Abstract:
The invention relates to a method for the aromatisation of non-aromatic hydrocarbons with 6 or more carbon atoms in the presence of water vapour and a catalyst that contains a support comprising zirconium oxide, in addition to tin and platinum in a ratio of at least 1. The invention also relates to the aforementioned catalyst.
Abstract:
The invention relates to a catalytically active composition containing Pd and Bi as active constituents, and at least one element selected from the group (a) consisting of Rh, Au, Sb, V, Cr, W, Mn, Fe, Co, Ni, Na, Cs and Ba; or Pd, Rh and Bi, and optionally an element selected from the group (a') consisting of Au, Sb, V, Cr, W, Mn, Fe, Co, Ni, Pt, Cu, Ag, Na, Cs, Mg, Ca and Ba. The invention also relates to a method for dehydrating hydrocarbons, preferably oxofunctionalised hydrocarbons such as cyclopentanone, cyclohexanone and isovaleraldehyde, by means of the catalytically active composition.
Abstract:
The present invention relates to a silver-containing catalyst system, which can be applied for the reaction of substrates with at least one C-C-double bond with at least one oxygen-containing or oxygen-supplying component with formation of at least one epoxide. The silver-containing catalyst according to the invention is characterized in that its activity as well as its selectivity is significantly increased with respect to the target product compared with the silver-containing catalysts of the state of the art, as a consequence of the process for the manufacture according to the invention, in which the synthesis of a silver-amine complex is carried out in absence of light and at temperatures below room temperature.
Abstract:
The subject invention relates to a device (10), in particular for performing catalytic screening with a reactor element (16), containing at least one gas inlet port (18) and a plurality of channels (42, 44) as well as a plurality of reaction chambers (46) that are connected to the channels (42, 44), characterized in that the channels (42, 44) form an angle not equal to zero degrees with the, at least one, gas inlet port (18).
Abstract:
The present invention relates to a method as well as a device for analysis of a fluid medium wherein the fluid medium is guided over at least one micro sensor (14) of a sensor assembly, comprising at least two microsensors (14) being identical or different, and wherein the at least one microsensor (14) is thermographically supervised with at least one detector with regard to an amendment of properties wherein the amendment of properties of the at least one microsensor (14) is specific for at least one predetermined component of the fluid medium.

Abstract:
In order to record a feed energy amount of a photovoltaic system that was potentially possible in a time period but not in fact fed, the system comprising one or more inverters for feeding electrical energy from one or more photovoltaic generators into an alternating current network (4), the photovoltaic system (1) is operated in the time period coupled to the alternating current network, wherein the inverter is, or the inverters are, operated differently in the time period, and wherein in the time period no energy is fed or a feed energy amount that is reduced with respect to the feed energy amount that was potentially possible is fed, and on the basis of the operating data of the inverter or inverters recorded during said differing operations the feed energy amount that was potentially possible in the time period is determined.
