چکیده

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. Results show that application of CLC-DR employing Fe45-Al2O3 and Mn40/Mg–ZrO2 OCs produces 8611 and 8585 kmol h1 of synthesis gas, respectively. Synthesis gases with H2/CO mole ratios of 0.9519 and 0.9612 are achieved using Fe45-Al2O3 and Mn40/Mg–ZrO2 OCs respectively. In addition, results demonstrate that by increasing the feed temperature of CLC-DR from 800 to 1000 K, synthesis gas production reaches 11 210 and 11 340 kmol h1 when using Fe45-Al2O3 and Mn40/Mg–ZrO2, respectively. Finally, thermal and molar behaviours of CLC-DR configuration indicate that it is applicable, and by utilization of this configuration 547.8 tonne day1 can be captured and converted to synthesis gas.
