摘要

Abstract

Amorphous Ni-B/ZrO

catalysts were prepared by coprecipitation-chemical reduction with KBH

aqueous solution

and various crystalline phase ZrO

(amorphous-ZrO

tetragonal-ZrO

and monoclinic-ZrO

) supported Ni-B catalysts were obtained by thermal treatment in 5%H

-N

stream at different temperature.The effect of ZrO

polymorphs and the treatment temperature on the catalytic performance for the CO selective methanation were investigated

and the catalysts were characterized by N

physisorption

Powder X-ray diffraction(XRD)

Temperature-Programmed Desorption(CO-TPD and H

-TPD)

and Differential Scanning Calorimeter(DSC).The treatment temperature affected strongly the crystalline structure of ZrO

and the CO methanation activity and selectivity of the Ni-B/ZrO

catalysts were significantly influenced by the crystalline phase of ZrO

.Of the three forms of ZrO

polymorphs(amorphou-ZrO

tetragonal-ZrO

and monoclinic-ZrO

)

the amorphous-ZrO

supported nickle catalyst showed highest CO methanation activity

attributing in large part to the largest specific surface area and the optimum CO/H

absorption intensity of the Ni-B/amorphous-ZrO

catalyst.
