Mn和Zr助剂对介孔碳负载钴基催化剂费托合成反应性能的影响
Effects of Mn and Zr promoters on the performance of ordered mesoporous carbon supported Co catalyst in Fischer-Tropsch synthesis
摘要
Abstract
Cobalt-based catalysts supported on ordered mesoporous carbon (Co/OMC) were modified with Mn and Zr promoters by the co-impregnation method.The cobalt-based catalysts were characterized by XRD, N2 sorption, H2-TPR, H2/CO-TPD and XPS;the promoting effects of Mn and Zr on the catalytic performance of Co/OMC in Fischer-Tropsch synthesis (FTS) were investigated in a fixed-bed reactor.The results indicate that the addition of either Mn or Zr can greatly reduce the selectivity to CH4 for FTS over Co/OMC.Moreover, Mn as a promoter can enhance the selectivity to C2-4 hydrocarbons and the olefin/paraffin ratio, whereas Zr promotes the dispersion of cobalt species and increases the number of active Co sites, leading to a significant increase in the FTS activity and selectivity to C5+ hydrocarbons.关键词
