Book Description
"Los procesos de oxidación químicos son una herramienta universal para el tratamiento de aguas subterráneas, efluentes industriales y aguas residuales. Una de estas técnicas se basa en la generación de radicales hidroxilos (·OH), y se le conoce con el nombre de proceso de oxidación avanzada (AOP). Aunque dicho proceso es considerado una poderosa herramienta para la degradación de contaminantes, este enfrenta varias limitación prácticas especialmente en función del sistema seleccionado para la generación de los ·OH. El objetivo de este trabajo fue proponer y poner a prueba una estrategia novedosa con el fin de ampliar la aplicabilidad de la oxidación avanzada, integrando al sistema el uso de reactores de membrana catalítica (CMR). Los esfuerzos fueron enfocados en la aplicación de los CMRs para la oxidación de un compuesto orgánico modelo (fenol), utilizando peróxido de hidrogeno generado in situ como fuente de ·OH. Las características de los CMRs permiten la síntesis directa de H2O2" -- TDX.

Book Description
Significant progress was made in 1991 on the development of ceramic membranes as catalytic reactors. Efforts were focused on the design, construction and startup of a reactor system capable of duplicating relevant commercial operating conditions. With this system, yield enhancement was demonstrated for the dehydrogenation of ethylbenzene to styrene in a membrane reactor compared to the standard packed bed configuration. This enhancement came with no loss in styrene selectivity. During operation, coke deposition on the membrane was observed, but this deposition was mitigated by the presence of steam in the reaction mixture and a steady state permeability was achieved for run times in excess of 200 hours. Work began on optimizing the membrane reactor by exploring several parameters including the effect of N2 diluent in the reaction feed and the effect of a N2 purge on the permeate side of the membrane. This report details the experimental progress made in 1991. Interactions with the University of Wisconsin on this project are also summarized. Finally, current status of the project and next steps are outlined.

Book Description
Integrated Membrane Reactors explores recent developments and future perspectives in the area of membrane reactor (MR) systems. It includes fundamental principles, the different types of membrane materials (such as polymeric and inorganic), the different types of membrane reactors (such as Micro MRs, Enzymatic MRS, Photo-catalytic MRs, Pervaporation MRs, Electrochemical MRs, etc.), their industrial perspective and, finally, there also is an economic evaluation of the metallic MRs. The book provides an extensive review in the area of MRs for each kind of application present in the specialized literature and discusses their modelling and design approaches necessary for MR systems validation in achieving high conversions, energy savings, high yields and high hydrogen (or others) products of the reactions studied. - Includes membrane preparation and characterization - Describes all the kinds of membrane reactors today under study - Focuses on many applications of membrane reactors in the area of chemical and biochemical engineering - Discusses simulation of membrane reactors enabling their design - Introduces the concepts of process intensification and process integration - Illustrates all the advantages of membrane reactors with respect to the so-called traditional/convention reactor

Book Description
Membrane Reactors for Hydrogen Production Processes deals with technological and economic aspects of hydrogen selective membranes application in hydrogen production chemical processes. Membrane Reactors for Hydrogen Production Processes starts with an overview of membrane integration in the chemical reaction environment, formulating the thermodynamics and kinetics of membrane reactors and assessing the performance of different process architectures. Then, the state of the art of hydrogen selective membranes, membrane manufacturing processes and the mathematical modeling of membrane reactors are discussed. A review of the most useful applications from an industrial point of view is given. These applications include: natural gas steam reforming, autothermal reforming, water gas shift reaction, decomposition of hydrogen sulphide, and alkanes dehydrogenation. The final part is dedicated to the description of a pilot plant where the novel configuration was implemented at a semi-industrial scale. Plant engineers, researchers and postgraduate students will find Membrane Reactors for Hydrogen Production Processes a comprehensive guide to the state of the art of membrane reactor technology.
