Three experimental runs were completed on the catalyst zone study at conditions of 400/sup 0/C (752/sup 0/F), LHST of 1.9 h, 10.3 MPa (1500 psig), with equal amounts of catalysts in the top and bottom zones and processing a 10% SRC in process solvent. The first run contained a commercial Ni-Mo catalyst in both zones and will serve as a reference base. The two following runs contained the Ni-Mo catalyst in the top zone but contained Co-Mo catalyst and Ni-W catalyst in the bottom zones, respectively. Nitrogen removal data indicated a rapid loss of catalyst activity during the first 42 hours of the experiments and some recovery of activity in the last 30 hours. The H/C atom ratios varied little between the experiments, but the reference run using all Ni-Mo catalyst was somewhat better for nitrogen removal than the Ni-Mo plus Co-Mo. The first phase of the project addressing temperature zoned reactors was completed. 2 figures, 2 tables.
