Abstract
1486042 Hydrogen and oxygen from water RHEINISCHE BRAUNKOHLENWERKE AG 14 July 1975 [15 July 1974] 29495/75 Heading C1A Hydrogen and oxygen are produced from water in a cyclic process conducted in the range 200‹ to 1100‹ C. comprising (a) reacting Fe 2 O 4 with (i) clorine with or without water, or (ii) FeCl 3 withor without H 2 in one process step at between 350‹ and 1100‹ C. to form FeO, Fe 2 O 3 or FeCl 2 and recovering the products, (b) reforming the starting materials for (a) in at least three additional process steps involving suitable reactants selected from FeO, Fe 2 O 3 , Fe 2 O 4 , FeCl 2 , FeCl 3 , Cl 2 , HCl, H 2 O, H 2 and O 2 at a temperature from 200‹ to 1100‹ C. and recycling the starting materials for use in process step (a) wherein FeO or H 2 O is reacted with Cl 2 in one of the additional steps to yield free O 2 , and FeCl 2 or FeO is reacted with H 2 O in a further step to obtain free H 2 , and, (c) separately recovering at least part of the H 2 and O 2 as product gases.
