Abstract
Treatment of a petroleum residuum containing 1.65 pct s with excess metallic sodium (3.1 Mole of na/mole of s) in the presence of hydrogen at 350 deg. C decreases the sulfur content to 0.3 to 0.4 pct. To lower the sulfur content below 0.1 pct requires 6 moles of na/mole of s. Parallel experiments with dibenzothiophene dissolved in decahydronapthalene resulted in >99 pct removal of sulfur to form primarily diphenyl. The rate of desulfurization is inversely proportional to hydrogen pressure and proceeds even in its absence. In the absence of hydrogen, however, char formation is favored.
