Chemical reactors - Essential Chemical Industry

Tubular reactors are used, for example, in the steam cracking of ethane, propane and butane and naphtha to produce alkenes. (b) Fixed bed reactors. A heterogeneous catalyst is used frequently in industry where gases flow through a solid catalyst (which is often in the form of small pellets to increase the surface area).It is often described as a fixed bed of catalyst (Figure 5).

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 advantage of the packed-bed reactor is that for most reactions it gives the highest conversion per weight of catalyst of any catalytic reactor. Another type of catalytic reactor in common use is the fluidized-bed reactor, which is analogous to the CSTR in that its contents, though heterogeneous, are well mixed, resulting in an even .
