Five experimental runs were conducted in the newly constructed trickle-bed reactor. The experiments were designed to obtain data on zoned catalyst beds. This new reactor system demonstrated satisfactory performance in temperature, pressure and flow control. High desulfurization and denitrogenation were achieved on both catalysts tested at conditions of 815F, 1500 psig. These catalysts were a CoMo/Al and NiMo/Al. Zoned bed of 50-50 volume percent of the two catalysts tested revealed no advantages with respect to desulfurization, denitrogenation and activity decay. The level of nitrogen removal was initially high, but activity decay was significant over the operational interval of 100 hours. Two experimental runs were completed in the Catalyst Life Test Unit (CLTU) utilizing a liquid containing 50% Synthoil and 50% Raw Anthracene Oil. This fluid has a 0.54 weight percent sulfur and a 1.21 weight percent nitrogen. The catalyst used in this study was a Ni-Mo-Al/sub 2/O/sub 3/ (Shell 324). The objective of the experiments was to demonstrate the effect of diluting the catalyst bed with a small size inert particle to improve gas-liquid contact and reduce channeling. No difference could be distinguished between the use of particle sizes in the range of 0.25 to 1.00 mm diameter. One run was terminated prematurely because the small particles plugged the catalyst support screens. Precipitous catalyst activity decay was noted for both nitrogen and sulfur removal.
