发明名称 Process for the treatment of catalyst for the purification of flue gas
摘要 <p>Catalyst carrier having at least a contact area of a porous material, at which a fluid is guided past, is claimed, where the catalyst carrier is obtained by cleaning a selective catalytic reduction catalyst carrier and removing the reaction products from the selective catalytic reduction catalyst carrier; introducing at least a substance from catalytically relevant substance e.g. tungsten oxide into the pores of the catalyst carrier using a transport fluid; subsequently introducing the transport fluid into the pore; and removing the block fluid and the transport fluid from the pores. Catalyst carrier having at least a contact area of a porous material, at which a fluid is guided past, is claimed, where the catalyst carrier is obtained by cleaning the selective catalytic reduction catalyst carrier and removing the reaction products from the selective catalytic reduction catalyst carrier; introducing at least a substance from catalytically relevant substance of tungsten oxide, vanadium pentoxide or molybdenum oxide into the pores of the catalyst carrier using a transport fluid, where: the substance in the transport fluid exists as ions and the catalytic relevant substance after removing the transport fluids remains on pore wall surface, and the introduction step takes place in such a way that, first a blocking fluid is introduced into the pores such that the pores in contact areas beyond a certain pore depth are filled with the blocking fluid; subsequently introducing the transport fluid into the pore by immersing the catalyst carrier into the transport fluid; and removing the block fluid and the transport fluid from the pores, where: the catalytically relevant substance remains at least partially on the pore wall surface such that at least a majority of the pores on pores wall surface depends on the surface-related amount of the catalytically relevant substance, and the surface-related amount of catalytically relevant material within the pore exceeding the specific pore depth drops is reduced.</p>
