Abstract

The invention relates to a plant for production of hydrogen, and to a method for operating this plant, comprising a steam reforming reactor having a furnace, in which reactor water and at least one carbonaceous energy carrier are reacted to form a hydrogen-containing crude synthesis gas, and at least one cleaning device for purifying the crude synthesis gas, to which the crude synthesis gas is fed from the steam reforming via at least one feed line. According to the invention, upstream of one of the at least one cleaning devices at least one return line branches off from the feed line, through which the crude synthesis gas is at least in part recirculated into the furnace of the steam reforming reactor.
