dc.description.abstractChemical looping syngas production is a two-step syngas fuel production process that produces CO and H 2 . The process is composed of two fluidized bed reactors (oxidation reaction and reduction reactor), oxygen carriers (metal oxides) circulating between the two reactors. A comprehensive model is developed to simulate the chemical looping water and carbon dioxide splitting in a dual fluidized bed reactors interconnected with redox cycling between these two reactors through metal oxides (non-stoichiometric ceria). An extensive FORTRAN subroutine is developed and hooked into Aspen plus V8.8 to appropriately model the complexities of the bubbling fluidized bed reactor including the reaction kinetics. The model developed has been validated for its hydrodynamics and kinetics level and individual correlation was quantified for its validity. The reduction reactor is maintained between the temperatures 1300-1500°C. The heat to attain this high temperature can be achieved with solar beam down tower. The oxidation reactor is supplied with a mixture of CO 2 and H 2 O with different mixture composition combining 60% and remaining N 2 . The oxidation reactor temperature is varied between 700-1000°C to identify the maximum efficiency achieved. It is found that the maximum efficiency achieved is 67.4% corresponding to highest temperature difference between the reactors.
