The present invention relates to a method for preparing a composition comprising one or more omega-3 fatty acid salt(s), the composition obtainable or obtained by this method, and also the use of this composition for the preparation of foodstuffs, food supplements or pharmaceutical products.

The invention discloses a method for producing bio-fuel (BF) from a high-viscosity biomass using thermo-chemical conversion of the biomass in a production line (10) with pumping means (PM), heating means (HM) and cooling means (CM). The method has the steps of 1) operating the pumping means, the heating means and the cooling means so that the production line is under supercritical fluid conditions (SCF) to induce biomass conversion in a conversion zone (CZ) within the production line, and 2) operating the pumping means so that at least part of the production line is in an oscillatory flow (OF) mode. The invention is advantageous for providing an improved method for producing biofuel from a high-viscosity biomass. This is performed by an advantageous combination of two operating modes: supercritical fluid (SCF) conditions and oscillatory flow (OF).

This disclosure provides for processes to form a porous crosslinked polyphenoxide resin, using a templating process which can increase the porosity, pore size, active sites, and the like of the resin, as compared with a non-templated crosslinked polyphenoxide resin. The process includes contacting a phenol or polyphenol compound with formaldehyde and an aqueous base in the presence of a basic particulate template to form a templated crosslinked polyphenol resin. The templated crosslinked polyphenol resin can then be contacted with an aqueous acid to remove the basic particulate template and form a porous crosslinked polyphenol resin. This porous crosslinked polyphenol resin can subsequently be contacted with a metal-containing base to form a promoter for acrylate and acrylic acid formation from CO.sub.2 and ethylene coupling.

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.
