Desulfurization with transition-metal catalysis. Quarterly progress report, March 27, 1982-June 27, 1982

Technical Report ·
OSTI ID:5011105

The principal objective of this research is to uncover new reagents and catalysts for upgrading coal-derived fuels by removing undesirable organosulfur, organonitrogen and, if feasible, organooxygen components. During the third quarter of this two-year grant the following studies were initiated or continued: (a) study of the desulfurizing action of nickel, cobalt and copper salts, combined with metal hydrides, on SRC plant liquids, (b) survey of the capability of low-valent nickel reagents to desulfurize, in one step, sulfones and other model organosulfur compounds; (c) development of molybdenum-based desulfurizing agents; and (d) exploration for denitrogenating agents suitable for quinolines and carbazoles. The following progress has been made: (a) nickel salts are superior to cobalt and copper salts in desulfurizing SRC liquids; in a two-step treatment, an SRC liquid was freed of 90% of its sulfur (0.5 to 0.05%); (b) in ethereal solutions vinylic and acetylenic sulfones can be reduced to sulfides by metal hydrides; inclusion of nickel salts gives some desulfurization; (c) some novel butadiene-molybdenum complexes have been synthesized for desulfurization studies; and (d) the treatment of quinoline and carbazole derivatives with nickel and titanium salts, combined with a metal hydride, is being evaluated as a possible denitrogenation procedure.
