The method for preparing nanofibrillar cellulose comprises —disintegrating (DIS1) fibrous cellulosic raw material to a first disintegration level to a half-fabricate, —transporting (TRANS) the half-fabricate in the first disintegration level in concentrated form to a destination, and —at the destination, disintegrating (DIS2) the half-fabricate from the first disintegration level to the second disintegration level to nanofibrillar cellulose.

A method of treating a biobased feedstock derived from agricultural resources and specifically from the non-distillate products of fermentation-derived renewable fuel and distilled spirit processes. The separation of thermally labile components from biobased feedstocks result in materials that are thermally stable and better suited for subsequent melt processing in a polymer matrix.

The invention concerns a continuous method for treating a lignocellulosic biomass before enzymatic hydrolysis, said method comprising a transfer of crushed then pressed biomass to a step of impregnation by an acid liquor, the impregnated biomass dripping over the area containing the impregnation liquor, then the resulting wet biomass is pressed and sent to a steam explosion step. The impregnation liquor is prepared in a dedicated area from the used liquor from the dripping operation and/or that from the pressing operation, prior to the explosion step. The invention also concerns the facility for implementing the method.

A process for the conversion of a cellulose containing feed comprising the steps of: contacting the cellulose containing feed with a molten salt hydrate and mildly hydrolyzing the cellulose to form a solution of partially hydrolized cellulose, separating one or more components of the partially hydrolyzed cellulose from the solution, converting the separated one or more components of the partially hydrolyzed cellulose in a thermo-catalytic process.

This specification describes a process of producing a monomeric sugar stream ligno-cellulosic biomass without enzymes or acid catalysts. This is accomplished by removing the water soluble C5 sugars from the ligno-cellulosic biomass feedstream, lowering the pH of the C5 solution with little or no addition of an acid, thermally treating the remaining ligno-cellulosic biomass, combining the thermally treated ligno-cellulosic biomass with the low pH C5 solution and then exposing the mixture to an elevated temperature greater than 80° C. for a time sufficient to hydrolyze at least some of the components of the ligno-cellulosic biomass. Preferably, the thermally treated ligno-cellulosic biomass is subjected to a fiber shives reduction step to reduce the amount of long fiber shives.
