MODELING AND SIMULATION OF SOLAR THERMAL DECOMPOSITION SULFUR TRIOXIDE REACTOR FOR HYDROGEN GENERATION

Solar energy is estimated to contribute a main part in the manufacture of prospect carrying fuels. In Particular, solar thermo chemical processes present the possible of extremely efficient mass hydrogen manufacture at a competitive price. Although the majority of these processes hold been evaluated in hypothetical studies, the skill is not yet prepared for claim. The peak universal priority is presently the sulfur-based cycles, i.e., the sulfur-iodine (SI) cycle, since they can be operating at temperature at which it is feasible to use rigorous solar radiation as the process heat resource. However, high temperatures and corrosive environments in their enter steps current key challenges. The rigorous operating circumstances require advanced resources as fine as particular design and production methods for input components regular to (SI) cycles, including oxygen separator, H2SO4 evaporator, and sulfur trioxide (SO3) decomposer. The last has to survive the maximum temperature in the cycles, which is over 850°C. In current study a directly heated SO3 packed bed decomposer used for the S-I cycle will be analyzed for the action at the focus of three meter diameter paraboloid dish and using the outer source of concentrated thermal radiation meant for high temperature as system heat. Spherical pellet of the size 4mm, 5mm and 6mm are arranged inside the packed bed region. Several aspects of the preparation are model used for scaling the system up: the heat move and its cause on the integrity of the resources, and the fluid flow of all gas streams inside the reactor by using computational fluid dynamics (CFD)
