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)22÷) band in the NO adsorption
