the catalytic performance and coke formation nickel catalyst supported mesoporous nanocrystalline zirconia with high surface area pure tetragonal crystalline phase were investigated in methane reforming dioxide. samples characterized by XRD, BET, TPR, TPO, TPH, TEM, SEM techniques. prepared showed a structure narrow pore size distribution. obtained results revealed that increase CO2 increased conversion stability significantly reduced deposition. TPH analysis several species different reactivities toward hydrogenation deposited spent catalysts employed under contents.
