Abstract
PURPOSE: To efficiently produce H2 and O2 from Sb2O3 and I2 as starting raw materials by carrying out multistage thermal decomposition due to fresh chemical reactions using CaO and water.
CONSTITUTION: A) Pulverized Sb2O3 and excess I2 are contacted at 500W800°K to form SbI3 and Sb2O4. B) The liquid phase SbI3 separated in the process A and 0.25W4 times as much CaO as the SbI3 by mol are reacted at 633°K, and CaI2 is separated from the resulting solid reaction product consisting of CaI2 and Sb2O3 by making use of a vapor press. difference. C) The liquid phase CaI2 separated in the process B and steam are contacted at above 900°K to form CaO and HI. D) The HI separated in the process C is separated into H2 and I2 usually at above 500°K. E) The Sb2O4 formed in the process A is thermally decomposed into Sb2O3 and O2 under an inert gas stream such as N2 usually at above 1200°K to form Sb2O3 and O2, and the Sb2O3 is recycled to the process A.
