    摘要： The present invention relates to a process for the preparation of a mixture for producing lithium titanium spinel Li4Ti5O12, having the step of mixing Li2CO3 and TiO2 in a vessel (1) in which at least one oblong element (2) with a first end (2a) and a second end (2b) is arranged such that the first end (2a) points towards an inner wall (1a) of the vessel (1) and is at a distance d from same, wherein the mixing step is carried out by allowing the vessel (1) to rotate and holding the oblong element (2) in its position, with the result that a relative movement takes place between the inner wall (1a) of the vessel (1) and the first end (2a) of the oblong element (2), wherein the distance d is kept constant during mixing. In addition, the invention relates to a process for the preparation of lithium titanium spinel Li4Ti5O12 from a thus-obtained mixture and its use as anode material in rechargeable lithium-ion batteries.

    摘要： The invention relates to a method for depolymerizing materials containing carbohydrates comprising the following steps: (a) treating a material containing carbohydrates with an inorganic catalyst in order to release defined monomeric or oligomeric building blocks from the material containing the carbohydrates; and (b) separating the defined monomeric or oligomeric building blocks produced in step (a) from the rest of the carbohydrate-containing material. Preferably, the inorganic catalyst used in step (a) comprises tectosilicates, phyilosilicates or hydrotalcites and more preferably zeolites or bentonites. The carbohydrate-containing material further comprises preferably LCB and the defined monomeric or oligomeric building blocks are preferably glucoses, xyloses, arabinoses and oligomers thereof. Other aspects of the invention refer to the use of solution promoters in combination with the inorganic catalyst.
