This study presents a thermodynamic analysis of novel concept that synergistically integrates solid oxide fuel cell with Ceria-based solar-chemical looping methane reforming system. The integrated configuration aims to simultaneously achieve solar energy storage, electric power production, carbon capture and in situ re-utilization. proposed hybrid system capitalises on the advantageous features unit, specifically oxygen carrier reduction during step for waste gas dissociation oxidation release. additional syngas produced is introduced cell, enabling further production stream schematic process modelled by solving mass balances at steady-state conditions. chemical parameters (fuel ratio, co-splitting ratio), material (Ceria effectiveness), (temperature, utilisation, operating voltage, steam-to-carbon ratio) are also examined. plant exhibits promising characteristics, achieving high electrical global efficiencies (63.6 % 70 %, respectively), density (404 kWh/m3) partial dioxide re-utilization net zero emissions.

Review on Migration and Transformation of Lattice Oxygen during Chemical Looping Conversion: Advances and Perspectives

Energy & Fuels, Journal Year: 2023, Volume and Issue: 37(8), P. 5743 - 5756

Published: March 30, 2023

Chemical looping technology is one of the most promising approaches in fields fuel conversion, pollution removal, energy conservation, and carbon dioxide capture utilization has been extensively investigated for more than two decades. A majority chemical process achieved through migration transformation lattice oxygen. Thus, exploring oxygen critical to clarify looping's reaction rules allow further control selectivity yield. Herein, recent advances exploration oxygen's mechanism are systematically reviewed, with a focus on structure–activity relationships. The great roles that characterization techniques perform address challenges activities discussed first. We then outline categories carrier materials Lastly, research directions design high-performance carriers well-regulated activity redox overviewed. infer relationship between target products challenging but essential─it direction worthy our efforts future.

Economic model predictive control for packed bed chemical looping combustion

Chemical Engineering and Processing - Process Intensification, Journal Year: 2024, Volume and Issue: 198, P. 109731 - 109731

Published: March 6, 2024

This study presents an economic model predictive control (EMPC) scheme for the packed-bed reactor (PBR) design of a chemical looping combustion (CLC) system. is enabled by pseudo-homogeneous process model, which accurately represents macroscopic behaviour, and enables economics to be optimized online. Both CLC stages are whereby oxidation stage considers energy generation inert gas use, while reduction economizes CO2 production fuel use. To understand behaviour EMPC, tested on plant represented multi-scale model. under varying initial inlets, prices, carbon prices. The optimal policy found that maximal peak temperature, where EMPC results in revenue standard NMPC controller may result losses. highly dependent prices trade-off between selectivity throughput observed. approach economically superior advanced regulatory with up order-of-magnitude ∼33% improvements stages, respectively. step forward towards adoption intensified PBR as emerging viable technology heat inherent capture.
