Synthesis Gas Production with Simultaneous CO2 Capturing and Consuming: Application of Chemical Looping Combustion by Employing Fe45-Al2O3 and Mn40/Mg-ZrO2 Oxygen Carriers

摘要

In this study, thermal coupling of chemical looping combustion (CLC) and dry reforming of methane (DR) via employment of Fe45-Al2O3 and Mn40/Mg-ZrO2 oxygen carriers (OCs) were investigated. The main aim of this configuration (CLC-DR) is the prevention of large CO2 emissions to the atmosphere by CLC and simultaneous consumption of the captured gas to synthesis gas through a DR reaction. For this purpose, a steady state one-dimensional heterogeneous catalytic reaction model is applied to analyze the performance and applicability of the proposed CLC-DR configuration using both OCs. Simulation results indicate that for both OCs, combustion efficiency reaches 1 in the fuel reactor (FR) of CLC-DR. Additionally, results illustrate that CH4 conversion in the DR side of CLC-DR reaches 0.7235 and 0.7213 with Fe45-Al2O3 and Mn40/Mg-ZrO2 OCs respectively.
