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 ...

DIESEL ENGINES PLAY AN IMPORTANT ROLE IN THE UNITED STATES ECONOMY FOR POWER GENERATION AND TRANSPORTATION. HOWEVER, NOX AND SOOT EMISSIONS FROM BOTH STATIONARY AND MOBILE DIESEL ENGINES ARE A MAJOR CONTRIBUTOR TO AIR POLLUTION. MANY ENGINE MODIFICATIONS AND EXHAUST-AFTER-TREATMENT DEVICES HAVE BEEN PROPOSED AND TESTED TO REDUCE THE NOX AND SOOT EMISSIONS FORM DIESEL EXHAUSTS. SIMPLE TECHNIQUES FO ...

REMOVAL OF TOXIC METALS FROM WASTEWATER STREAMS HAS BECOME A PROBLEM OF INCREASING NATIONAL IMPORTANCE, AS A RESULT OF INCREASING CONCERN FOR OUR ENVIRONMENT, AND INCREASINGLY STRINGENT WASTE DISPOSAL REGULATIONS. CHROMATOCHEM, INC., HAS DEVELOPED AN ECONOMICAL AND EFFECTIVE NEW TECHNOLOGY FOR THE REMOVAL OF LOW LEVELS OF TOXIC METAL IONS FROM WASTEWATER STREAMS, USING SOLID PHASE EXTRACTION (SPE) ...

COALITION TECHNOLOGIES, LTD., (CTL) RESEARCH HAD IMPROVED A SIMPLE GAS PHASE TREATMENT (SULFONATION) OF WASTE RUBBER AND PLASTICS. RESULTS FROM LABORATORY SCALE EXPERIMENTS DONE AT MICHIGAN STATE UNIVERSITY HAVE SHOWN THAT CONCRETE MADE FROM SULFONATED RUBBER AND PLASTIC PROVIDED BY CTL HAS IMPROVED IMPACT RESISTANCE AS MEASURED BY ASTM STANDARD TESTS. IN MANY CASES, WASTE PLASTICS AND RUBBER ARE ...

MANY CONTAMINANTS OF CONCERN AT HAZARDOUS WASTE SITES ARE DIFFICULT TO TREAT BECAUSE OF THEIR CHEMICAL AND PHYSICAL CHARACTERISTICS. CONSTITUENTS WHICH HAVE LOW VAPOR PRESSURE, LOW WATER SOLUBILITY, AND LOW POTENTIAL FOR BIODEGRADABILITY ARE NOT CANDIDATES FOR MANY TECHNOLOGIES. METALS ARE A PRIME EXAMPLE AS ARE POLYCHLORINATED BIPHENYLS (PCBS). THE PROPOSED TECHNOLOGY IS A COLD MIX ASPHALT EMULSI ...

ENERGY AND ENVIRONMENTAL RESEARCH CORPORATION (EER) HAS DISCOVERED A RADICALLY NEW METHOD OF BURNING NATURAL GAS. WHILE THE BEST PRESENTLY AVAILABLE GAS COMBUSTION TECHNOLOGIES PRODUCE NOX AT THE 10 TO 20 PPM LEVEL, THIS NEW METHOD ALLOWS THE COMBUSTION OF NATURAL GAS TO BE DONE WITH A PRODUCTION OF NOX WELL BELOW 1 PPM. THIS NEW TECHNOLOGY IS PARTICULARLY WELL SUITED TO APPLICATION IN GAS FIRED D ...
