Several catalysts were analyzed and the reactor EN-1 was redesigned to accommodate zonal bed experiments. In analysis of catalysts directed toward coke deactivation mechanisms, several observations were made: (1) coke accumulates rapidly during the first thirty hours of oil contact; (2) HDN and hydrogenations activities closely parallel the average coke content in the reactor bed; (3) pore size distributions of used catalysts remain the same shape as those of freshly sulfided catalysts; (4) the most frequent pore diameter decreases with increasing coke content; and (5) a linear relationship between pore volume and coke content was observed. In experiments to assess the effect of organic metals addition, titanocene dichloride added to the SRC oil resulted in reactor plugging. The coke content of spent catalysts revealed a linear relationship with titanocene addition. Nearly complete removal of the organometallic compound was achieved with accumulation observed by catalyst deposits and in the restricted sections the material of plugging.
