Chemical reactor

A chemical reactor, typically tubular reactor, could be a packed bed. The packing inside the bed may have catalyst to catalyze the chemical reaction. A chemical reactor may also be a fluidized bed; see Fluidized bed reactor. Chemical reactions occurring in a reactor may be exothermic, meaning giving off heat, or endothermic, meaning absorbing .

May 30, 2019 · Ebullated bed reactors are a type of fluidized bed reactor that utilizes ebullition, or bubbling, to achieve appropriate distribution of reactants and catalysts. The ebullated-bed technology utilizes a three-phase reactor, and is most applicable for exothermic reactions and for feedstocks which are difficult to process in fixed-bed or plug flow .

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).

Chemical reactor - Wikipedia

A chemical reactor is an enclosed volume in which a chemical reaction takes place. In chemical engineering, it is generally understood to be a process vessel used to carry out a chemical reaction, which is one of the classic unit operations in chemical process analysis. The design of a chemical reactor deals with multiple aspects of chemical engineering.
