Abstract: A method of monitoring renewable carbon in fuel streams in a refinery or blend facility while co-processing a bio-feedstock with a fossil feedstock or blending a renewable product with a fossil product wherein the method provides for quantification of renewable C14 carbon content to adjust the total renewable content to a targeted renewable content in situ while lowering the limit of detection.

Abstract: The present disclosure provides a process for upgrading solid biomass feedstocks into more useable products. The process includes introducing a solid biomass feedstock, a liquid carrier, a slurry hydrocracking catalyst to a slurry hydrocracking zone in the presence of hydrogen and under slurry hydrocracking conditions to produce a slurry hydrocracking effluent comprising lighter hydrocarbonaceous products; wherein the liquid carrier is a hydrocracking recycle stream taken only from the slurry hydrocracking effluent; wherein the solid biomass feedstock and liquid carrier are combined upstream of the slurry hydrocracking zone to form a combined feed; the combined feed subsequently being introduced to the slurry hydrocracking zone.
