摘要:
A catalyzed fabric filter substrate and a method of preparing the substrate comprising the steps of a) providing a fabric filter substrate b) providing an aqueous impregnation liquid comprising an aqueous hydrosol of one or more catalyst metal precursor compounds dispersed on nanoparticles of an oxidic metal carrier, a surfactant and a dispersing agent selected from the group of primary amines; c) impregnating the fabric filter substrate with the impregnation liquid; and d) drying and thermal activating the impregnated fabric filter substrate at a temperature below 300° C. to convert the one or more metal compounds of the catalyst precursor to their catalytically active form.
摘要:
Ceramic candle filter and use of the filter in the removal of particulate matter in form of soot, ash, metals and metal compounds, together with hydrocarbons and optionally nitrogen oxides being present in process off-gas or engine exhaust gas, wherein a noble metal comprising catalyst is arranged on the permeation side of the filter and/or on the dispersion side of the filter and/or within wall of the filter, said noble metal comprising catalyst contains a noble metal in an amount of between 20 and 1000 ppm/weight of the filter.
摘要:
The present invention relates to a catalyst comprising a ceramic support with a BET surface area of less than 40 m2/g and (a) 1.0 to 100 g of at least one metal of groups 8 to 12 of the periodic table of the elements, (b) 1.0 g to 100 g of at least one metal of groups 4 to 6 and 12 of the periodic table of the elements and (c) 1.0 g to 100 g of at least one metal of groups 14 and 15 of the periodic table of the elements per liter of bulk volume of the ceramic support, wherein the catalyst is additionally doped with (d) potassium in a content of from 0.0050% by weight to 0.20% by weight, based on the total weight of the catalyst. The present invention also provides the use of such a catalyst in the catalytic gas phase hydrogenation of nitroaromatics.

摘要:
Provided is a process for producing, in a single step, hydrocarbon fractions useful as diesel fuel or as a component of diesel fuel, from a mixture of a biological origin containing esters of fatty acids and, optionally, aliquots of free fatty acids. The process comprises the contemporaneous hydrodeoxygenation and hydroisomerization of the mixture of a biological origin, with the formation of linear and branched paraffins. The process is carried out in the presence of a catalytic composition comprising an amorphous carrier of an acidic nature and a metallic component containing one or more metals of group VIII.
