Further analyses of the liquid products and catalyst samples of runs CZA-CZF were completed. Experimental conditions of these runs were 400/sup 0/C (752/sup 0/F), 10.3 MPa (1500 psig) and a liquid volume hourly space time of 1.9 h. The catalysts were equally divided between the two zones. The overall reproducibility of this experimental study was documented in runs CZA and CZF, meant to be replicates, in that their nitrogen removal and H to C atomic ratios were similar. The ASTM D-1160 vacuum distillations of representative liquid products revealed that the Ni-Mo and Co-Mo catalysts produced higher hydrocracking activities than did the Ni-W catalyst. Coke contents of spent catalysts range from 20 to 27 weight percent, and generally more coke was present in the top zone of the reactors. The three catalyst types had similar coke contents. Upon oxidative regeneration, from 85 to 93 percent of the original pore volumes and surface areas were recovered. The Ni-W catalyst showed the greatest loss of pore volumes and surface areas upon deactivation. Furthermore, this catalyst revealed a lower percent of recovery upon regeneration. 2 figs., 5 tabs.
