Publication number: 20240017236Abstract: A reactor includes a second flow path on a permeation side of a separation membrane. The second flow path includes an inflow port open to a first space between a first seal portion and a flow rate adjustment unit, and an outflow port open to a second space between a second seal portion and a flow rate adjustment unit. A housing includes a sweep gas supply port for supplying a sweep gas to the first space and a sweep gas exhaust port for discharging the sweep gas from the second space. In a side view of the reactor, a direction in which the sweep gas flows from the first space to the second space via the flow rate adjustment unit is the same as a direction in which the sweep gas flows through the second flow path.Type: ApplicationFiled: September 26, 2023Publication date: January 18, 2024Applicant: NGK INSULATORS, LTD.Inventors: Kosuke NAKAGAWA, Kazuki IIDA, Hirofumi KAN, Atsushi TORII, Makoto SHIOMI, Yukinari SHIBAGAKI, Katsuya SHIMIZU
