Process for treating oil shale

Patent:

Abstract

A process for treating oil shale is characterized in that the shale is first finely ground, then heated in the presence of steam in a high-pressure retort at 1 to 50 atmospheres pressure at a temperature of 200/sup 0/ to 450/sup 0/C and then with large amounts of water with or without materials forming emulsions with water or with oil. Solution medium suitable for bitumen or paraffin is beaten up in a rapid hammer mill until all or most all of the oil or bitumen is emulsified. The emulsion is separated by filter-pressing and centrifuging from the solid shale residue and the oil or bitumen is again separated from the emulsion medium by heating, acidulating, standing, or centrifuging, and then in known ways is further separated, refined, and worked up.
