The invention relates to a method for generating hydrogen, to a system for carrying out said method, and to pourable bodies for use in said system. When generating hydrogen by catalytically splitting organic hydrogen sources such as alcohols, carboxylic acids, aldehydes, and carbohydrates, the required purity of the hydrogen is ensured by way of a membrane-independent principle of the method. The hydrogen should be produced cost-effectively and in high purity. It should be possible to use the systems in a decentralized manner and it should have a capacity that is adapted to the raw material levels. This problem is solved in that magnetically manipulatable pourable bodies (1), which carry a catalyst (4) that is active during splitting and can store hydrogen, are conducted in a cycle due to the action of exterior magnetic fields, comprising the following phases: residence of the pourable bodies in a reactor vessel, which is supplied with organic hydrogen sources in the fluid state, under pressure, temperature and concentration conditions of the catalytic splitting, and subsequently under pressure, temperature and concentration conditions of the hydrogen storage, transferring the pourable bodies by means of exterior magnetic fields, while sealing them with respect to the reactor vessel, into a discharge container, residence of the pourable bodies in the discharge container under pressure and temperature conditions of the release of the stored hydrogen, and removal of the released hydrogen from the discharge container and recirculation of the pourable bodies (1) into the reactor container. The invention can be applied to the generation of hydrogen from the raw materials mentioned above. |
