A NEW TECHNIQUE IS PROPOSED FOR THE PREPARATION OF METAL-SUPPORTED METAL (MSM) CATALYSTS. THE KEY FEATURE OF THIS TECHNIQUE INVOLVES THE PREPARATION OF A THIN LAYER OF POROUS METAL ON TOP OF A METAL SUBSTRATE SUCH THAT THE POROUS METAL SURFACE IS AN INTEGRAL PART OF THE METAL SUPPORT. SUBSEQUENT INTEGRATION OF PT AND RH ON THE POROUS METAL SURFACE WILL PRODUCE THE MSM CATALYST. THIS CATALYST IS US ...

THE EMISSION OF HALOGEN CONTAINING POLLUTANTS FROM A VARIETY OF POWER GENERATING, WASTE PROCESSING, CHEMICAL PRODUCTION, AND SOLVENT USING INDUSTRIES IS AN ENVIRONMENTAL CONCERN OF MAJOR SIGNIFICANCE. INORGANIC HALOGEN SPECIES, INCLUDING HYDROGEN CHLORIDE AND HYDROGEN FLUORIDE, REPRESENT MAJOR POTENTIAL HEALTH THREATS TO BOTH HUMAN, ANIMAL, AND PLANT COMMUNITIES. ORGANIC HALOGENATED COMPOUNDS (HOC ...

The flue gases of combustion-type power plants contain small, respirable ash andfume particles which originate from the inorganic species in the fuel. Coalburning power plants, for example, have a notorious reputation for spewing outflue gas particles originating from the mineral mater in the coal. These fluegas particles (10 microns in diameter) must be characterized for two reasons:1) to deter ...

The problem addressed in this project is the need to monitor oxides of nitrogen(NOx, ie NO and NO2) levels in the combustion gases of stationary sources suchas power plants in order to facilitate on-line control of the scrubbers that willbe used to remove those pollutants. Since the measurements are in the parts permillion range, simpler and less expensive instruments than those currently used,su ...

Developments in on-site spent solvent recovery have implications for reducedenvironmental pollution in the dry cleaning, furniture and paint manufacturingindustries as well as in a range of commercial services. Effluents from solventrecovery operations include fugitive emissions, vent stack gases and water/solvent mixtures. At present, the scale of solvent-recovery operations incertain industrie ...

About 75,000,000 lbs of paint sludge is generated by the U.S. automotive industry each year. This type of waste and (similar streams from other industries) make significant contributions to landfills. The solution proposed by ASTER, Inc., proven feasible during the Phase I of this work, is to recycle the paint sludge into ingredients for automotive sealants. This new approach results in waste g ...

THE CONTROL OF VOLATILE ORGANIC CONTAMINANT (VOC) EMISSIONS FROM INDUSTRIAL PROCESSES AND FUEL SOURCES IS AN IMPORTANT ENVIRONMENTAL PROBLEM. STRINGENT REGULATIONS HAVE BEEN ENACTED THAT WILL LIMIT SUCH EMISSIONS, HEIGHTENING THE NEED FOR SMALL, SIMPLE UNITS THAT CAN RECOVER VOCS AND RETURN THEM AS REUSABLE COMPOUNDS. CURRENT VOC-REMOVAL TECHNOLOGIES, SUCH AS INCINERATION, CARBON ADSORPTION, AND C ...

The U.S. chemical industry accounts for over 200 million tons/year of hazardousliquid waste containing organic chemicals. These waste streams are difficult totreat using conventional technologies such as carbon adsorption and steamstripping. Membrane processes--particularly pervaporation--offer energy and costadvantages over conventional techniques. However, current pervaporationmembrane-module ...

Out of 50 million tons of fly ash generated each year in the United States, only27% is reused or recycled. The remaining 73% is landfilled which presentspotential environmental problems in the future. This projects main objective isto develop a new class of construction material from the Chemically Activated FlyAsh (CAFA) in conjunction with fine and coarse aggregates, and determinepertinent mec ...
