A NOVEL PROCESS FOR FIXED-BED ADSORPTION USING ACTIVATED CARBON AND SOLVENT REGENERATION IS PROPOSED FOR INVESTIGATION. THE PROCESS OFFERS EASIER AND LESS COSTLY SOLVENT REGNERATION, REDUCED ADSORBER BED-LENGTH REQUIREMENTS, REDUCED CONCENTRATIONS OF ADSORBED WATER, AND LOWER PROCESS ENERGY REQUIREMENT AND CAPITAL AND OPERATING COSTS. THE PROCESS WILL HAVE APPLICATION TO THE RECOVERY OF SPECIFIC I ...

Fieldable, simple, cost-saving detection technologies for biological and chemical hazards are in great demand by security, emergency response and military forces. Experienced in developing toxin detection and environmental pollutant monitoring technologies, ADA Technologies, Inc. proposed to develop novel test kits for the rapid collection and identification of biological and chemical hazards on ...

The EPA has stated a need for technologies and instruments to monitor and warn of the presence of toxic contaminants in drinking water. An innovative device that could detect, identify and localize hazardous chemical contaminants in drinking water would be immensely valuable to water utility operators, emergency response personnel, and other decision-making officials charged with protecting the n ...

Clean and renewable liquid fuels from biomass offer reduced new emission of CO2 and less dependence on expensive and unreliable foreign oil. Currently, bioethanol serves in the U.S.A. as bled for gasoline but eventually it could replace gasoline in passenger cars altogether. Ethanol, however, contains only 2/3 of the energy of gasoline on equal volume basis, and if used at high concentration, it ...

Coal contains substantial sulfur that if not captured when burned, can significantly impact human health, SO2 and SOx emissions are highly regulated. This Small Business Innovation Research proposal presents a novel, proprietary approach for removing sulfur from gasified coal products at gasification temperatures. The approach is based upon the use of sulfide ion conducting metal sulfides. At h ...

The U.S. Environmental Protection Agency (EPA) has identified the need for an accurate and field-rugged instrument to monitor Chlorine Dioxide (ClO2) for use in monitoring building decontamination operations. The proposed Phase I study will evaluate the feasibility of designing and fabricating an advanced electrochemical ClO2 sensor, utilizing integrated solid polymer electrolyte proton-conduct ...

Because of the relatively high cost of biomass feedstocks compared to fossil fuels, biomass conversion processes must be highly efficient in order to provide a new-term contribution to the U.S. energy balance. Biodiesel is recognized as an important potential fuel, which is obtained by relatively simple esterification of fats or seed oils (soybean, rapeseed, etc.). In the manufacture of biodiese ...
