The reactor consists in essence of a container filled with catalyst particles. These particles can be contained within a supporting structure, like tubes or channels, or they can be packed in one single compartment in the reactor. One of the most common reactors in the chemical industry, for use in heterogeneous catalytic processes, is the packed bed reactor. This type of reactor is used both in synthesis as well as in effluent treatment and catalytic combustion.
