Five catalysts were analyzed for pore size distributions to characterize their properties for selection for future experimentation. Also, several coal liquid feedstocks were obtained and were analyzed in preparation for future studies. Four experimental runs were conducted in the Catalyst Life Test Unit using a 30 wt % SRC in process solvent mixture. These runs were conducted using a Shell 324 catalyst (NiO-MoO/sub 3/) at a temperature of 399/sup 0/C (750/sup 0/F) and a pressure of 13.9 MPa (2000 psig). The purpose of these runs was to obtain conditioned catalysts in order to assess the coking and deactivation response. Hydrodenitrogenation and hydrogenation of the catalysts decayed over the interval of study of these four experimental runs. Experimentation time was from 1 up to 160 hours of oil-catalyst contact. These conditioned catalysts have not yet been analyzed. A controlled experiment is being designed to test the catalyst activity decay caused by organometallics in coal liquids. The experimentation is being prepared to test a 400 ppM of titanocene doctored SRC light oil. This experiment will be conducted in the early part of the following quarter.
