Title: Method for recovering hydrocarbons from tar sands and oil shales
Inventor: CONAWAY LAWRENCE M
IPC: C10G1/04
Filed: 2000-11-20
Abstract: A method for treating hydrocarbonaceous deposits to recover a petroleum-like hydrocarbon portion and a cleaned particulate substrate portion.  Hydrocarbonaceous ore containing bitumen and/or kerogen is crushed or otherwise comminuted to sand sized particles or smaller. The comminuted ore is mixed with water in a slurry hopper (11) to form a slurry (12), heated to between 60~C and 100~C in a first reactor vessel (14), and blended with oxidant solution (16), preferably hydrogen peroxide. In the presence of the oxidant free interstitial hydrocarbons and those hydrocarbons bound electrostatically to the surface of the substrate are released in an electrophysical reaction. Some of the released hydrocarbons and in particular bituminous and kerogenic compounds are then controllably cleaved by the oxidant in a limited Fenton's reaction to yield organic compounds having lower average molecular weights which are suitable for refining as oil. The cleaned particulate substrate substantially free of hydrocarbon contamination is environmentally suitable for landfill.

Abstract: A device that is used for treating mineral material, in particular material excavated from the ground, has two rollers that rotate in opposite directions. Several elements that are used to convey and reduce the material in the event the particle size is too great are located on said rollers. Particularly brittle and coarse-grained components of the mineral material are reduced by means of elements that are designed to perform a notching action on particles whose size exceeds a minimal size.  Reduction by means of the notching action has been shown to save energy and be less wearing for machines. The elements that perform the notching action can also reduce wood (tree stumps).
