The report gives results of a program to develop an improved demetallization catalyst so that residuum with high-sulfur and high-metals content could be desulfurized economically. Twenty-eight catalysts were prepared, representing a number of combinations of supports and promoters. Impregnating 20 x 50 mesh granulated activated bauxite with promoters provided the necessary catalytic activity and resistance to poisoning. The residua that were demetallized were Tia Juana, Bachaquero, and Gach Saran vacuum residua. Indications are that these residua can be economically desulfurized to 0.5 weight percent sulfur fuel oil. (Modified author abstract)
