Fixed Bed Reactor an overview ScienceDirect Topics

Using a fluidized bed reactor (Fig. 6.3) resolves some of the problems faced with a fixed bed reactor.This particular reactor offers a much more enhanced mass and heat transfer and minimizes temperature gradients throughout the reactor [64].The mass and heat transfer are improved due to better mixing of the catalyst with the fluid, which provides a greater surface area for the reaction to occur.

bed is fluidized and the pressure drop does not change appreciably. Also, record the corresponding bed height at each flow rate. Continue the measurements until the bed is appreciably fluidized and obtain at least fifteen readings in the packed-bed region and ten readings in the fluidized-bed region.

Fixed and Fluidized Beds

Fixed Bed. At high enough velocities fluid drag plus buoyancy overcomes the gravity force and the bed expands. Fluidized Bed. Low Velocity High Velocity p for Increasing u0 Until onset of fluidization p increases, then becomes constant. Bed Length for Increasing u0 L is constant until onset of fluidization and then begins to increase.
