Montmorillonites modified with polymer and promoted with copper as DeNOx catalysts
چکیده انگلیسی

Clays modified with polymer and promoted with copper cations were studied in selective catalytic reduction of NO with ammonia. The modification with polymer and promotion with copper did not influence the layered structure of pillared clays. Specific surface areas of the catalysts were between 22 and 98 m2/g, lower or much lower than for pillared supports. The following elements of the preparation influenced positively NO conversion: acidic pretreatment (or the choice of acidic clay), modification with polymer and copper promotion. The most active catalyst was based on acidic clay modified with polymer and promoted with copper. Selectivity to N2 did not deteriorate after polymer modification.
