The use of crystallographic data in formulating models useful in the improvement of MoO/sub 3//Al/sub 2/O/sub 3/ catalysts promoted by Co and Ni is illustrated. The activated forms of existing catalysts were modeled with CoMo/sub 2/S/sub 4/ starting in 1974. This led to the prediction that MoO/sub 3/ loadings higher than those in use at that time should be possible with constructive results. The model was found to be valid in tests of catalysts with various metals loadings for initial resid desulfurization activity, and more extended testing for the desulfurization of light diesel. A separate program started later led to the development and eventual commercialization in 1982 of what are now among the world's most active denitrogenation catalysts. A review of the current status of fundamental research in the area of Mo-based hydrotreating catalysts is discussed and futuristic predictions are addressed.
