Abstract

The invention relates to an adsorbent composition containing an I B-group metal component, containing the following components: 50-99 wt% of heat-resistant inorganic oxide substrates by using the component as a reference, 0.5-35 wt% of at least one metal component selected from an I B group and 0.5-35 wt% of at least one metal component selected from an I A and / or II A group by oxide metering, wherein characterizing by an X-ray photoelectron spectroscopy, the metal component selected from the I B group exists in at least two different valence states of MIBi1 and MIBi2, wherein i1 is less than i2. Compared with the prior art, the composition provided in the invention has high regenerating stability when keeping high performance of removing sulfur oxides and nitric oxides from flue gas.

Description

technical field [0001] The invention relates to an adsorbent and its application, in particular to an adsorbent composition containing Group IB metal components and its application. Background technique [0002] Atmospheric sulfur oxide SOx (more than 95% is SO 2 ), nitrogen oxides NOx (more than 90% are NO) pollution problems are becoming more and more serious, and the flue gas produced by fuel combustion, metal smelting, etc. is the main source of SOx and NOx. These harmful gases cause serious damage to the ecological environment and human health. [0003] At present, the SOx emission control technology in the world is relatively mature. Although a series of researches have been carried out at home and abroad on the NOx emission control, the results are still not satisfactory. [0004] US6521559 discloses a columnar clay catalyst suitable for utilizing NH 3 Selective Catalytic Reduction (SCR) for reducing NO. The characteristics of this catalyst are mainly the introduc...
