Acid treatment of kerogen-agglomerated oil shale
Patent
·
OSTI ID:5434822
This patent describes a method of upgrading kerogen-agglomerated oil shale. It comprises: contacting oil shale with a two-phase mixture comprising an added organic liquid and water to form kerogen-rich agglomerates and mineral-rich particles; separating the kerogen-rich agglomerates from the mineral-rich particles and water utilizing at least one screen, the screen having a size that prevents passage fa the kerogen-rich agglomerates and allows for passage fa the mineral-rich particles and water, thereby producing solid, kerogen-rich agglomerates, and contacting the solid, kerogen-rich agglomerates with an acid-containing solution having a pH of less than about 3 to form acid-treated, kerogen-rich agglomerates.
