Download or read book Catalysts and Processes for H2S Conversion to Sulfur written by Daniela Barba and published by Mdpi AG. This book was released on 2022-02-07 with total page 206 pages. Available in PDF, EPUB and Kindle. Book excerpt: Today, more stringent regulations on SOx emissions and growing environmental concerns have led to considerable attention on sulfur recovery from hydrogen sulfide (H2S). Hydrogen sulfide is commonly found in raw natural gas and biogas, even if a great amount is obtained through sweetening of sour natural gas and hydrodesulphurization of light hydrocarbons. It is highly toxic, extremely corrosive and flammable, and for these reasons, its elimination is necessary prior to emission in atmosphere. There are different technologies for the removal of H2S, the drawbacks of which are the high costs and limited H2S conversion efficiency. The main focus of this Special Issue will be on catalytic oxidation processes, but the issue is devoted to the development of catalysts able to maximize H2S conversion to sulfur minimizing SO2 formation, pursuing the goal of "zero SO2 emission". This Special Issue is particularly devoted to the preparation of novel powdered/structured supported catalysts and their physical-chemical characterization, the study of the aspects concerning stability and reusability, as well as the phenomena that could underlie the deactivation of the catalyst. This Special Issue comprises seven articles, one communication, and one review regarding the desulfurization of sour gases and fuel oil, as well as the synthesis of novel adsorbents and catalysts for H2S abatement. In the following, a brief description of the papers included in this issue is provided to serve as an outline to encourage further reading.

This book was released on 2001 with total page 9 pages. Available in PDF, EPUB and Kindle. Book excerpt: The development of low cost, highly efficient, desulfurization technology with integrated sulfur recovery remains a principle barrier issue for Vision 21 integrated gasification combined cycle (IGCC) power generation plants. In this plan, the U.S. Department of Energy will construct ultra-clean, modular, co-production IGCC power plants each with chemical products tailored to meet the demands of specific regional markets. The catalysts employed in these co-production modules, for example water-gas-shift and Fischer-Tropsch catalysts, are readily poisoned by hydrogen sulfide (H2S), a sulfur contaminant, present in the coal-derived fuel gases. To prevent poisoning of these catalysts, the removal of H2S down to the parts-per-billion level is necessary. Historically, research into the purification of coal-derived fuel gases has focused on dry technologies that offer the prospect of higher combined cycle efficiencies as well as improved thermal integration with co-production modules. Primarily, these concepts rely on a highly selective process separation step to remove low concentrations of H2S present in the fuel gases and produce a concentrated stream of sulfur bearing effluent. This effluent must then undergo further processing to be converted to its final form, usually elemental sulfur. Ultimately, desulfurization of coal-derived fuel gases may cost as much as 15% of the total fixed capital investment (Chen et al., 1992). It is, therefore, desirable to develop new technology that can accomplish H2S separation and direct conversion to elemental sulfur more efficiently and with a lower initial fixed capital investment.

Available in PDF, EPUB and Kindle. Book excerpt: Catalytic steam reforming has grown during the last two or three decades into one of the world's great catalytic processes. It is of major economic significance since the products from it form the feed for a number of other major processes. Nevertheless, catalytic steam reforming is a relatively difficult technology. It operates at high temperatures where problems of the maintenance of materials integrity and of catalyst stability and activity are severe, the establishment of high thermal efficiency of the plant is economically vital, and reactor operation is strongly influenced by mass and heat transport effects. The process is the subject of a thorough review by Dr. J. R. Rostrup-Nielsen who discusses both the basic cataly tic chemistry and the way in which this is interrelated with reactor and plant design. The use of catalytic converters for the purification of automotive exhaust gases is a relatively new technology which was brought into existence by social pressures for the preservation of acceptable environmental conditions. The majority of catalytic practitioners have been able to watch the growth of this technology from its inception to its current state of sophistication. Automotive catalytic converter technology is now in a mature state, and the chapter in this volume by Dr. K. C. Taylor provides a review which covers both the process chemistry and the most important converter design factors.

Download or read book Environmental Engineering IV written by Artur Pawlowski and published by CRC Press. This book was released on 2013-05-21 with total page 580 pages. Available in PDF, EPUB and Kindle. Book excerpt: Environmental engineering has a leading role in the elimination of ecological threats, and deals, in brief, with securing technically the conditions which create a safe environment for mankind to live in. Due to its interdisciplinary character it can deal with a wide range of technical and technological problems. Since environmental engineering uses the knowledge of the basic sciences – biology, chemistry, biochemistry and physics – it is able to neutralise pollution in all the elements of the environment, i.e. the hydrosphere, atmosphere and lithosphere. Moreover, environmental engineering deals with the design and maintenance of systems of water supply, sewage disposal, heating, ventilation and air-conditioning in buildings. Environmental Engineering IV contains 77 peer reviewed papers selected from 527 presented at the 4th Congress of Environmental Engineering (Lublin, Poland, 2-5 September 2012). The contributions are divided into 7 chapters: • Water supply • Water and wastewater treatment • Neutralization of solid wastes and sludge • Air protection and quality • Indoor microclimate • Energy • Biology and technology Environmental Engineering IV assesses the state of scientific research in various areas of environmental engineering, evaluates the organizational, technical and technological progress made in contributing to ecological security, and determines the place of environmental engineering in sustainable development, taking into account current political and economic conditions, and is a valuable source of information for the environmental engineering professional and academic community.
