A series of activated carbon (AC) supported nickel oxide (NiO) catalysts were prepared by aqueous reduction preparation methods with nickel nitrate as a precursor. The effects of preparation procedure and reducing agent on catalyst structure and catalytic property were investigated. Based on the inf
Nickel-zeolite Y of various parent cation types, NiNa-A and NiNa-M were prepa'red. The reducibilities of nickel ions in these zeolites were evaluated by hydrogen consumption measurement. The nickel ions were reduced markedly by hydrogen in NiCa-Y, NiSr-Y and NiBa-Y in contrast to that of NiNa-Y, whe
The dispersion states of reduced nickel on zeolites and their activities were studied on a series of nickel-zeolites A, X, Y and nickel-mordenites. The dispersion of nickel was affected by the types of zeolite support, and increased in the order; NiNa-Y < NiNa-X < NiNa-M NiNa-A. The reduced nickel w
