Chemically enhanced separation of H2S04/HI mixtures from the bunsen reaction in the sulfur−iodine thermochemical cycle

Vincenzo Barbarossa, Auteur ; Giuseppina Vanga, Auteur ; Maurizio Diamanti, Auteur |

Dans Industrial & engineering chemistry research (Vol. 48 N° 19, Octobre 2009)

The Bunsen reaction identifies the chemical formation of sulfuric acid and hydriodic acid when sulfur dioxide is oxidized by molecular iodine in aqueous solutions. This reaction occurs spontaneously in a temperature range of 293−373 K and is one[...]

Study of I−/I2 poisoning of fe2O3-based catalysts for the h2SO4 decomposition in the sulfur−iodine cycle for hydrogen production

Vincenzo Barbarossa, Auteur ; Sergio Brutti, Auteur ; Bruno Brunetti ; Maurizio Diamanti, Auteur |

Dans Industrial & engineering chemistry research (Vol. 48 N°2, Janvier 2009)

The poisoning effect of I−/I2 mixtures on ferrous oxide based catalysts was investigated. These catalysts were used in the sulfuric acid thermal decomposition that is the highest endothermic step in the sulfur−iodine thermochemical cycle for hyd[...]
