Abstract
A process for the mobilization and extraction of organic matter such as kerogen from solids such as oil shale using ionic liquid. An ionic liquid is a salt in the liquid state which has a melting point below 200° C. The process may be carried out in a subsurface reservoir or at the surface.
Claims20
A process for extracting organic matter insoluble in dichloromethane, toluene and hexane from solids, the process comprising:
- combining organic-matter-containing solids and an ionic-liquid-enriched solvent comprising an ionic liquid such that organic matter from the organic-matter-containing solids is transferred into the ionic-liquid-enriched solvent to form a liquid phase comprising the ionic-liquid-enriched solvent and transferred organic matter;
- separating the liquid phase from the solid phase;
- and
- recovering the organic matter from the liquid phase.
The use of a moisture-stable ionic liquid for solubilisation or mobilization of an organic fraction which is insoluble in dichloromethane, toluene and hexane and which is thermally convertible into petroleum products.
