A series of boron-modified commercial Ni-Mo/A1203 hydrotreating catalysts have been characterized by IR analysis of adsorbed NO and pyridine and by gas-oil sulfur-and nitrogen-removal activities. Sulfur removal activity was found to correlate with the 1690 cm -1 (Mo(NO)22Γ·) band in the NO adsorption

Ni Mo/A1203 catalysts containing two promoters, fluoride and phosphorus, were studied to learn whether the benefits of both promoters could be combined to produce a superior catalyst. Initially, two series of catalysts differing in the sequence of impregnation of the additives were prepared and test
