Abstract: A method for detecting a degree of hydrogenation of a liquid comprises one or more liquid hydrogen carriers, which can be hydrogenated, comprising: detecting a material property of the liquid and determining the degree of hydrogenation of the liquid on the basis of the detected material property of the liquid.

Abstract: An arrangement for the advantageous construction of a hydrogen filling station. A special chemical substance class, which is called a Liquid Organic Hydrogen Carrier (LOHC), is dehydrogenated and the hydrogen produced is pressed into the tank of a vehicle by compression. LOHCs have almost twice the quantity of hydrogen per liter compared with a 700 bar tank, but are, however, even stored at ambient temperature and ambient pressure.

Abstract: A method for separating technical and biological polymers by generating two liquid phases using an added gas or an adjusted temperature. The separated polymers are obtained in solution with a high degree of purity. Complete separation can be achieved by subsequently performing liquid chromatography during which the corresponding trace component irreversibly adheres to the column while the other trace component is not retarded.
