unconventional reactors. 2. Fixed Bed Reactor Figure 1: Packed Bed Reactor A 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
The fixed bed reactor has been widely used in chemical reaction, combination, separation and concentration. Different heating or cooling liquids, such as water or oil, can be injected in the interlayer of 1L lab glass reactor for providing a constant temperature for reactions.
Fixed Bed Reactors In a fixed-bed reactor, the reagent flows over a stationary bed of packed catalyst (Towler and Sinnott, 2013). This is the most common type of reactor used for heterogeneous catalysis as long as the catalyst does not require continuous regeneration and the reaction mixture does not require high agitation (Towler, 2012).

The process is broken down into five sections. To begin, the reactor section (Section 100), consists of an ethane feed stream and two recycles from the separation sections. The feed is mixed with the recycles and then heated before entering a gas-phase, fixed-bed, catalytic reactor at 1150°F. The reactor houses 26 separate reactions.
