    Abstract: The present invention provides an automotive tire containing from 0.1 wt % to 50 wt % hydrophobic nanocellulose. Hydrophobic nanocellulose may include lignin-coated nanocellulose and/or a chemically modified surface to increase hydrophobicity. The nanocellulose may include cellulose nanofibrils and/or cellulose nanocrystals. The nanocellulose may be introduced into tire components such as inner liner, body ply, sidewall, beads, apex, belts, treads, cushion gum, and textile fabric. The nanocellulose may be obtained from a biomass-fractionation process utilizing an acid catalyst, a solvent for lignin, and water to generate a lignin-containing nanocellulose precursor, followed by mechanical treatment of the nanocellulose precursor to produce the nanocellulose. For example, the nanocellulose may be obtained from the AVAP® process. The tire may further include one or more additional components derived from lignocellulosic biomass. For example, the tire may contain lignin-derived carbon black, lignin-derived antioxidants, biomass-derived silica. The tire may also contain synthetic polymers derived from biomass sugars.

    Abstract: This invention provides processes to convert biomass into energy-dense biomass for combustion, alone or in combination with another solid fuel. Some embodiments provide processes for producing energy-dense biomass from cellulosic biomass, comprising extracting the feedstock with steam and/or hot water to produce an extract liquor containing hemicellulosic oligomers, dissolved lignin, and cellulose-rich solids; separating the extract liquor, to produce dewatered cellulose-rich solids; hydrolyzing the dewatered cellulose-rich solids, thereby removing a portion of the cellulose, to produce intermediate solids (with higher energy density) and a hydrolysate; drying the intermediate solids to produce energy-dense biomass; and optionally recovering fermentable sugars from the hydrolysate. The energy-dense biomass may be pelletized into biomass pellets, which may have a similar energy density as torrefied pellets from wood. The hemicellulosic oligomers may be further hydrolyzed to produce additional fermentable sugars. The fermentable sugars may be fermented to ethanol or another product.
