Abstract:
PROBLEM TO BE SOLVED: To provide a tank for a fluid containing carbon and hydrogen, which is also suitable for the fluid of low purity. SOLUTION: The tank accepts the fluid that contains carbon and hydrogen for supplying a working medium to a fuel cell device. The tank comprises an inlet and an outlet for the fluid, and at least one filtration equipment arranged between the inlet and the outlet to clean the fluid.
Abstract:
PROBLEM TO BE SOLVED: To eliminate the adverse effects of peroxides generated at the cathode of a fuel cell. SOLUTION: The fuel cell 1 has two electrodes 2 and an ion-exchange membrane 6, with each of the electrodes 2 having an electrode catalyst layer 4 and at least one gas passage for a reaction gas 7. The fuel cell contains at least one kind of additive that works to prevent formation of peroxides and/or decompose peroxides. A method is disclosed for using at least one kind of additive inside or over the electrode 2 of the fuel cell 1 having the ion- exchange membrane 6, the electrode catalyst layer 4, and the electrode 2 having at least one gas flow passage for the reaction gas 7. The at least one kind of additive works to prevent formation of and/or decompose peroxides inside or over the electrode 2.
Abstract:
Chromium-free catalyst for the low-temperature conversion of carbon monoxide and water into hydrogen and carbon dioxide, which comprises a mixed oxide of at least copper oxide, zinc oxide and aluminium oxide, with the catalyst precursor being present essentially as hydrotalcite and the content of copper oxide being not more than 20% by weight.
Abstract:
A method of charging a vertical tube having an internal diameter of 50 mm or less with catalyst particles, which comprises introducing a filling aid into the vertical tube, where the filling aid comprises a flexible elongated body and the ratio of the cross section of the flexible elongated body to the cross section of the tube is from 0.003 to 0.08, and introducing the catalyst particles into the tube.
Abstract:
Removal of sulfur compounds from gases containing hydrocarbons is carried out using catalysts (I) (other than activated carbon or zeolites) containing one or more of copper, silver, zinc, molybdenum, iron, cobalt and/or nickel, at -50 to +150[deg]C and 0.1-10 bars. An independent claim is included for new catalysts (I'), comprising 1-99.8 wt. % copper, silver, zinc, molybdenum, iron, cobalt and/or nickel and 0.2-99 wt. % oxides of Group IIB, IIIB, IVB, VIB, VIII, IIIA or IVA elements, which are solid at least up to 250[deg]C.
Abstract:
Container (G) for receiving a carbon- and hydrogen-containing fluid (B) comprises an inlet (E) and an outlet (A) for the fluid with an admission device (D) for cleaning the fluid arranged between the inlet and the outlet. Preferred Features: The admission device has zones (1-5) having regions of different permeability for components of the fluid. At least one zone is an adsorber and one is a particle filter.
Abstract:
The invention relates to a method for producing hydrogenous gases by reactin g hydrocarbons with air and/or water at temperatures of from 300 to 1000 ~C an d a pressure of from 1 to 20 bar in the presence of a catalyst. The catalyst used is a spinell that contains at least one element of subgroup VIII of the periodic system.
