Several techniques can be employed to control mixing intensity in catalytic reactors:
1. Agitators and Stirring Devices: These are mechanical devices used to induce mixing in batch reactors. The design of the agitator, such as impellers or turbines, and the speed of rotation can be adjusted to achieve the desired mixing intensity.
2. Baffled Vessels: Baffles are obstructions placed in the reactor to break the flow pattern and enhance mixing. This is commonly used in stirred tank reactors.
3. Pumped Circulation: In continuous flow reactors, pumped circulation can be used to enhance mixing by recirculating the reactants through the reactor volume.
4. Jet Mixing: Utilizing high-velocity jets to mix reactants can achieve high mixing intensity, often employed in large-scale reactors.
