Abstract: The invention relates to a catalyst comprising a monolith composed of a catalytically inert material with low BET surface area and a catalyst layer which has been applied to the monolith and comprises, on an oxidic support material, at least one noble metal selected from the group consisting of the noble metals of group VIII of the Periodic Table of the Elements, optionally tin and/or rhenium, and optionally further metals, wherein the thickness of the catalyst layer is 5 to 500 micrometers.

Abstract: A process for producing propylene oxide comprising reacting propene with hydrogen peroxide in the presence of a catalyst to give a mixture (G1) comprising propylene oxide, unreacted propene, and oxygen; separating propylene oxide from mixture (G1) to give a mixture (GII) comprising propene and oxygen; and adding hydrogen to mixture (GII) and reducing the oxygen comprised in mixture (GII) at least partially by reaction with hydrogen in the presence of a catalyst comprising copper in elemental and/or oxidic form on a support, wherein copper is present on the support in an amount of 30 to 80 wt.-% based on the whole catalyst and calculated as CuO.

Abstract: A method for dehydrogenating primary or secondary alcohols having 1 to 12 carbon atoms to give the corresponding aldehydes or ketones in which the alcohol is brought into contact with a catalytically active composition comprising an active component of the formula PdaBibYcZd, where Y is selected from the group consisting of Co, Rh, Pt, Ag, Au, and Z is selected from the group consisting of Na, Cs, Mg, Ca, Ba, V, Cr, W, Fe, Ni, Cu, Sb where the indices a, b, c and d give the mass ratios of the respective elements to one another, where a=0.1-3, b=0.1-3, c=0-3, d=0-1.
