[0002] A reactor is broadly understood as a container for physical or chemical reactions. Through the structural design and parameter configuration of the container, the heating, evaporation, cooling and low-speed mixing functions required by the process can be achieved.

[0003] During the process of material reaction in the reactor, it is sometimes necessary to add a catalyst into the reactor to speed up the reaction rate of the materials inside the reactor. In conventional reactors, the catalyst can only be added when the reactor is opened. Under the condition of less reaction liquid, the catalyst can only react with the catalyst near the bottom of the reactor. The catalyst utilization rate is low, and the reaction between the catalyst and the reaction liquid is not sufficient.

[0004] To this end, we proposed a micro horizontal reactor in which the stirring paddle can carry the catalyst. Utility Model Content
