Abstract
A method for chemically-upgrading shale-bound kerogen comprises contacting shale-bound kerogen comprising carbon-carbon double bonds with a quantity of alkene species in the presence of an olefin metathesis catalyst. A catalyzed metathetical reaction occurs between the shale-bound kerogen and the alkene species and smaller kerogen-derived molecular species are formed. The smaller kerogen-derived molecular species are recovered.
