P&id of fixed bed reactor
WebA fixed or packed bed is an assembly of randomly arranged particles that are bathed by the reactant fluid, which flows in random manner around the pellets. A schematic representation of fixed bed reactor is shown in Figure 1. Catalytic fixed bed reactors find wide spread use in chemical industries. WebFixed bed. Fixed bed reactors have a catalyst bed that is held in place, as opposed to an ebullated bed or fluidized bed.. Consequently, the catalyst in fixed bed reactors cannot be drawn off and regenerated during operation, so it gradually and progressively deactivates as coke is produced as a reaction byproduct and enters and blocks the catalyst pores.

WebFixed-bed reactors involve highly complex, multi-variable processes. Maintaining optimum conditions inside the catalyst bed requires precise and instantaneous : response to temperature excursions, feedstock impurities, and other potential upsets. Emerson’s model-based advanced process control solution allows you to WebOne of the commonest applications of fixed bed pgm catalysts in the non-petrochemical Industries is to produce high purity gases. This uses pelleted catalysts generally comprising ≤ 0.5% by weight of pgm, supported on either ceramic extrudates, compressed tablets or spheres. With such a catalyst, traces of oxygen (O 2) can be removed from ...
