摘要： A method for reduction of NOx in a lean gaseous stream includes passing the gaseous stream at a temperature within the NOx sorbing temperature range through a catalyzed trap member having an oxidation catalyst intimately combined with a sorbent material. The sorbed NOx is periodically removed by introducing a combustible component into the gaseous stream and oxidizing it on the trap member to thermally desorb the NOx. The amount of combustible component introduced is limited to maintain the gaseous stream bulk composition lean and to avoid increasing the bulk temperature of the gaseous stream to a temperature which is too high for effective lean NOx abatement treatment. A suitable NOx abatement catalyst is used to reduce the desorbed NOx. Sorbing (trapping) and desorbing periods are alternated, usually in response to the temperature of the gaseous stream, and an apparatus to carry out the process is provided.

摘要： A NO.sub.x abatement composition comprises a NO.sub.x abatement catalyst and a NO.sub.x sorbent material which are dispersed in proximity to, but segregated from, each other on a common refractory carrier member (10). The NO.sub.x sorbent material comprises a basic oxygenated metal compound and optionally further comprises ceria. The NO.sub.x abatement catalyst contains a catalytic metal component including a platinum metal catalytic component. The catalytic metal component is segregated from the NO.sub.x sorbent material, which may be one or more of metal oxides, metal carbonates, metal hydroxides and mixed metal oxides. At least the catalytic metal component and the NO.sub.x sorbent material must be on, or comprise separate, particles; the particles may either be admixed or may be disposed in separate layers (20a, 20b) on the carrier member (10). A NO.sub.x abatement method employs the composition and includes periodically adjusting the gas being treated between lean and stoichiometric/rich operating cycles.
