چکیده انگلیسی
The Bunsen reaction section of I-S cycle has two parts, reaction and phase separation. Some previous work focused on phase separation using a simulated reaction mixture with four components (H2SO4, HI, H2O and I2). Based on phase separation data an operating window was suggested. This previous work had the limitation that reaction was not included. The present work includes both reaction and separation. We demonstrated that the Bunsen reaction ratio is higher than 2, and the azeotropic ratio(mol of HI/mol of HIÂ +Â H2O) is higher than 0.4Â at 293Â K and 2Â mol of I2 in the feed. Bunsen reaction was promoted at a lower temperature and higher I2 content, while phase separation became worse since the generated H2SO4 and HI remained in the HIx phase without separation. We validated the previously suggested optimal window and examined phase separation at the lower temperature region.
