Separation of kerogen from green river oil shale

Abstract

The complex analysis of the chemical composition and technological properties of oil shale from the Green River formation was carried out. The technical characteristics and granulometric composition of test samples and the element compositions of the mineral and organic matters of shale rocks were determined. The structure of organomineral aggregates formed upon the crushing of shale rocks was studied by electron microscopy. Based on the experimental data, a procedure was developed for the separation of kerogen from the oil shale by physicochemical processing.
