Catalytic desulfurization and denitrogenation. Final report Jun 1972--Jul 1975
The report gives results of a study of catalytic desulfurization and denitrogenation, using thiophene and pyridine as model compounds because they represent some of the less reactive organosulfur and organonitrogen compounds. When thiophene is hydrodesulfurized simultaneously with the hydrodenitrogenation of pyridine (200 to 500C, 4.4 and 11.2 bars pressure, commercial catalysts), the two reactions are mutually inhibitive at lower temperatures. At high temperatures, H/sub 2/S (a hydrodesulfurization reaction product) enhances the hydrodenitrogenation rate. The report proposes mechanisms to explain these observations. In hydrodenitrogenation of pyridine and other heterocyclic nitrogen compounds, the rate may be at least partly governed by the equilibrium of the first step, the hydrogenation of the N-containing ring.
