Abstract

The present disclosure generally relates to compositions and methods of simultaneously making two unique biointermediates from a single lignocellulosic biomass feedstock, including a hydrophobic biohydrocarbon and a water insoluble hydrophilic cellulosic biopolymer for use in the production of renewable fuels, chemicals, and other carbon neutral materials commonly derived from petroleum and other fossil resources.
