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.

Available in PDF, EPUB and Kindle. Book excerpt: A theoretical model describing the various kinetic reactions occurring in a biological fluidized bed reactor is proposed in this study. The model covers both the steady and the unsteady conditions of the process, taking into account the bulk liquid biomass activity, and adopting Rittmann's (1982) shearing model. The model resulted from writing four mass balance equations dealing with the state of the process. The state was defined by: (a) the substrate in bulk liquid medium, (b) the substrate in the biofihn, (c) the suspended microorganisms in the bulk liquid medium, and (d) the microorganisms attached to the solid media. The sensitivity of each of the four state variables to the various biological parameters, and system design variables, were investigated at steady state conditions. The theoretical model was verified by conducting experiments under steady and unsteady state conditions, using a pilot scale fluidized bed reactor treating synthetic wastewater. The experimental data obtained were compared to the predicted values calculated from the proposed theoretical model. The sensitivity analysis performed showed that the main factors affecting the process state variables are: the fluidization velocity, the size of the solid media used, the initial bed porosity, the specific yield, and the maximum rate of substrate utilization. The discrepancy between the steady state experimental data obtained, and the corresponding calculated theoretical values was quite large and significant. However, the discrepancy was much lower in the case of the unsteady state experiments. With further modifications and verifications, the proposed theoretical model can be adopted in comprehensive representation of the biological fluidized bed process.

This book was released on 2010 with total page 152 pages. Available in PDF, EPUB and Kindle. Book excerpt: Type II methanotrophic bacteria are superior to Type I methanotrophs in accumulating polyhydroxybutyrate (PHB), a biodegradable alternative to polypropylene and other petro-chemical plastics, under nutrient limiting conditions. We evaluated the growth of Type I and Type II methanotrophs in a 15.2-liter bench-scale fluidized bed reactor (FBR) over a 270-day period. The aim was to identify operational characteristics and selection pressures that would favor Type II over Type I methanotrophs. The results indicate that Type II methanotrophs can be grown in an FBR under the appropriate conditions and that such a method may be a viable means of producing large quantities of biomass for PHB production.

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.

Book excerpt: This compilation presents the main results reported in literature regarding the application of the fluidized bed reactor in the fermentative production of hydrogen using different synthetic and complex substrates, such as: glucose, sucrose, xylose, sugarcane vinasse, cheese whey, cassava wastewater and glycerin.Additionally, the results of studies on the dry torrefaction process of various types of fluidized bed biomass in an inert gas medium are presented, as well as the results of studies on torrefaction in a fluidized bed in a gas medium, which produces a mixture of inert gas and oxygen.Using a fluidized bed reactor for activated carbon production, the effect of various process parameters such as particle size, fluidizing velocity, process time, static bed height, activation temperature and fluidizing medium are studied.The authors propose that the development and implementation of the suspended bed reactor is the most reasonable means to achieve promising catalytic hydrogenation.

Available in PDF, EPUB and Kindle. Book excerpt: Getting consistently high efficiency for biological nitrification during cold weather is an important problem that was stuided by operating and modeling a fluidized bed pilot plant. The pilot plant experiments, including some step change and impulse dynamic tests were encouraging, and a model has been used successfully to fit both steady-state and dynamic performance data. The calibration runs indicated that the kinetic model, which includes rate limitations from several substrates and intraparticle diffusion, adequately describes the rate of substrate flux into the bioparticles. Alkalinity, pH, and nitrate data give good verification of the steady state prediction. The values of parameters used to fit the experimental data seem typical and their trends with time can be qualitatively explained. The parameters obtained in the steady state runs were used to successfully simulate the dynamic experiments. The results of these dynamic experiments lend general validity to the theoretical approach and provide a basis for further work to eliminate the uncertainty incorporated in the fitting parameters.
