A method for the deposition of catalytically active components of high surface area support materials

摘要

the invention relates to a process for the removal of catalytic active components on the carrier hochoberflu00e4chige by dispersing in water and mixing the carrierdispersion with an aqueous solution of soluble precursors of the catalytically active components.the method is characterized by the fact that the ph of the dispersion to a value between 6 and 8 is set.before the aqueous solution of the precursors, stirring the dispersion through kapillarinjektion fed and that may then the early stages of catalytic active componentskapillarinjektion a diluted base on the material to be precipitated.
