During the last quarter a simple batch reactor test was developed for screening catalysts in terms of their initial activities. The results of replicant tests indicate that the variability in the experiment is sufficiently low that real distinctions can be made among the various catalysts. Only those preparations which appear promising in the batch experiment will be subjected to further testing. Five runs were completed in the continuous unit. These included a brief process variable study on a new feedstock designated FSN-30, a thermal (noncatalytic) run, and deactivation runs on three catalysts. The most extensive deactivation run was a 500+ hour run on a commercial cobalt molybdate catalyst, AMOCAT 1A. The purpose of this run was to provide a basis for comparison with catalysts prepared in the laboratory. AMOCAT 1A has seen service in HRI's CTSL pilot plant and more recently as a first stage catalyst at Wilsonville. It is believed to be superior to nickel molybdate catalysts for service at high temperatures. A chromia-alumina catalyst performed very poorly in both the batch and continuous units, but a CoMo/chromia-alumina catalyst exhibited specific activities roughly comparable to the commercial catalyst. The deactivation curve for the chromia-alumina based catalyst appeared similar to that of the commercial catalyst for the duration of the 200 hour experiment. 11 refs., 5 figs., 14 tabs.
