Development of Unique Catalysts for Hydrodenitrogenation of Coal-Derived Liquids. Annual Report, September 15, 1978-September 14, 1979

Description: Preliminary results from decahydroquinoline hydrodenitrogenation runs show that Bronsted acidity by itself will not catalyze carbon-nitrogen bond scission. The C-N bond cleavage must therefore be catalyzed by an active site, which consists of a transition metal ion in close proximity to an acid site. It appears that hydrodenitrogenation requires both an acidic and a basic site for the Hoffman E/sub 2/ elimination reaction to occur. Several catalysts have been prepared and tested, including Bron… more

Development of Unique Catalysts for Hydrodenitrogenation of Coal-Derived Liquids. Annual Report, September 15, 1979-September 15, 1980

Description: Hydrodenitrogenation of quinoline and decahydroquinoline has been studied employing several catalysts: Bronsted and Lewis acid catalysts without metal, and silica-alumina, ..gamma..-alumina and magnesia impregnated with molybdenum, tungsten, nickel or cobalt. Our results show that nitrogen removal rate was highest for molybdenum on alumina and tungsten on silica-alumina or alumina catalysts. Nitrogen abstraction using ..gamma..-alumina support is considerably faster than with magnesia support. … more
