[0002] An external circulation reactor refers to a reactor in which the concentration gradient in the axial direction is zero or close to zero. The structure of an external circulation reactor is basically the same as that of a differential reactor, except that an external circulation pipe is added to recirculate the gas coming out of the reactor to the inlet through a circulation machine. Due to the recirculation of a large amount of gas, the purpose of isoconcentration operation is achieved.

[0003] However, the prior art still has the following problems:
