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:
A structured catalyst charge contains the following catalytically-active sections: (a) a section containing silver, an alkali metal and a porous carrier; and (b) a section containing an alkali metal phosphate and a layered silicate.
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:
A method for the conversion of mono-, di- or poly-olefin(s) into compound(s) with at least one carbonyl group involves carrying out the reaction in presence of a rhodium-containing catalyst.

Abstract:
A catalyst comprises either palladium and bismuth and optionally rhodium, gold, antimony, vanadium, chromium, tungsten, manganese, iron, cobalt, nickel, sodium, cesium and/or barium, or palladium, rhodium and bismuth and optionally gold, antimony, vanadium, chromium, tungsten, manganese, iron, cobalt, nickel, platinum, copper, silver, sodium, cesium, magnesium, calcium and/or barium. Independent claims are also included for the following: (1) the production of the catalyst by precipitating an active components from a solution of their salts or depositing the solution onto a support and then drying and calcining the product; (2) dehydrogenating hydrocarbons by contacting them with a catalyst as above.
