Three experimental runs were conducted as part of the temperature zoned reactor study. The first experimental run was for familiarization and corrective purposes only. No data were taken. The two subsequent experimental runs consisted of operations at 400/sup 0/C (752/sup 0/F) in the bottom zone of each reactor and 400/sup 0/C (752/sup 0/F), respectively. The reference catalyst was Armak KF-153-S, an NiMo commercial catalyst. The reference liquid was a 15 wt % mixture SRC in a coal liquefaction process solvent. The liquid volume hourly space time across both reactor zones was 1.9 h with a 20 to 80% space time distribution between the top and bottom zones, respectively. The duration of each experiment was 72 h. Of course the reactor with the higher temperature in the top zone demonstrated increased hydrodenitrogenation. Metals from the coal liquid tended to accumulate in the middle sections of the reactors rather than at the entrance or exit. Also, within a single catalyst pellet the metals accumulated near the outer edge. The high temperature zone showed more metals deposition than found in the low temperature zone. Only partial analyses have been completed on the product liquids and catalysts. 4 tables.
