    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.
