摘要： A catalyst bed comprising a ceramic or metallic foam comprising one or more NOx reduction catalysts is described. Further, a method for reducing the concentration of NOx in a dust containing gas stream comprising: a) passing a first gas stream containing NOx into a contacting zone; b) contacting the first gas stream with a ceramic or metallic foam catalyst bed having one or more flow paths through the catalyst bed wherein the ceramic or metallic foam comprises a NOx reduction catalyst to produce a second gas stream with a reduced NOx concentration; and c)passing the second gas stream out of the contacting zone wherein the first gas stream has a dust concentration of at least 5 mg/Nm3 and the second gas stream comprises at least 50% of the amount of dust in the first gas stream.

摘要： The invention relates to a method for preparing a hydrogenation catalyst or catalyst precursor comprising a catalytically active material and a carrier material. The method involves the mixing of an acidic solution comprising metal ions of a metal selected from the IUPAC group 8, 9 or 10 metals, preferably cobalt, a suspension comprising the carrier material and an alkaline solution. The invention also relates to a precursor of a hydrogenation catalyst wherein the precursor comprises crystallites of metal oxides having an average size of max. 8 nm.
