Abstract
1442950 Hydrogen production EUROPEAN ATOMIC ENERGY COMMUNITY 13 Nov 1974 [12 Dec 1973] 49080/74 Heading C1A Hydrogen is produced from water by means of a cycle of chemical reactions which involve the decomposition of a hydrogen-containing salt of HI and a weak base, e.g. ammonium iodide. The preferred process comprises the following steps: (i) the dissociation of NH 4 I into NH 3 , H 2 and I 2 (ii) the reduction of the I 2 thus formed with SO 2 , H 2 O and NH 3 to produce NH 4 I and (NH 4 ) 2 SO 4 ; (iii) the reaction of the (NH 4 ) 2 SO 4 with Na 2 SO 4 to produced NaHSO 4 and NH 3 , (iv) the decomposition of the NaHSO 4 to give Na 2 S 2 O 7 and H 2 O; (v) the dissociation of the Na 2 S 2 O 7 to produce Na 2 SO 4 and SO 3 ; (vi) the dissociation of the SO 3 to give SO 2 and O 2 ; (vii) the recycling of the NH 4 I of step (ii) to step (i); (viii) the recycling of the NH 3 of steps (i) and (iii) to step (ii); (ix) recycling the Na 2 SO 4 of step (v) to step (iii), and (x) recycling the SO 2 of step (vi) to step (ii).
