 | An inexpensive material was recently developed that appears to effectively capture mercury from simulated coal-fired flue gases when injected into ductwork at modest rates. Importantly, the new sorbents appear to be effective at high temperatures, 300 deg F to 400 deg F. This means that inexpensive gas-cooling or fabric-filter retrofits are not required and that fly ash will remain saleable. Consequently, preliminary estimates of their cost ... |

| An inexpensive material was recently developed that appears to effectively capture mercury from simulated coal-fired flue gases when injected into ductwork at modest rates. Importantly, the new sorbents appear to be effective at high temperatures, 3000F to 4000F. This means that inexpensive gas- cooling or fabric-filter retrofits are not required and that fly ash will remain saleable. Consequently, preliminary estimates of their cost effectiveness suggest costs approximately one-tenth of those ... |

| The purpose of this document is to describe the development and demonstration of several new technologies for controlling air pollutants, particularly nitrogen oxides (NOx) and small particulates. NOx stands out as one of the most difficult air pollutants to control. The U.S. Air Force employs many different combustion sources that emit NOx at its facilities around the world. Increased attention is being given to NOx because of the role it ... |

| This report describes the development and demonstration of several new technologies for controlling air pollutants, particularly nitrogen oxides (NOX) and small particulates. It provides the results of a project undertaken to investigate potential NOx problems at military sites and to develop potential solutions. Work on the project was performed primarily at McClellan AFB in California and at Sorbent Technologies' facilities in Ohio. The research work involved gas-cleaning approaches and centered ... |

| The U.S. Air Force employs many combustion sources at its facilities, including boilers, diesel engines, turbines, incinerators, and motor vehicles, that produce exhaust gases containing undesirable components. Components of concern include nitrogen oxides (NOx), carbon monoxide (CO), PM-10 particulate matter, sulfur dioxide (SO,), and a long list of compounds considered toxic by nature. Recently, Sorbent Technologies Corporation (Sorbtech) developed a new filter technology for the Air Force to control emissions ... |

|
| Vermiculite, vermiculite coated with magnesia, and activated carbon sorbents have successfully removed NOx (and carbon monoxide and particles) from combustion exhausts in a subscale drone jet engine test cell (JETC), but back pressure so generated elevated the temperature of the JETC and of the engine. The objective of this effort was to explore the feasibility of locating the sorbents in the face of the duct or of baffles parallel to ... |
