WebA chemical reactor is an enclosed volume in which a chemical reaction takes place. In chemical ... A tubular reactor can often be a packed bed. In this case, the tube or channel contains particles or pellets, usually a solid catalyst. The reactants, in liquid or gas phase, are pumped through the catalyst bed. Web1. Packed bed reactor apparatus for treatment of wastewater by aerobic bacterial action, including tank means containing a horizontally and vertically extending bed of particulate medium capable of supporting aerobic bacterial growth, and outlet means for removing the treated wastewater from the upper portion of said tank, wherein the improvement is …
WebPacked bed reactors consist of a cylindrical shell with convex heads. Most are vertical, and allow reactants to flow by gravity. Inside the reactor is an immobilized, or fixed, bed of … WebA real plug flow reactor has a residence time distribution that is a narrow pulse around the mean residence time distribution. A typical plug flow reactor could be a tube packed with some solid material (frequently a catalyst). Typically these types of reactors are called packed bed reactors or PBR's.

WebA fluidized bed reactor ( FBR) is a type of reactor device that can be used to carry out a variety of multiphase chemical reactions. In this type of reactor, a fluid (gas or liquid) is passed through a solid granular material (usually a catalyst) at high enough speeds to suspend the solid and cause it to behave as though it were a fluid.
In chemical processing, a packed bed is a hollow tube, pipe, or other vessel that is filled with a packing material. The packing can be randomly filled with small objects like Raschig rings or else it can be a specifically designed structured packing.
