Catalysts for upgrading coal-derived liquids. Quarterly report, January 1-March 31, 1982
Construction of a new reactor system incorporating significant improvements was completed, and experimental run ZBF was initiated. This run is part of a set to evaluate reactor beds of zoned and differing catalysts. Only a single, large pore catalyst is presently under test. Catalyst support properties for hydrotreating an SRC oil can be predicted based on a parallel fouling model. The larger pore diameter catalysts with smaller pellet size not only provide lower diffusional resistances, but, just as significant, they can accommodate more coke while maintaining activity. Studies of the effects of titanocene dichloride addition to the feed stock on hydrotreatment indicate the following: (1) an improved hydrotreatment catalyst activity while processing SRC-light oil; (2) a reduction of coke content along the length of the catalyst bed; and (3) ease of the removal of the titanocene dichloride itself in the hydrotreatment operation.
