Abstract: A superconductive conductor or cable comprising a core, which comprises at least one string of a ceramic, superconductive material, and where the core is encapsulated by a metal cap. In order to manufacture a conductor or a cable with an encapsulation, and in which it is possible as well during the manufacturing process as under the operation to maintain a controlled atmosphere around the superconductive core, at least one layer of not sintered, ceramic powderous material is provided between the cap and the core, which material has a higher sintering temperature than the superconductive material in the core. The superconductive core may be sintered for formation of the superconductive ceramics by placing in the tubular metal cap a starting material in powderous form, and shaped as a core in the other ceramic powder material and subsequently forgeing the the metal cap with its content, preferably by swaging at an ambient temperature, which is below the sintering temperature of the core.

Abstract: A cooled reactor for exothermic catalytic conversion of gaseous materials, e.g. for the oxo synthesis, for the conversion of hydrogen and nitrogen to form ammonia and for the reaction of carbon oxides with hydrogen to form methanol, comprises a cylindrical pressure shell (10), distributor means (34) for synthesis gas, at least one tube sheet (30) and one or more catalyst beds (20) provided with cooling tubes (38) for the indirect cooling of reacting gas. Each cooling tube (38) consists of an outer tube (4) provided with a heat exchanging outer wall (7); this outer tube surrounds and is coaxial with an inner tube (2) and hence defines an annular space the inner wall of which is provided with perforations (8) to direct the stream of cooling gas, which may consist of or contain components of the synthesis gas, to the annular space and along the heat exchanging wall. There is obtained a very rapid equalization of temperature differences in the catalyst bed, which causes an improved yield and hence makes it possible to decrease the amount of catalyst for a given process.

Abstract: When producing ammonia in a conventional ammonia plant there is obtained a substantially improved process economy by incorporating a fuel cell into the ammonia plant. A gas stream rich in carbon dioxide, obtained during the production of ammonia, is passed to the cathode gas loop of the fuel cell; and/or a purged gas stream emanating from the process plant and containing one or more components usable as fuel for the fuel cell is fed to the anode chamber of the fuel cell. Finally, exhaust gas usable as fuel is passed from the anode chamber of the fuel cell to the front end of the process plant. An improved production of electricity is obtained in the fuel cell; and the stream rich in carbon dioxide formed in the ammonia plant is utilized, whereas normally it is a waste product.

Abstract: A catalytic chemical process is carried out non-adiabatically using as a catalyst a body with two sets of channels throughout the body. One set of channels leads the process fluid towards one of two parallel walls of the catalyst chamber, the other set towards the outer wall, In slits between walls and catalyst heat is exchanged between process fluid and at least one of these walls upon reflecting the process fluid leaving channels of one set and entering channels of the other. The body may be made of alternatingly corrugated and plane sheets using in turn two different orientations for the corrugated sheets. It is preferred that the sheets are arranged orthogonal to the heat transmitting wall(s) and parallel to the overall direction of flow. The method is preferred for endothermic processes, especially steam reforming of hydrocarbon(s).
