Abstract: A method of making alkanes from lignocellulosic sources of C5 and C6 sugars. Suitable biomass feedstocks are converted into alkane-based fuels such as diesel and jet fuel blendstocks. Sugar monomers from the feedstocks are converted to chloromethylfurfural (CMF) with a levulinic acid (LA) byproduct. The CMF and LA are converted to ethyl levulinate (EL) and hydroxymethylfurfural (HMF), which are then combined into longer chain molecules via aldol condensation reactions. The condensation products are partially or fully saturated by mild hydrotreating, followed by deoxygenation to form alkanes with boiling ranges suitable for use as liquid fuels.

Abstract: A method for the preparation of metallic salts of fatty acids comprising the steps of: (a) reacting alkali hydroxide with a fatty acid in a saponification reaction to form an alkali soap; (b) reacting the alkali soap with an aqueous metallic salt solution in a double decomposition reaction to cause the production of metallic fatty acid salt; (c) performing at least one cycle of an alternating alkalinization-acidization reaction by adding an aqueous alkali hydroxide solution to the metallic fatty acid salt to raise the solution pH, followed by adding an acidic aqueous salt solution contain the same metal ions to lower the solution pH. High purity metallic salts of fatty acids can be obtained without a solvent washing step and the metallic fatty acid salts prepared from this invention can be effectively used as photolyzing agent to initiate and/or accelerate the photo-degradation of plastics.

Abstract: This invention relates to a process of preparing Cocoa Butter Equivalent (CBE) from Chinese Vegetable Tallow (CVT) and to the product prepared. Crude CVT is first subjected to a semi-refining process comprising an alkali treatment, a water wash and an adsorption step. The semi-refined CVT is subjected to a single step fractional crystallization under controlled conditions. After removal of the solvent from the crude CBE found in the mother liquor after filtration, the crude CBE is subjected to a steam distillation process, addition of antioxidants and a final filtration. The resulting product meets all of the criteria necessary for Cocoa Butter Equivalent.

Abstract: A process for the continuous production of fatty acid soaps by reaction with solid metal oxides, hydroxides, hydrogen carbonates and carbonates of Mg, Ca, Ba, Pb, Al, Zn, Co, Fe, Cd and Zr, in which the fatty acids are subjected to a rotational movement by mechanical transport and the metal compounds are subjected to rotation in the opposite direction by mechanical transport, the two reactants are combined in the reaction zone of a tube reactor and are reacted in 0.5 to 50 seconds.

Abstract: A continuous process for preparing a metallic soap by a double decomposition process is disclosed, in which an aqueous solution of an alkali soap and an inorganic metal salt are separately fed directly on the surface of the rotating impeller of a mixer to instantaneously mix them together and the resulting metallic soap aqueous slurry is discharged out from the mixer without delay. Metallic soaps free from contamination with unreacted starting materials or by-products can be continuously obtained using small-sized reactor vessels with a reduced energy.
