  • Heat exchanger-integrated reaction device having supplying and return ducts for reaction section
    Patent number: 8574507
    Abstract: A compact heat exchanger-integrated reaction device, comprising a heat exchange section and a reaction section, capable of providing high heat recovery performance, with a small number of ducts of the reaction section formed for supplying and return paths without increasing the volume of the entire reaction device. With the heat exchanger-integrated reaction device equipped with ducts in the reaction section adjacent to the plate-stacking-type heat exchange section, collection ducts for allowing a plurality of regions having openings for discharging a fluid to be processed to be connected with at least one supplying duct of the reaction section, and distribution ducts for allowing at least one supplying duct of the reaction section to be connected with a plurality of regions having openings for receiving the fluid from the heat exchange section are provided between the heat exchange section and the duct of the reaction section.
    Type: Grant
