英文摘要 | ni/hzsm-5 and ni/mcm22 catalysts with different ni loadings were prepared by impregnation method and evaluated for aqueous-phase reforming (apr) reaction of xylitol at 240 degrees c and 4 mpa. effects of ni loadings on the xylitol conversion and pentane selectivity of the catalyst was investigated. the results showed that the catalytic activities of the two ni/hzsm-5 and ni/mcm22 catalysts both increased with increasing ni loading in the range of 0-2%. and then decreased as ni loading further increased to 4%. maximum pentane yields of 91% and 95% could be obtained over 2%ni/hzsm-5 and 2%ni/mcm22, respectively. 2%ni/hzsm-5 deactivated obviously after five recycle runs, while 2%ni/mcm22 still kept excellent activity with the pentane yield of 90-95%. the catalysts with different ni loading were characterized by bet, h-2-tpr and nh3-tpd techniques and the used selected 2%ni/mcm22 and 2%ni/hzsm-5 catalyst were also characterized by xrd, ftir and tg. the characterization results revealed that 2%ni/mcm22 and 2%ni/hzsm-5 have similar amounts of ni active sites, while the 2%ni/mcm22 has larger surface area, more mesopore and less strong acid sites than the 2%ni/hzsm-5. moreover, partial dealumination and coke formation of the used 2%ni/hzsm-5 catalyst were found. all these factors resulted in the deactivation of 2%ni/hzsm-5 after five recycle runs.
