Iron supported catalyst comprising a ca-deficient hydroxyapatite for waste gas treatment |
| abstract |
The invention relates to a catalyst composition for the catalytic reduction of NOx compounds, comprising Fe deposited on a porous support comprising at least 60% by weight of a calcium-deficient hydroxyapatite having a Ca / P molar ratio of less than 1, 67. The support preferably has a BET surface area of at least 110 m 2 / g and a pore volume of at least 0.5 cm 3 / g, both measured after heat treatment at 200 ° C. the catalyst composition can be contacted in a fixed or fluidized bed or by injection with a waste gas stream containing NOx at a temperature of at least 100 ° C and preferably at most 600 ° C to achieve, in the presence of O2, an NH3 reduction of at least a portion of the NOx. The process may further include injecting an alkaline sorbent into the waste gas stream to remove other contaminants such as heavy metals and / or acid gases with the alkaline sorbent. A mixture comprising the alkaline sorbent and the deNOx catalyst may be formed to treat the waste gas stream. The ammonia can be injected into the waste gas or can be included in the alkaline sorbent and / or the deNOx catalyst. |
