CATALYSTS FOR THE HYDRODENITROGENATION OF ORGANIC MATERIALS ABSTRACT OF THE INVENTION The present invention discloses a process for forming a catalyst for the hydrodenitrogenation of an organic feedstock, which includes (a) obtaining a precatalyst comprising cobalt and molybdenum or nickel and molybdenum; (b) adding in a non-oxidizing an atmosphere selected from hydrogen, helium, nitrogen, neon, argon, carbon monoxide or mixtures thereof to the precatalyst of step (a), a transition metal moiety selected from compounds of iridium, rhodium, iron, ruthenium, tungsten or mixtures thereof for a time and at a temperature effective to chemically combine the components: and (c) heating the chemically combined catalyst of step (b) optionally in vacuum to remove residual volatile organic materials. Preferably, a precatalyst of cobalt/molybdenum or alumina is heated between 100° and 500°C in a hydrogen atmosphere with an organometallic moiety of ruthenium, preferably ruthenium carbonyl. The invention further includes the catalysts obtained and the process of hydrodenitrogenation of organic feedstocks including a crude petroleum residue, a petroleum fraction, an oil shale fraction, a tar sands fraction, a coal derived powder, a coal derived liquid or mixtures thereof: The process reduces the amount of hydrogen usually needed to obtain hydrodenitrogenation and more selectively produces aromatic product than saturated organic product.
