n(H2O)∶n(Al)对Ni-W催化剂低温煤焦油加氢性能的影响
Effects of n(H2O) ∶ n(Al) of Ni-W Catalyst on Catalytic Hydrogenation Properties of Low Temperature Coal Tar
摘要
Abstract
Slurry hydrogenation catalyst with TiO2-AlOOH as the composite carrier and Ni and W as active components were prepared by a complete liquid phase method.The effect of n(H2O) ∶ n(Al) on the structure and catalytic properties of Ni-W catalysts were investigated and the catalysts were characterized by XRD,BET,NH3-TPD and so on.The fraction distribution and composition of raw materials and products were analyzed by GC-MS,TG and ultimate analylzer,the results show that the content of light component,the hydrodesulfurization (HDS)activity and the n(H) ∶ n(C) in the products are the highest when n(H2O) ∶ n(Al) is 75 in the catalysts.It indicates that Ni-W catalyst withn(H2O) ∶ n(Al) 75 has better hydrogenation effect on coal tar hydrotreating than that of the other value of n(H2O) ∶ n(Al).关键词
