Available in PDF, EPUB and Kindle. Book excerpt: This report provides the results of a study conducted to determine the effectiveness of catalytic oxidation for destroying vapor phase chlorinated hydrocarbons. The study was conducted on two pilot scale catalytic incinerator systems leased from vendors. One system employed a metal oxide catalyst in a fluidized bed configuration. The other system used a fixed bed proprietary catalyst, supplemented with UV light and ozone injection. Both systems were tested under a variety of temperatures and space velocities. The test vapor streams consisted of low concentrations (3 to 200 ppmv) mixtures of organic compounds, and included three streams which represented the emissions from air strippers used to treat contaminated groundwater at U.S. Air Force bases. The study results showed that the fluidized bed catalytic incinerator system was capable of achieving total organic destruction efficiencies of greater than 98%. The UV/ozone catalytic system failed to achieve high destruction efficiencies; with ozone injection, total destruction was 75%; without ozone, the maximum destruction efficiency was 64%.

This book was released on 2000 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: In situ hydrous pyrolysis/oxidation process is useful for in situ degradation of hydrocarbon water and soil contaminants. Fuel hydrocarbons, chlorinated hydrocarbons, polycyclic aromatic hydrocarbons, petroleum distillates and other organic contaminants present in the soil and water are degraded by the process involving hydrous pyrolysis/oxidation into non-toxic products of the degradation. The process uses heat which is distributed through soils and water, optionally combined with oxygen and/or hydrocarbon degradation catalysts, and is particularly useful for remediation of solvent, fuel or other industrially contaminated sites.

This book was released on 2014-07-24 with total page 1035 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book offers a comprehensive overview of the most recent developments in both total oxidation and combustion and also in selective oxidation. For each topic, fundamental aspects are paralleled with industrial applications. The book covers oxidation catalysis, one of the major areas of industrial chemistry, outlining recent achievements, current challenges and future opportunities. One distinguishing feature of the book is the selection of arguments which are emblematic of current trends in the chemical industry, such as miniaturization, use of alternative, greener oxidants, and innovative systems for pollutant abatement. Topics outlined are described in terms of both catalyst and reaction chemistry, and also reactor and process technology.

Download or read book Catalytic Dehalogenatin of Perchloroethylene in a Redox Environment written by and published by . This book was released on 2005 with total page 278 pages. Available in PDF, EPUB and Kindle. Book excerpt: The catalytic dehalogenation of tetrachloroethylene (PCE) occurs via oxidation or reductive hydrodechlorination. Catalytic oxidation uses oxygen to dehalogenate PCE into CO2 and Cl2. This process requires higher temperatures>350ʻC then reductive hydrodechlorination and can produce undesirable toxic products, such as dioxins and furans. Hydrodechlorination uses a reductant to reduce PCE to ethane, and intermediate products such as less chlorinated hydrocarbons. Catalyst deactivation and associated loss of activity are commonly observed. Here, we examined a redox environment for the destruction of PCE on commercially available and laboratory made precious metal loaded catalysts. When a mixture of PCE, oxygen and hydrogen are passed over the catalyst, the PCE is converted to ethane, CO2, water, and HCl as a function of temperature (ambient to 450ʻC) and hydrogen to oxygen ratio in the feed (0 to 5). In the laboratory experiments, high conversion of PCE was observed for relatively high H2/O2 ratios (84% conversion with H2/O2 = 2.15, 63% with H2/O2 = 1.18 at 350ʻC, for commercial catalyst) for retention time of ̃1 s. The conversion of PCE generally increased with increasing temperature for all H2/O2 ratios. In the strictly oxidation environment (H2/O2 = 0), PCE conversion was lower than with hydrogen at any given temperature (30% at 464ʻC). At lower temperature (350ʻC) the dominant carbon-containing product was ethane, under redox conditions. At high temperature (380ʻC) CO2 eluted from the reactor, suggesting that oxidation of reduction products or PCE occurs. Experiments were conducted by using a laboratory made catalyst. A mixture of three types of precious metals (Pt, Pd, and Rh) was impregnated onto a monolithic alumina support. These studies show no apparent performance difference between the two catalysts at high temperatures (280ʻC). However, at low temperatures the laboratory catalyst outperforms the commercial catalyst. It was speculated that this difference due to high metal loading of the laboratory catalyst (38.61 mg versus 1.27 mg).A field scale study of the commercial catalyst was undertaken at the Superfund Park-Euclid site in Tucson, Arizona, where the soil is contaminated with PCE and other volatile hydrocarbons. Gases from a soil-vapor extraction unit were fed to the reactor, Even though the soil vapor contained high oxygen (>17%), high PCE conversion with and without hydrogen was observed. Due to the relatively high cost associated with the use of hydrogen, propane, methane, and diesel were investigated as replacement reductants. The results indicate that propane and diesel are promising replacements for hydrogen that deserve further investigation.
