The residence time distribution of the gas phase in circulating fluidized beds (CFB)
CFB reactors are increasingly used for both gas catalytic and gas/solid reactions. Gas flow patterns in the riser are important in their design and subject of the present research. A literature review on the gas mixing in the riser highlights the contradictory results of previous investigations for CFB risers: some investigators neglected back-mixing of gas, whereas others report a considerable...
متن کاملFlow through Packed Beds and Fluidized Beds
Chemical engineering operations commonly involve the use of packed and fluidized beds. These are devices in which a large surface area for contact between a liquid and a gas (absorption, distillation) or a solid and a gas or liquid (adsorption, catalysis) is obtained for achieving rapid mass and heat transfer, and particularly in the case of fluidized beds, catalytic chemical reactions. You wil...
متن کاملMultiscale probability distribution of pressure fluctuations in fluidized beds
Analysis of flow in fluidized beds, a common chemical reactor, is of much current interest due to its fundamental as well as industrial importance. Experimental data for the successive increments of the pressure fluctuations time series in a fluidized bed are analyzed by computing a multiscale probability density function (PDF) of the increments. The results demonstrate the evolution of the sha...
متن کاملThe Influence of Particle Residence Time Distribution on the Reactivity in Fluidized Bed Reactors
The influence of particle residence time distribution on the average conversion rate (or reactivity) of particles undergoing a non-catalytic gas-solid reaction inside a continuously operated fluidized bed reactor is evaluated. A so-called &factor is defined as the ratio of the actual reactivity in the reactor and the reactivity of a batch of particles that react under similar circumstances and ...
متن کاملDynamic Behavior of Local Solids Concentration in Fluidized Beds: Experimental Validation of an Eulerian-Eulerian Model
Recent years have witnessed significant improvements in the computer modeling of fluidized particle systems. Such models hold the potential to simulate complex systems and thus greatly reduce design efforts. As we approach the goal of simulating arbitrary systems, there exists a greater need to challenge the ability of the models to predict key features of operating beds. The simplest challenge...
