NO oxidation using O3 is studied, including the product composition under different conditions and selectivity in complex flue gas. The O3/NO molar ratio determines type of products. N2O5 generated when greater than 1, yield increases with improvement ratio. High temperature leads to decomposition NO3 decrease yield. When caused high-temperature region, increase residence time not beneficial generation N2O5. In addition, water vapor gas formation at low temperatures (60–90 °C), but SO2, CO,...
Selective catalytic reduction using CO as a reducing agent (CO-SCR) has exhibited its application potential in coal-fired, steel, and other industrial sectors. In comparison to NH
Abstract Efficient low‐temperature NO reduction by transition metal‐based catalysts remains a significant challenge. In this study, Co‐based catalyst, Co 0 +CoO x @CS, encapsulated carbon microspheres and synthesized via one‐step in situ hydrothermal method, exhibits excellent conversion, exceeding 99% at 150 °C. X‐ray Absorption Fine Structure analysis reveals electronic interactions between C Co, anchoring nanoclusters to the microspheres. The resulting microporous structure enhances...
Mn-Based catalysts with a Mn loading of 4 wt% were prepared using an impregnation method.
Developing high–performance Ir–based catalysts for selective catalytic reduction of NOx by CO(CO–SCR) under low temperatures remains challenging. This study presents an catalyst encapsulated in ZSM–5 (Ir@ZSM–5), with Ir species partially confined micropores (Irδ+) and aggregated on the surface (Ir0), achieving ~88% conversion at 230 °C presence 5% O2 100 ppm SO2. The Irδ+ exhibit enhanced stability oxidized states, while surface–aggregated Ir0 species, weaker oxygen coordination, remain a...
The impact of the coexistence SO2 and NO in flue gas on Hg0 removal over HNO3-modified activated carbon (HNO3-AC) was evaluated. In addition, effect adding HCl also investigated. strongly depends upon composition acidic gas. results indicated that physically adsorbed inhibited because competitive adsorption, while chemically slightly promoted by generating HgSO4. formation N-containing active species, such as NO2, facilitates presence to primarily produce Hg(NO3)2 or HgO. comparison study...
