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: The invention relates to a catalytically active composition for the selective methanation of carbon monoxide which comprises at least one element selected from the group consisting of ruthenium, rhodium, nickel and cobalt as active component and a support material based on carbon. The invention further provides for the use of this catalytically active composition for the selective methanation of carbon monoxide and in the production of hydrogen for fuel cell applications.

Abstract: A methanol reforming catalyst containing passivated copper and zinc oxide and/or alumina can be prepared by (1) precipitating or spray-drying a mixture of catalyst precursor components dissolved or suspended in a diluent in order to form a solid catalyst precursor in the form of powder or granules, (2) calcining and reducing the solid catalyst precursor obtained in stage (1), (3) passivating the reduced catalyst precursor obtained in stage (2) and (4) shaping the passivated catalyst precursor obtained in stage (3) to form the catalyst. A reduction in the volume shrinkage and an increase in the mechanical hardness during operation of the methanol reforming catalyst are achieved by the preparation process.

Abstract: A container for uptaking, or storing, or releasing, or uptaking and storing, or uptaking and releasing, or storing and releasing, or uptaking, storing and releasing at least one gas, comprising a metal-organic framework material comprising pores and at least one metal ion and at least one at least bidentate organic compound which is bound to said metal ion, as well as to a fuel cell comprising said container, and to a method of using said container or said fuel cell for supplying power to power plants, cars, trucks, busses, cell phones, and laptops.

Abstract: The present invention relates to a process for the catalytic preparation of melamine by decomposition of urea over particular solid catalysts using a main reactor and an after-reactor. A catalyst having a low Lewis acidity is used in the main reactor and a catalyst having an equal or preferably higher Lewis acidity is used in the after-reactor.

Abstract: An organometallic framework material is prepared by a process which comprises reacting a fluid mixture comprising a metal salt with at least one at least bidentate organic compound capable of coordination to metal ions in the presence of at least one base and a solvent, where the solvent comprises at least one cyclic amide (lactam) and/or at least one cyclic ester (lactone).

Abstract: The present invention relates to the technical field of storing gas including methane and hydrogen, in particular to the fuel cell technology. In particulars it relates to a method of using a metallo-organic framework material comprising pores and at least one metal ion and at least one at least bidentate organic compound.

Abstract: Catalysts containing passivated copper and zinc oxide and/or alumina are prepared by (1) precipitating a mixture of catalyst precursor components dissolved or suspended in a diluent with anion-containing precipitating agents, washing and drying to form a solid catalyst precursor in the form of powder or granules, (2) calcining the solid catalyst precursor obtained in stage (1) to an anion content from the precipitating agent of from 0.1 to 2.5% by weight and (3) shaping and, if required, reducing and passivating the calcined catalyst precursor from stage (2) in any desired order to form the catalyst.

Abstract: The present invention relates to a container for uptaking, or storing, or releasing, or uptaking and storing, or uptaking and releasing, or storing and releasing, or uptaking, storing and releasing at least one gas, comprising at least one opening for allowing the at least one gas to enter and exit or at least one opening for allowing the at least one gas to enter and at least one opening for allowing the at least one gas to exit said container, and a gas-tight mechanism capable of storing the at least one gas under a pressure of from greater than 45 to 750 bar inside the container, said container further comprising a metallo-organic framework material comprising pores and at least one metal ion and at least one at least bidentate organic compound which is bound to said metal ion, as well as to a fuel cell comprising said container, and to a method of using said container or said fuel cell for supplying power to power plants, cars, trucks, busses, cell phones, and laptops.

Abstract: The invention relates to a method for producing catalysts by immersion coating a metallic support with at least one platinum metal. An aqueous medium which comprises at least one platinum metal complex, at least one reduction agent and at least one complexer and which has a pH value of more than 4 is brought into contact with the metallic support in order to deposit the platinum metal, the platinum metal being deposited in the form of discreet, immobilised particles. The invention also relates to the catalysts obtained using this method and to their use for producing hydrogen peroxide and for hydrogenating organic compounds.

Abstract: A fuel tank for motor vehicles which is connected to a supplementary tank containing a flame-coloring additive, where a data recorder causes, in the event of a fault signal, the flame-coloring additive to be added to the fuel tank from the supplementary tank, and a process for adding a flame-coloring additive to the fuel in a fuel tank.
