Blown and stripped biorenewable oils
A method for producing a blown and stripped biorenewable oil is provided. The method may include the steps of (a) heating a biorenewable oil to at least 90° C.; (b) exposing an oxygen containing stream to the heated oil to produce a blown oil having a viscosity of at least 40 cSt at 40° C.; (c) adding a base metal catalyst to the blown oil; and (d) stripping the blown oil from step (c) until the stripped oil has an acid value of from about 1 mg KOH/g to about 20 mg KOH/g; wherein the stripped oil from step (d) has a flash point of at least 220° C.
Photochemical reaction system
According to one embodiment, a photochemical reaction system comprises a CO.sub.2 production unit, a CO.sub.2 absorption unit, and a CO.sub.2 reduction unit. The CO.sub.2 reduction unit comprises a laminated body and an ion transfer pathway. The laminated body comprises an oxidation catalyst layer producing O.sub.2 and H.sup.+ by oxidizing H.sub.2O, a reduction catalyst layer producing carbon compounds by reducing CO.sub.2 absorbed by the CO.sub.2 absorption unit, and a semiconductor layer formed between the oxidation catalyst layer and the reduction catalyst layer and develops charge separation with light energy. The ion transfer pathways make ions move between the oxidation catalyst layer side and the reduction catalyst layer side.

Method for chemical separation of cannabinoids
A method for chemical separation of cannabinoids includes: (i) providing a starting organic solvent solution that contains a mixture of cannabinoid acids, (ii) using an aqueous basic solution to remove a portion of the cannabinoid acids from the mixture of cannabinoid acids in the starting organic solvent solution by converting the portion of the cannabinoid acids to cannabinoid carboxylate salts that solubilize in the an aqueous basic solution, (iii) separating the aqueous basic solution in (ii) from the starting organic solvent, (iv) combining the aqueous solution from (iii) with new organic solvent to produce a combined solution, (v) acidifying the combined solution to extract the cannabinoid acids from the aqueous solution to the organic solvent, (vi) separating the organic solvent of (v) from the aqueous solution, and (vii) evaporating the organic solvent of (vi) to leave product cannabinoid acids.
Catalytic Conversion of Lignocellulosic Biomass Into Industrial Biochemicals
This invention relates to a method for the conversion of lignocellulosic biomass into ethyl esters of carboxylic acids. Said method consists of treating the biomass material with an oxidizing agent that is incorporated in an solution comprising one or more acids, one or more alcohols and water, and subsequently performing a catalytic reaction at a higher temperature using the same acidic solution into which a larger volume of alcohol is added, in such a way that the catalytic conversion occurs in a medium with a much higher concentration of alcohol, i.e. with a much higher alcohol-to-water wt ratio. Such a method results in relatively high yields of ethyl esters, such as ethyl esters of formic, acetic, and levulinic acids, while producing a low yield of dialkyl ethers, which are unwanted by-products. The concentration of the oxidizing agent in the pre-treatment step is preferably higher than 6.0 wt %. The oxidizing agent is preferably a Fenton or Fenton-type reagent, and most preferably hydrogen peroxide activated by Fe (II), and/or Ti (IV) ions. The alcohol is preferably ethanol, and when ethanol is used, diethyl ether is formed as the unwanted dialkyl ether by-product. Preferably, the biomass material is pelleted before treatment.
Biomass pretreatment with integral fossil fuel blending
A blended homogeneous oil composition and blending method with reduced environmental footprint using a blend of a biomass liquefaction oil derived from solvolysis with an integral fossil-based oil component. The resulting blended product has a reduced capital cost for the blending system and a reduced per barrel costs as compared to a non-blended biomass derived oil composition.
