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.

Abstract: Provided is a process for hydrocracking normal paraffins into lighter normal paraffins with minimal formation of iso-paraffins. The process comprises hydrocracking a hydrocarbon feedstock comprising normal paraffins under hydrocracking conditions. The reaction is run in the presence of a selected catalyst, e.g., an LTA-type zeolite, with a requisite topology and acid site density. The zeolite has a framework type with voids greater than 0.50 nm in diameter, which are accessible through apertures characterized by a longest diameter of less than 0.50 nm and a shortest diameter of more than 0.30 nm. The reaction conducted in the presence of such a selected zeolite produces an n-paraffin rich product.

Abstract: Provided is a process for hydrocracking normal paraffins into lighter normal paraffins with minimal formation of iso-paraffins. The process comprises hydrocracking a hydrocarbon feedstock comprising normal paraffins under hydrocracking conditions. The reaction is run in the presence of a specific type of zeolite based catalyst which has been found to provide high conversion with minimal iso-paraffin products. In one embodiment, the zeolite is of the framework PWO. The reaction conducted in the presence of the zeolite based catalyst produces an n-paraffin rich product that needs no separation step before being fed to a steam cracker to produce lower olefins.
