Abstract: The invention relates to a structured catalyst for catalyzing steam methane reforming reaction in a given temperature range T upon bringing a hydrocarbon feed gas into contact with the structured catalyst. The structured catalyst comprises a macroscopic structure, which comprises an electrically conductive material and supports a ceramic coating. The macroscopic structure has been manufactured by 3D printing or extrusion and subsequent sintering, wherein the macroscopic structure and the ceramic coating have been sintered in an oxidizing atmosphere in order to form chemical bonds between the ceramic coating and the macroscopic structure. The ceramic coating supports catalytically active material arranged to catalyze the steam methane reforming reaction, wherein the macroscopic structure is arranged to conduct an electrical current to supply an energy flux to the steam methane reforming reaction. The invention moreover relates to methods of manufacturing the structured catalyst and a system using the structured catalyst.

Abstract: A magnetic coupling includes an inner rotor (11) and an outer rotor (9) which at least partly surrounds the inner rotor (11). These rotors (11, 9) each are formed of magnetic material (18) and are coupled to one another by way of magnetic forces. The inner rotor (11) and/or the outer rotor (9) contain powdery, magnetizable material (18). The powdery, magnetizable material (18) is magnetized at a side lying opposite the other rotor at several locations distributed over the periphery.
