HEAT EXCHANGE REACTOR FOR PRODUCING HYDROGEN USING BUILT-IN STEAM GENERATOR BEAM Russian patent published in 2016 - IPC B01J19/24 F22B33/18 F22B1/18 F28F1/00 F28F13/00 F28D5/00 

FIELD: chemistry.

SUBSTANCE: invention is intended for implementation of steam reforming reactions and can be used in chemical industry. Heat exchange reactor comprises multiple bayonet pipes (4), suspended from upper hood (2), extending to level of lower bottom (3) and enclosed in casing (1), having inlet (E) and outlet (S) pipes for flue gases. Heat exchange reactor comprises buttle of pipes of steam generator, formed by multiple vertical pipes (5), suspended from upper hood (2) and enclosed into peripheral space between inner partition (Bi) and vertical wall of casing (1). Inner partition (Bi) comprises a hole (Oi) for passage of flue gases from middle of reactor to peripheral space. Vertical pipes (5) are fed with water from lower distributor (9). Water-steam mixture coming out of vertical pipes (5), is collected in upper collector (7) located above upper hood (2). Lower line (14) connects liquid phase of separation reservoir (6) with upper collector (7). Upper line (13) connects upper collector (7) with steam phase of separation reservoir (6). Steam reforming is carried out at a rate of flue gases in peripheral space from 20 m/s to 80 m/s. Flue gases are fed into heat exchange reactor at temperature close to 1,200 °C, and exit it at temperature below 400 °C.

EFFECT: invention improves heat efficiency of heat exchange reactor.
