Development of a process for producing an ashless, low-sulfur fuel from coal. Volume IV. Product studies. Part 6. Hydrodenitrogenation of a coal-derived liquid. [Nalco 72-4710B, Nalcomo 474, Nalco 72-4710A, MoO/sub 3/--CoO catalysts]
An experimental apparatus was constructed to perform hydrodenitrogenation studies by catalysis of ash-free coal-derived liquids. Catalyst deactivation was observed at a reactor operating temperature of 800/sup 0/F and after a reduction in the reactor operating temperature. Data were correlated using a second order rate expression. Activation energies of 28,000, 32,700 Btu/lb. mole (+-3000 Btu/lb. mole) were found for Nalco 72-4710B, Nalcomo 474, and Nalco 72-4710A over the temperature range of 600 to 750/sup 0/F. The activation energy for denitrogenation over Nalcomo 474 between 750 and 800/sup 0/F was 12,300 (+-9300) Btu/lb. mole. The rate of denitrogenation was found to be proportional to the total reactor pressure between 650 and 700/sup 0/F over the pressure range of 500 to 1500 psig. Changes in the hydrogen rate over the range of 1500 to 20,000 SCF/bbl had little effect on the rate of denitrogenation. The rate of denitrogenation was found to be independent of the size of the most frequent catalyst pore radius over the range of 25 to 33 angstroms. (auth)
