摘要： A process for desulfurizing vacuum bottoms derived from a residual oil which comprises contacting said bottoms with metallic sodium in the presence of hydrogen, contacting the sludge-containing product thus produced with an aliphatic hydrocarbon, and separating the sulfur and sodium-containing sludge from the hydrocarbon solution of the desulfurized resid. Water washing the separated sludge removes sulfur and sodium, enabling the remaining hydrocarbon portion to be reclaimed.
