Modeling of the Aerodisperse Systems Hydrodynamics in Devices With Directional Motion of the Fluidized Bed

The work is devoted to the using of modern program packages for simulation of the aerodisperse systems hydrodynamics of equipment with directional motion of the fluidized bed for the chemical industry. The criteria for selecting the design for this type of equipment are substantiated. New forms of organization of flow motion in the fluidized bed regime are proposed. The mechanisms of motion and residence time control of the disperse phase in the working space of the devices are described. The results of computer simulation of hydrodynamic conditions of the directed gas stream and a two-phase aerodisperse system motion are presented. An algorithm for optimizing the calculation of equipment based on the results of computer simulation (by example of the unit for the porous ammonium nitrate with nanostructured porous layers production) is shown.

Control of tandem isomerizations: flow-assisted reactions of o-lithiated aryl benzyl ethers

We report a flow microreactor platform for controlling tandem isomerizations of o-lithiated aryl benzyl ethers based on precise residence time control.
