FIELD: chemical industry. SUBSTANCE: apparatus has mounted in accordance with technological scheme of process bunker with initial component, tank for water, cylinder to keep ready-made product (hydrogen), heat generator to provide corresponding temperature modes of thermochemical cycles, connected to heat generator by heat carriers oxidation reactor and reduction reactor, connected to each other by system of transportation of initial components, intermediate products of thermochemical cycles and ready-made product, locking and adjusting tools and also capacity for catalyst (iodine) and cylinder to keep oxygen. In the case, oxidation reactor has mixing device, that is made as piston and set of perforated disks, mounted on kinematically linked with vibrator rods and located in reactor liquid phase zone. Reduction reactor is made in the form of two vertical columns, mounted in vertical plane with shift upward in respect to oxidation reactor and connected by common spiral branch of transportation system, input of which is through additionally mounted heat exchanger connected with oxidation reactor through pressure hydraulic main. Output of the transportation system is made directly in oxidation reactor. Inside transportation system there is helical-type tube, that i also connected to heat generator by heat carrier. The tube links oxidation reactor gas phase zone through transportation mains with cylinder to keep ready-made product (hydrogen) or directly with consumer and through heat exchanger with main of catalyst feeding-retracting into oxidation reactor. Reduction reactor inner cavity of production process running first vertical column is linked through condenser by main with tank for water and inner cavity of second column through additional absorbers is linked by main with cylinder to keep oxygen or directly with consumer. Oxidation reactor is also linked bu mains with bunker to keep initial component and with tank for catalyst. EFFECT: apparatus is used in chemical industry. 6 cl, 3 dwg
