Method and apparatus for the hydrolytic separation of cellulose

摘要

A plurality of reactors, which can all be interconnected selectively by way of pipes, are used for the hydrolytic separation of a cellulose-containing substrate so that a stepwise pressure reduction in one reactor is made possible and thus a stepwise pressure build-up in all the other reactors. The steam entering and leaving the reactors is used to produce a fluidized bed of the substrate. A high output with a low specific expenditure of energy is achieved by these measures.
