Impact of residence time distributions in reacting magnesium packed-beds on Grignard reagent formation – Pump-induced flow behaviour in non-reacting magnesium beds (part 1)
نویسندگان
چکیده
Grignard reagent formation in continuously operated magnesium packed-bed reactors can be influenced by finetuning the residence time distribution within packing. By decreasing turning size and increasing...

Flow 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 کاملTomography-Based Analysis of Radiative Transfer in Reacting Packed Beds Undergoing a Solid-Gas Thermochemical Transformation
A reacting packed-bed undergoing a high-temperature thermochemical solid-gas transformation is considered. The steamand dry-gasification of carbonaceous materials to syngas is selected as the model reaction. The exact 3D digital geometrical representation of the packed-bed is obtained by computer tomography and used in direct pore-level simulations to characterize its morphological and radiativ...
متن کاملToward Direct Numerical Simulation of Reacting Fluidized Beds
Nowadays, the most used techniques to design dense gas-solid flow reactors rely upon numerical predictions obtained from hydrodynamic models, usually derived through some averaging processes of the complete conservation equations. The averaging process leads to unknown correlation terms that need further modeling for the final closure of the equations. Many of these terms represent complex inte...
