Abstract: A process for the preparation of fuel grade dimethyl ether from a hydrogen and carbon oxides containing synthesis gas, wherein the synthesis gas is converted to a mixed process gas of dimethyl ether, methanol and water in one or more catalytic reactors in the presence of a catalyst having activity both in synthesis of methanol and methanol dehydration; the mixed process gas is cooled to obtain a liquid process phase containing the produced methanol, dimethyl ether and water and a gaseous process phase containing unconverted synthesis gas and a part of produced dimethyl ether, which process comprises further steps of separating the gaseous phase and liquid phase; passing the liquid phase to a first distillation unit and distilling off a top product stream containing dimethyl ether and methanol and withdrawing a bottom stream containing methanol and water; passing the bottom stream to a second distillation unit and distilling off a methanol containing stream, introducing the methanol into a purge washing unit; washing the gaseous process phase with the methanol in a purge washing unit and withdrawing from the unit a washing stream of dimethyl ether and methanol; converting a part of the methanol in the washing stream to dimethyl ether and water in a catalytic dehydration reactor by contact with a dehydration catalyst; withdrawing from the dehydration reactor a product stream of dimethyl ether, water and unconverted methanol; and combining the top product stream from the first distillation unit with the product stream from the dehydration reactor to obtain a combined product stream of fuel grade dimethyl ether.

Abstract: Nitrogen oxides can be removed from offgases from turbines by a selective catalytic reduction (SCR) with ammonia with greater efficiency than by prior art technique if the ammonia needed for the reduction of the nitrogen oxides is added before the turbine, preferably in a stoichiometric excess compared to the contents of nitrogen oxides in the exhaust gas. One can employ well-known SCR catalysts and advantageously the exhaust gas after the turbine is passed through a layer of SCR catalyst followed by a layer of a combustion catalyst. The latter expediently consists of metal oxides, preferably selected from copper oxide, manganese oxide and chromium oxide, deposited on aluminium oxide, magnesium oxide, silicon oxide or mixtures thereof.

Abstract: A superconductive conductor or cable comprising a core (2), which comprises at least one string of a ceramic, superconductive material, and where the core (2) is encapsulated by a metal cap (1). 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 (2), at least one layer of not sintered, ceramic powder material (3) is provided between the cap (1) and the core (2), which material has a higher sintering temperature than the superconductive material in the core (2). The superconductive core (2) may be sintered for formation of the superconductive ceramics by placing in the tubular metal cap (1) a starting material in powder form, and shaped as a core in the other ceramic powder material and subsequently forging the metal cap (1) with its content, preferably by swaging at an ambient temperature, which is below the sintering temperature of the core (2).

Abstract: A process for preparing urethanes by reacting a solution of a nitrogen-containing organic compound and a hydroxyl-containing organic compound with carbon monoxide in the presence of a ruthenium catalyst. In one embodiment of the process of this invention, the ruthenium catalyst is a halide-free ruthenium catalyst and the rate of conversion and selectivity to urethane is increased by providing a primary amine in the reaction solution. In another embodiment, the rate of conversion and selectivity to urethane is increased by providing a bis-phosphine ruthenium compound as the catalyst.
