Preliminary studies of the catalytic hydrodeoxygenation (HDO) of dibenzofuran at 360/sup 0/C and 7 to 14 MPa have revealed new features of this reaction. Surprisingly, over a presulfided Ni-Mo/Al/sub 2/O/sub 3/ catalyst, as much as 75% of the products are C/sub 5/ to C/sub 7/ single ring compounds. This behavior is markedly different from the analogous hydrodesulfurization of dibenzothiophene, in which double ring C/sub 12/ products predominate. Differences were also found compared to hydrodenitrogenation reactions since removal of H/sub 2/S from the system increased reactivity rather than decreasing it. Higher partial pressures of water enhance the selectivity to isomerization products. The HDO rate is a strong function of hydrogen partial pressure. 2 refs., 11 figs.
