Copper supported catalyst comprising a Ca-deficient hydroxyapatite for waste gas NOx removal |
| abstract |
A porous material comprises at least 60 wt % of a calcium-deficient hydroxyapatite having a Ca/P molar ratio of less than 1.67, having a specific BET surface area of at least 110 m2/g and a pore volume of at least 0.41 cm3/g, both measured after heat treatment at 120° C. A catalyst composition for catalytic reduction of NOx compounds, comprising an active catalyst component: Cu and/or CuO deposited on the porous material as support. A deNOx process according to which an ammonia source is injected into a combustion waste gas stream containing NOx; and to which the catalyst composition is brought into contact with the waste gas stream at a temperature of at least 100° C. and preferably at most 600° C. to carry out, in the presence of O2, a reduction by NH3 of at least a portion of the NOx. |
