Process for the sustainable production of acrylic acid

A process for the production of organic acids having at least three carbon atoms comprises the steps of forming an amount of carbon monoxide and reacting the amount of carbon monoxide with an amount of an unsaturated hydrocarbon. The reaction is preferably carried out in the presence of a supported palladium catalyst, a strong acid, and a phosphine. In some embodiments, the unsaturated hydrocarbon is one of acetylene and methylacetylene, and the organic acid is one of acrylic acid and methyl acrylic acid. The reacting step is preferably performed with carbon monoxide produced from carbon dioxide.

Method of separating carbohydrate

Disclosed is a method of separating carbohydrate, including: mixing formic acid with heteropoly acid, chloride or bromide of lithium, magnesium, calcium, zinc, or iron, or combinations thereof to form a mixing liquid. The method also includes dissolving a cellulose biomass by the mixing liquid to form a solution, mixing water and the solution to hydrolyze the cellulose biomass for forming a carbohydrate solution, and mixing an extractant and the carbohydrate solution to extract the formic acid out of the carbohydrate solution. The heteropoly acid, the chloride or bromide of lithium, magnesium, calcium, zinc, or iron, or combinations thereof in the carbohydrate solution is separated out of the carbohydrate solution by ion exclusion chromatography separation to obtain a carbohydrate.

Liquefaction of biomass at low pH

The present invention relates to regulation of the p H of a liquefaction process. Presented is a method for treatment of a biomass feedstock wherein the biomass feedstock is subjected to liquefaction, at a p H of at most 4, by treatment with hot compressed liquid water (HCW) at subcritical and/or supercritical conditions to improve the conversion efficiency. The present invention is also directed to quenching of a liquefaction process according to above, preventing, minimizing or eliminating clogging and/or fouling of sticky biomass components in process equipment during processing as according to above, and to the use of additives in a biomass liquefaction process.
