During the hydrodeoxygenation of dibenzofuran on a prefulfided NiMo/Al/sub 2/O/sub 3/ catalyst at 360/sup 0/C and 7.0 PMa, replacement of H/sub 2/ by a 50:50 mixture of NH/sub 3/ and H/sub 2/ for one hour caused a marked decrease in activity, but when this was followed by a return to pure H/sub 2/, catalyst activity improved 140%. This slowly dropped, but even 122 hours later, catalyst activity was 20% greater than before exposure to ammonia. This interesting lead is being explored in a variety of ways. 3 figs.
