Abstract: The invention relates to a method for the preparation of micro- or nano crystalline cellulosic compositions from virgin cellulose containing amorphous and crystalline cellulose phases comprising the following steps: (A) contacting virgin cellulose with a first solvent, characterized in that the first solvent is an aqueous solution comprising 40-65 wt. % ZnCl2 in water, relative to the total weight of the of ZnCl2 and water, (B) dissolving the amorphous cellulosic phase, whereby the amorphous cellulosic phase is preferentially dissolved over the crystalline cellulosic phase, (C) separating the dissolved amorphous cellulose from the crystalline cellulose and preferably step C wherein the obtained micro- or nanocellulose has XRD type I structure, which then can be contacted with a second solvent comprising between 65 and 90 wt. % ZnCl2 in water to produce delaminated cellulose having XRD type II structure.

Abstract: The invention relates to a process for converting a waste FEED material comprising a cellulose containing part and optionally a non-cellulosic part, for example plastic, to useful products said process comprising contacting the waste material with a first molten salt solvent at a first low temperature to dissolve the cellulose, separating non-dissolved components from the cellulose solution, precipitating and separating the cellulose from the used first molten salt solution and carbonizing non-dissolved components at high temperature in a second molten salt solvent comprising the used first molten salt solvent to form solid carbon and hydrogen.

Abstract: The invention relates to a method for the preparation of a hybrid nano-structured composite comprising cellulose nano-particles and metal compound nano-particles, to the nano structured-composite product obtainable by the process and to uses thereof. The method comprises the steps of contacting virgin cellulose with a molten metal salt solvent M1-S and dissoluting the virgin cellulose, optionally exchanging at least part of metal ions M1 with metal ions M2 and converting at least part of the metal ions M1 and/or optional M2 to metal compound nano-particles, precipitating the cellulose nano-particles and isolating the co-precipitated cellulose- and metal compound nano-particles.

Abstract: A method for separating gaseous carbon dioxide from air is proposed by cyclic adsorption/desorption using a sorbent. The method includes the following sequential and in this sequence repeating steps: (a) contacting air with the sorbent to allow gaseous carbon dioxide to adsorb on the sorbent under ambient atmospheric pressure and temperature conditions; (b) isolating the sorbent from the flow-through; (c) inducing an increase of the temperature of the sorbent; (d) extracting the desorbed gaseous carbon dioxide from the unit and separating gaseous carbon dioxide from steam/water; and (e) bringing the sorbent to ambient atmospheric temperature and pressure conditions. The sorbent is a water retaining and/or porous support which before use in the cyclic process has been impregnated or wetted with a solution of a secondary amine compound and the sorbent is loaded by said secondary amine compound by at least 5% by weight.

Abstract: A process is disclosed for converting cellulose to nanocellulose. The process comprises dissolving a cellulose feedstock in an inorganic molten salt solvent medium. The solvent medium is substantially proton free. The solvent medium may contain a proton scavenger. The process is carried out at relatively low temperatures, and requires little input of mechanical energy.

Abstract: 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.
