The catalytic hydrodeoxygenation (HDO) of dibenzofuran on a presulfided NiMo/sub g/amma/Al/sub 2/O/sub 3/ catalyst was examined. Based on the reaction intermediates identified in the present study, a reaction network for the removal of oxygen from dibenzofuran has been established. In view of the failure to detect certain key reaction intermediates an approximate network has been proposed for kinetic analysis. Using the approximate network the effects of temperature in the range 616-649K, hydrogen pressure in the range 6.89-13.78 MPa and initial concentration of dibenzofuran in the range of 9.78*10/sup -5/ - 21.39*10/sup -5/ g mol/g oil were examined upon the individual steps. The removal of oxygen from dibenzofuran under the above conditions proceeded via direct oxygen extrusion without hydrogenation of the adjacent benzene rings as well as through the formation of hydrogenated intermediates, with the catalyst showing selectivity towards the latter mode of oxygen removal. 18 refs.
