This book was released on 1994 with total page 214 pages. Available in PDF, EPUB and Kindle. Book excerpt: In a conventional well-mixed fluidized bed the solids are almost completely mixed and the residence time for individual particles may vary between zero and infinity. For materials especially sensitive to the processing time, a wide distribution of residence time is extremely undesirable. A multi-compartment fluidized bed was proposed to minimize this problem. The two-compartment fluidized bed system was designed and experimentally investigated with positive results. Residence time distributions were measured with glass bead particles of 379 p.m mean diameter size. Tracer particles were colored glass beads which had exactly the same properties as the particles used for bed material. Two theoretical models were proposed to predict the flow behavior of solids through the two-compartment fluidized bed vessel. The results show the solids flow pattern can be described by the axial dispersion plug flow model and the tanks-in-series model. The parameters of both models can be determined by minimizing the sum of the squared differences between experimental data and model predictions curves. The influence of fluidization velocity, diameter of the orifice connecting the two adjacent compartments, and the height of the overflow exit orifice were investigated. The two-compartment fluidized bed can improve the residence time distribution of solids from a single fluidized bed. The residence time distribution of solids was also improved with decreasing fluidizing gas velocity. Orifice diameter and height of the overflow exit orifice did not influence significantly on particles flow in the two-compartment fluidized bed system. However, a solids mass flow through the partition orifice is predicted reasonably well, within moderate range of variance, by equation developed by de Jong (1965) [12].

This book was released on 2012-12-06 with total page 341 pages. Available in PDF, EPUB and Kindle. Book excerpt: Masters Theses in the Pure and Applied Sciences was first conceived, published, and disseminated by the Center for Information and Numerical Data Analysis and Synthesis (CINDAS)* at Purdue University in 1957, starting its coverage of theses with the academic year 1955. Beginning with Volume 13, the printing and dis semination phases of the activity were transferred to University Microfilms/Xerox of Ann Arbor, Michigan, with the thought that such an arrangement would be more beneficial to the academic and general scientific and technical community. After five years of this jOint undertaking we had concluded that it was in the interest of all concerned if the printing and distribution of the volumes were handled by an international publishing house to assure improved service and broader dissemination. Hence, starting with Volume 18, Masters Theses in the Pure and Applied Sciences has been disseminated on a worldwide basis by Plenum Publishing Corporation of New York, and in the same year the coverage was broadened to include Canadian universities. All back issues can also be ordered from Plenum. We have reported in Volume 40 (thesis year 1995) a total of 10,746 thesis titles from 19 Canadian and 144 United States universities. We are sure that this broader base for these titles reported will greatly enhance the value of this impor tant annual reference work. While Volume 40 reports theses submitted in 1995, on occasion, certain uni versities do report theses submitted in previous years but not reported at the time.

Download or read book Diameter Transformed Fluidized Bed written by Youhao Xu and published by Springer Nature. This book was released on 2020-06-05 with total page 421 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book puts forward the concept of the Diameter-Transformed Fluidized Bed (DTFB): a fluidized bed characterized by the coexistence of multiple flow regimes and reaction zones, achieved by transforming the bed into several sections of different diameters. It reviews fundamental aspects, including computational fluid dynamics simulations and industrial practices in connection with DTFB. In particular, it highlights an example concerning the development of maximizing iso-paraffins (MIP) reactors for regulating complex, fluid catalytic cracking reactions in petroleum refineries. The book is a must-have for understanding how academic and industrial researchers are now collaborating in order to develop novel catalytic processes.
Download or read book Fluidized Bed Reactors Processes and Operating Conditions written by John G. Yates and published by Springer. This book was released on 2016-09-27 with total page 214 pages. Available in PDF, EPUB and Kindle. Book excerpt: The fluidized-bed reactor is the centerpiece of industrial fluidization processes. This book focuses on the design and operation of fluidized beds in many different industrial processes, emphasizing the rationale for choosing fluidized beds for each particular process. The book starts with a brief history of fluidization from its inception in the 1940’s. The authors present both the fluid dynamics of gas-solid fluidized beds and the extensive experimental studies of operating systems and they set them in the context of operating processes that use fluid-bed reactors. Chemical engineering students and postdocs as well as practicing engineers will find great interest in this book.
