ABSTRACT:
An asphalt-containing mineral oil is deasphalted by contacting the oil with a liquid hydrogen sulfide deasphalting solvent for a time sufficient to remove a substantial portion of the asphalt from the oil. Utilization of liquid hydrogen sulfide as the deasphalting solvent is capable of giving high yields of deasphalted oil. In contrast to the use of aliphatic solvents for deasphalting, the hydrogen sulfide readily mixes with the heavy feed even at relatively low temperatures.
