Catalytic filter technology provides Important Flexibility for Controlling PM, NOx, SOx, O-HAPS - Case study
Catalyst-embedded ceramic filters offer a way to remove NOx at lower temperatures, while simultaneously removing PM, SOx, and HCI. The technology also removes organic hazardous air pollutants, THC, dioxins, and mercury. Applications include the Cement NESHAP; Boiler MACT; incinerator CISWI MACT; Hazardous Waste MACT; glass furnaces; ceramics manufacturing, including tracking proppants, kilns, ...

Design of a dual-bed catalyst system with microporous carbons and urea-supported mesoporous carbons for highly effective removal of NOx at room temperature
Abstract A dual-bed catalyst system is designed to remove NOx at room temperature, which consists of a microporous spherical activated carbon (SAC) layer and a urea-supported spherical mesoporous carbon (SMC) layer. The SAC layer, with plenty of narrow micropores acting as a nano-cage for NO adsorption, could improve the oxidation of NO into NO2, while the urea-supported SMC layer with large ...

Ceramic catalyst filters destroy air pollutants - Case study
Catalyst-embedded ceramic filters offer a new technological capability of removing NOx at lower temperatures, while simultaneously removing PM, SOx and HC1. The technology also removes organic hazardous air pollutants (O-HAPS) THC, dioxins and mercury, all in a single compact system. Applications for the technology include: the Cement NESHAP; Boiler MACT for coal; incinerator CISWI MACT; ...

New catalytic filter technology provides important added flexibility in controlling PM, NOX, SOX and O-HAPS - Case study
Catalyst-embedded ceramic filters offer a new technological capability of removing NOX at lower temperatures, while simul-taneously removing PM, SOX and HCl. The technology also removes organic hazardous air pollutants (O-HAPS) THC, dioxins and mercury, all in a single compact system. Applications for the technology include: the Cement NESHAP; Boiler MACT for coal; incinerator CISWI MACT; ...

The chemical aspect of NOx scrubbing, pollution engineering
With the passage of the 1990 Clean Air Act Amendments, many chemical and metal industries and utility producers will now be required to further limit the amount of NOx (Nitrogen Oxides) produced. NOx is a precursor to ozone in the atmosphere, and is believed to be a major contributor to acidic deposition (acid rain). Formation of ozone: NOx is produced in a variety of different processes, ...

Mercury Control Demonstrations
C1.1 | Halogens and Sulfur in Coals and their Influence on Co-benefit Mercury Capture Bernhard Vosteen | President, Vosteen Consulting Gmbh Not only the range of the coal mercury content itself, but also the range of the native halogen and sulfur contents in coal are of great influence on co-benefit mercury capture, wet and dry. The specific role of different halogens is discussed with ...
