Process for the Commercial Production of High-Quality Catalyst Material
The present invention describes an improved process for the commercial scale production of high-quality catalyst materials. These improved processes allow for production of catalysts that have very consistent batch to batch property and performance variations. In addition these improved processes allow for minimal production losses (by dramatically reducing the production of fines or small materials as part of the production process). The improved process involves multiple steps and uses calcining ovens that allow for precisely control temperature increases where the catalyst is homogenously heated. The calcining gas is released into a separate heating chamber, which contains the recirculation fan and the heat source. Catalysts that may be produced using this improved process include but are not limited to catalysts that promote CO hydrogenation, reforming catalysts, Fischer Tropsch Catalysts, Greyrock GreyCat™ catalysts, catalysts that homologate methanol, catalysts that promote hydrogenation of carbon compounds, and other catalysts used in industry.

FORMULATION TO SOLIDIFY COOKING OIL OR GREASE AND METHODS OF MAKING AND USING THE SAME
A formulation for solidifying used cooking oil or grease and methods of making and using the same is disclosed. The formulation comprises hydrogenated castor oil, sometimes having a flake morphology. In some embodiments, the formulation has a melting point of between 70 and 80° C. and a density between 0.7 and 1.0 g/L. In some embodiments, the formulation is created by heating castor oil in the presence of a catalyst until at least some of the ricinoleic acid content in the castor oil is reduced to form hydrogenated castor oil in a reaction mixture. The method of using the formulation comprises the steps of mixing the formulation and used cooking oil or grease at an elevated temperature until the formulation completely dissolves into the used cooking oil to form a formulation mixture, and waiting until the formulation mixture cools and solidifies prior to disposal.

CONTINUOUS PROCESSING OF LIGNIN FOR REDUCED SOLVENT USAGE IN REDUCTIVE CATALYTIC FRACTIONATION
Described herein are devices and methods for the efficient and economic generation of lignin monomers from biomass. The provided devices and methods utilize reductive catalytic fractionation with an organic solvent to extract high-quality lignin from biomass and cleave specific lignin bonds to generate valuable lignin monomers with a relatively narrow product slate. Advantageously, the devices and methods described herein utilize solvent recycling, multiple solvolysis chambers with multiple biomass beds and/or physical agitation (e.g., use of a screw extruder) to reduce the amount of solvent required and increase economic efficiency and monomer yield.
