Micro reactors typically consist of a network of microchannels through which reactants flow continuously. The walls of these channels can be coated with a catalyst, or catalysts can be mixed with the reactants in a homogeneous system. The design of the microchannels ensures that the reactants are in close contact with the catalyst, enhancing the reaction efficiency. Parameters such as flow rate, temperature, and pressure can be precisely controlled using integrated sensors and actuators.
