    Abstract: Low sulfur fuel oil is prepared by distilling an asphaltcontaining petroleum fraction to obtain a vacuum gas oil and vacuum residuum. The vacuum gas oil is passed downwardly with hydrogen through an upper bed of desulfurization catalyst; the residuum fraction is passed upwardly through one or more lower beds of desulfurization catalyst, and the desulfurized effluents are combined. It is found advantageous to pass the distilled fraction down through the desulfurization zone with less residence time and the residual fraction up through the zone to subject it to more back-mixing and turbulence and thereby effecting a longer residence time.

    Abstract: A combination process for treating both municipal refuse and sewage includes the steps of shredding the solid refuse and mixing the shredded material thus obtained with a recycle stream of water resulting from a subsequent coking step to form a slurry; removing noncombustible materials from this slurry; mixing the slurry with sewage sludge and coking the resulting mixture under a pressure sufficient to prevent the vaporization of water, thereby producing grease, clean water and clean coke.
