    dct:description """
              The following reactions: <br /><br /> (1) H<sub>2</sub>S + H<sub>2</sub>SO<sub>4</sub> → SO<sub>2</sub> + S + 2H<sub>2</sub>O<br /><br /> (2) S + O<sub>2</sub> → O<sub>2</sub><br /><br /> (3) 2SO<sub>2</sub> + 4H<sub>2</sub>O + 2I<sub>2</sub> → 2H<sub>2</sub>SO<sub>4</sub> + 4HI<br /><br /> (4) 4HI → 2H<sub>2</sub> + 2I<sub>2</sub><br /><br /> form a H<sub>2</sub>S chemical splitting cycle that converts 1 mol H<sub>2</sub>S into 2 mol of H<sub>2</sub>. This makes it possible to provide hydrogen in upgrading the Canadian oil sands bitumen from processing its waste product H<sub>2</sub>S. To engineer the chemistry, process design and experiments on reactions and separations are under investigation. In this paper, efforts have been made in order to have reactions 1, 3 and 4 be conducted at ambient temperatures and in fluid medium, thus minimizing side reactions, corrosiveness and other process difficulties and making the separations of products easier. The results show that the separation of the elemetal sulfur from the spent sulfuric acid after reaction 1 can be done by phase separation, that using the I<sub>2</sub>-toluene solution can make the Bunsen reaction (reaction 3) take place below the melting point of iodine, and that the direct electrolysis of HI solution from the product of reaction 3 leads to the production of H<sub>2</sub> at room temperature through reaction 4.
