摘要

A series of Ketjenfine Ni-Mo hydrodenitrogenation (HDN) catalysts has been analyzed by transmission electron microscopy (TEM). The differences in the dispersion and morphology of the catalysts have been evaluated. The TEM data have been used to calculate the number of the accessible active sites and to estimate which type of active sites is present.It has been shown that the HDN activity differences can be explained by the differences in the population of the active sites as well as by the different type of sites present in the catalysts.The newly developed grades,KF 846 and KF 848 have a significantly improved HDN performance over the existing grades.
