Abstract
In the low-temperature distillation of bituminous shales or similar bituminous materials with high ash content for recovery of oil etc., steam or inert gases are introduced from outside through gas taps arranged in a circle in the retort. By the method used steam is introduced simultaneously in levels higher and lower than the one in which the gaseous and vaporized products are removed from the shale material and in such a manner that the zone of oil formation chiefly will be between the two places mentioned where vapors or steam are introduced into the retort. The patent has one additional claim.
