    摘要: Process and arrangement for producing tetrahydrofuran from a hydrous butane diol solution contaminated by light volatile, organic compounds, comprising the following process stages: a) Distillative removal (K1) of the light volatile, organic compounds contained in the hydrous butane diol solution 1. b) Dehydrating (R) of the thus prepurified hydrous butane diol solution 3 over an acidic aluminum oxide catalyst. c) One-step or multi-step distillation (K2) of the thus obtained high-tetrahydrofuran fraction 8 for obtaining a pure tetrahydrofuran. In addition, a separation of the water from the hydrous butane diol solution to water contents of from 2 to 70% by weight, particularly 2 to 10% by weight, can take place before the dehydrating of the butane diol.

    摘要: The invention relates to a method and a device for generating hydrogen (5), wherein an input (1) comprising carbon is fed longitudinally through a tube-shaped reaction chamber (Z), together with water steam (2), and is thereby converted by steam reforming, and hydrogen (4) formed during steam reforming is continuously drawn off out of the reaction chamber (Z) through a separating wall (T), said wall being selectively hydrogen-permeable at least in segments, and at a pressure less than the pressure in the reaction chamber (Z) and greater than the ambient pressure, having greater purity than product (5), characterized in that a separating wall (T) is used, the selectively hydrogen-permeability segments thereof being disposed such that a hydrogen partial pressure drop exists over the entire surface of each of such segments between the reaction chamber side and the hydrogen extraction side (W).

    摘要: A process and apparatus for converting starting materials containing hydrocarbon into a hydrogen-rich product gas is disclosed. A raw synthesis gas containing hydrogen (H2) and carbon monoxide (CO) is generated from the hydrocarbon-containing starting materials in a first process step of which at least a part undergoes a catalytically supported water-gas shift reaction to increase the percentage of hydrogen. The water-gas shift reaction is carried out at temperatures between 50 and 200° C., preferably between 60 and 150° C., and at temperatures between 1 and 10 bar, preferably between 1 and 5 bar, in a reactor in which a suitable catalyst is present.
