Abstract:
A catalytically active filter for use in hot gas filtration to simultaneously remove solid particles and one or more undesirable compounds from a hot gas stream is partly or fully impregnated with a suitable catalyst. The compounds are selected from HCN, arsenic, organic sulfur compounds and carbonyls. The filter is prepared by making an impregnation liquid, which comprises a catalytically effective amount of at least one active metal and an oxide support, impregnating the filter substrate with the impregnation liquid by dipping it in the liquid or spraying it with the liquid to control the amount of liquid and drying and optionally calcining the impregnated filter.

Claim (Index 3):
A process for preparing a catalytically active filter for use in hot gas filtration according to  claim 1 , said method comprising the steps of\n providing an appropriately shaped filter substrate having a gas inlet surface and a gas outlet surface, preparing an impregnation liquid, which comprises an effective amount of one or more catalyst metal precursors which, inherently or upon activation, are capable of catalytically removing one or more compounds selected from hydrogen cyanide (HCN), arsenic, organic sulfur compounds and carbonyls, impregnating the filter substrate with the impregnation liquid such that a defined part of the filter substrate is filled with catalyst, and drying and optionally calcining the impregnated filter substrate.
