Download or read book Hydrotreatment and Hydrocracking of Oil Fractions written by B. Delmon and published by Elsevier. This book was released on 1997-01-20 with total page 581 pages. Available in PDF, EPUB and Kindle. Book excerpt: The symposium on Hydrotreatment and Hydrocracking of Oil Fractions aims to provide a global perspective and an inspection of the state-of-the-art of these processes. New American, European and Japanese environmental regulations call for advanced hydrotreatment processes for HDS and HDN for the removal of S- and Ni-components from oil fractions. These will alter the product slate of the oil refineries and the hydrocarbon composition of these products. Hydrocracking will play an important part in this shift. Adapting the operating conditions will not suffice to reach the desired product specifications and yields. Adequate catalysts will have to be developed. Powerful tools are now available for this, e.g. surface science techniques, molecular modeling and new types of reactors operated in a nonsteady mode. Another instrument in the improvement of hydrotreatment and hydrocracking units is the availability of more realistic kinetic models. These are based on a judicious insight into the reaction mechanism, also provided by the above-mentioned tools. Progress in the analytical techniques has allowed the reduction of the lumping of components in these kinetic models and first order kinetic equations are gradually replaced by equations accounting for the adsorption of the various components. More detailed and more realistic reactor models are now based on rigorous hydrodynamic models and their application has become possible through the rapidly increasing possibilities of computers.

Download or read book Geochemistry of Epigenesis written by A. I. Perel man and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 268 pages. Available in PDF, EPUB and Kindle. Book excerpt: In its classical sense "epigenesis" refers to all geological processes originating at or near the surface of the earth. It thus embraces all those phenomena which we associate with the land scape; Perel'man has already written extensively on this subject. The landscape, in the physical sense, is controlled by the interac tion of exogenic and endogenic agencies-on the one hand, the atmo sphere, the wind, the rain, and other components of the weather, the forces of running water and the planetary controls of gravitational and tidal nature; and on the other hand the materials of the earth's crust, from sediments to metamorphic rocks and igneous materials from deep endogenic sources. In practical terms the epigene region involves the products of weathering, the soils, the transported material, the colluvium of hillsides, and the alluvium of stream valleys. It involves those landforms that are products of the erosional sculpturing of the landscape, as well as those that result from accumulation, such as glacial moraines and desert sand dunes. The science of geomor phology is gradually beginning to evolve from a passive cataloging of scenery and its deduced causes (in the Davisian sense) into a vigorous study of dynamic processes. These are partly geophysical, in the sense of hydraulics and mechanical studies, and partly geo chemical.

Download or read book Simultaneous Sulfate Reduction and Metal Precipitation in an Inverse Fluidized Bed Reactor written by Denys Kristalia Villa Gómez and published by CRC Press. This book was released on 2022-01-27 with total page 206 pages. Available in PDF, EPUB and Kindle. Book excerpt: Industrial activities like textile processing and mining are typical sources of heavy metal-rich wastewaters. The sulfate reducing process has become an attractive method for the production of sulfide to precipitate metals since most of these streams also contain sulfate, which is the electron acceptor and, in less common cases, chemical oxygen demand which is the electron donor of sulfate reducing bacteria. The inverse fluidized bed (IFB) reactor is a system for the production of biogenic sulfide and metal precipitation in the same unit due to its configuration: the biomass floats on top of the reactor, whereas metal sulfide precipitates settle and thus can be recovered at the bottom. The main objective of this thesis was to elucidate the factors affecting simultaneous sulfate reduction and precipitation of heavy metals in an IFB reactor in order to optimize the metal recovery from wastewaters such as acid mine drainage. Therefore, this thesis focused on varying different operational conditions to study their effect on the solid-liquid separation and purity of the metal sulfide precipitates as well as on their effect on the sulfate reducing process. Furthermore, one chapter was focused on the study of strategies for sulfide control in the IFB reactor. In addition, recommendations for further research to improve the recovery of the metal sulfides in bioreactors are given.

This book was released on 2022-02-01 with total page 646 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nano-biosorbents for Decontamination of Water, Air, and Soil Pollution explores the properties of nanobiosorbents and their applications in the removal of contaminants from the natural environment. The use of nanobiosorbents for environmental protection is a combinational approach that incorporates nanotechnology with naturally occurring biopolymers that form an amalgamation of nano-biopolymers used as sorbent materials in the removal of a variety of contaminants from wastewaters. This is an important reference source for materials scientists, bioscientists and environmental scientists who are looking to understand how nanobiosorbents are being used for a range of environmental applications. Highlights the environmental applications of chitosan-based, cellulose-based and polymer-based nanoscale biosorbents Explains the advantages of using different types of nanobiosorbents for soil, water and air purification applications Assesses the challenges associated with manufacturing nanobiosorbents cheaply and on an industrial scale
