Download or read book Effect of Aluminum and Iron on Odors, Digestion Efficiency, and Dewatering Properties written by John T. Novak and published by IWA Publishing. This book was released on 2010-03-10 with total page 60 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study was designed to be a follow up of the WERF III (Adams, et al., 2007) odor study. It was found in the WERF III study that iron and aluminum appeared to play important roles in odor generation so some additional data was sought to determine the role these play in determining odor. In this portion of the study, the impact of iron and aluminum in sludges on both digestion and odors was investigated. Three distinct locations for the iron and/or aluminum were studied. First, the impact of iron and aluminum in the raw sludges on digestion and odors was evaluated. Second, the impact of the addition of iron or aluminum for chemical phosphorus removal in the activated sludge process was studied. Third, the direct addition of iron to the feed to an anaerobic digester was evaluated. All studies were conducted in the lab using a variety of sludges collected from seven wastewater utilities. In addition to digestion and odors, data were collected for sludge dewatering properties as indicated by the polymer conditioning requirements and dewatered cake solids. Both the iron and aluminum content in raw sludges being fed to anaerobic digesters impact the digestability, dewatering and TVOSC generation. A reasonable correlation between the iron content in the raw sludge and volatile solids reduction by anaerobic digestion was found. More iron resulted in higher volatile solids reduction except for the two plants that either received chemical sludge in the influent that contained iron and/or aluminum (Plant E) or had iron added in the treatment process (Plant F). This finding is important in that it provides for the prediction of digester performance based on the influent iron content. Aluminum appeared to also influence digestion, reducing the digestability of sludges. However, in this study, it was difficult to separate both the effects of iron and aluminum. Iron also had a major impact on dewatering. There was a distinct relationship between the iron content of the raw sludge and polymer dose requirements. As the iron increased, the polymer dose increased following digestion. As suggested in the WERF III report, iron appeared to play a role in TVOSC production from dewatered sludge cakes. As the iron content increased, the TVOSC generation increased. As a result, iron increases both the volatile solids reduction and TVOSC generation. The implication of this is that sludges that digest better also generate higher TVOSC. This has important implications for the regulations governing vector attraction based on volatile solids reduction. These regulations need to be changed or dropped from the regulations. Some of the data in this study shows a result that is contradictory to conventions thought. That is: as the volatile solids destruction increases, the TVOSC generation will also increase.

Book excerpt: Since the turn of the last century when the field of catalysis was born, iron and cobalt have been key players in numerous catalysis processes. These metals, due to their ability to activate CO and CH, haev a major economic impact worldwide. Several industrial processes and synthetic routes use these metals: biomass-to-liquids (BTL), coal-to-liquids (CTL), natural gas-to-liquids (GTL), water-gas-shift, alcohol synthesis, alcohol steam reforming, polymerization processes, cross-coupling reactions, and photocatalyst activated reactions. A vast number of materials are produced from these processes, including oil, lubricants, waxes, diesel and jet fuels, hydrogen (e.g., fuel cell applications), gasoline, rubbers, plastics, alcohols, pharmaceuticals, agrochemicals, feed-stock chemicals, and other alternative materials. However, given the true complexities of the variables involved in these processes, many key mechanistic issues are still not fully defined or understood. This Special Issue of Catalysis will be a collaborative effort to combine current catalysis research on these metals from experimental and theoretical perspectives on both heterogeneous and homogeneous catalysts. We welcome contributions from the catalysis community on catalyst characterization, kinetics, reaction mechanism, reactor development, theoretical modeling, and surface science.

Available in PDF, EPUB and Kindle. Book excerpt: The Chemical Physics of Solid Surfaces, Volume 6: Coadsorption, Promoters, and Poisons focuses on the processes, reactions, and approaches involved in coadsorption and the functions of promoters and poisons in synthesis and reactions. The selection first offers information on adsorbate-adsorbate interactions on metal surfaces and interaction between alkali metal adsorbates and adsorbed molecules. Discussions focus on coadsorption of alkali metals and other molecules; model experiments of catalyst promotion; effective medium theory; direct and indirect hybridization effects; and elastic interaction between adsorbates. The publication then ponders on coadsorption of carbon monoxide and hydrogen on metal surfaces and adsorption on bimetallic surfaces. The manuscript examines the chemical properties of alloy single crystal surfaces and promotion in ammonia synthesis. Topics include substrate dependence of nitrogen adsorption and ammonia synthesis; effects of promotion on nitrogen dissociation and ammonia synthesis; and theoretical modeling. The text then elaborates on promotion in the Fischer-Tropsch hydrocarbon synthesis, promoters and poisons in the water-gas shift reaction, and strong metal-support interactions. The selection is a recommended reference for physicists and readers interested in coadsorption, promoters, and poisons.

Download or read book Catalytic Ammonia Synthesis written by J.R. Jennings and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 462 pages. Available in PDF, EPUB and Kindle. Book excerpt: The phenomenon of catalysis is found in many homogeneous and heterogeneous systems undergoing chemical change, where it effects the rates of approach to the equilibrium state in processes as diverse as those found in the stars, the earth's mantle, living organisms, and the various chemistries utilized by industry. The economies and the living standards of both developed and developing countries depend to varying degrees upon the efficacy of their chemical industries. Con sequently, this century has seen a wide exploration and expansion of catalytic chemistry together with an intensive investigation of specific, essential processes like those contributing to life-supporting agricultures. Prime among the latter must surely be the "fixation" of atmospheric nitrogen by catalytic hydrogenation to anhydrous ammonia, still the preferred synthetic precursor of the nitrogenous components of fertilizers. In each decade contemporary concepts and techniques have been used to further the understanding, as yet incomplete, of the catalyst, the adsorbates, the surface reactions, and the technology of large-scale operation. The contributors to the present volume review the state of the art, the science, and the technology; they reveal existing lacunae, and suggest ways forward. Around the turn of the century, Sabatier's school was extending the descriptive catalytic chemistry of hydrogenation by metals to include almost all types of multiple bond. The triple bond of dinitrogen, which continued to be more resistant than the somewhat similar bonds in carbon monoxide and ethyne, defied their efforts.

Available in PDF, EPUB and Kindle. Book excerpt: Catalyst lifetime represents one of the most crucial economic aspects in industrial catalytic processes, due to costly shutdowns, catalyst replacements, and proper disposal of spent materials. Not surprisingly, there is considerable motivation to understand and treat catalyst deactivation, poisoning, and regeneration, which causes this research topic to continue to grow. The complexity of catalyst poisoning obviously increases along with the increasing use of biomass/waste-derived/residual feedstocks and with requirements for cleaner and novel sustainable processes. This book collects 15 research papers providing insights into several scientific and technical aspects of catalyst poisoning and deactivation, proposing more tolerant catalyst formulations, and exploring possible regeneration strategies.
