چکیده

In this study, the production of H2 utilizing chemical looping combustion (CLC) in a methane dry reformer assisted by H2 perm-selective membranes in a CLC-DRM configuration has been investigated. CLC via employment of a Mn-based oxygen carrier generates large amounts of heat in addition to providing CO2 as the raw material for the dry reforming (DR) reaction. The main advantage of the CLC-DRM configuration is the simultaneous capturing and consuming of CO2 as a greenhouse gas for H2 production. A steady state one dimensional heterogeneous catalytic reaction model is applied to analyze the performance and applicability of the proposed CLC-DRM configuration. Simulation results show that CH4 is completely consumed in the fuel reactor (FR) of the CLC-DRM and pure CO2 is captured by condensation of H2O. Also, CH4 conversion and H2 yield reach 73.46% and 1.459 respectively at the outlet of the DR side in the CLC-DRM. Additionally, 4562 kmol h?1 H2 is produced in the DR side of the CLC-DRM. Finally, results indicate that by increasing the FR feed temperature up to 880 K, CH4 conversion and H2 production are enhanced to 81.15% and 4790 kmol h?1 respectively.
