Flexible strategies for carbon‐negative syngas and biochar poly‐generation via a novel chemical looping approach

AIChE Journal, Год журнала: 2024, Номер 70(11)

Опубликована: Авг. 12, 2024

Abstract This work proposed a pyrolysis chemical looping reforming‐two stage regeneration (PCLR‐TR) process with carbon‐negative syngas and biochar poly‐generation，aimed at overcoming challenges in gasification. The effectively separates reforming, circumventing slow solid–solid reactions enabling the flexible adjustment of H 2 /CO ratio. two‐stage ensures improved synchronization reaction rates across different reactors. results indicate that manipulation parameters allows for ratio (ranging from 1.02 to 3.83). introduction CO feed first reactor reduces oxygen carrier exothermic intensity second by 58%. Optimization suggest generated is compatible diverse downstream applications, exhibiting maximum negative emission 1.85 kg/kg syngas. PCLR‐TR system offers versatile environmentally friendly solution energy industries.

Collaborative modelling of Gas-Solid reacting flow in a fuel reactor equipped with process controllers in chemical looping Combustion/Conversion

Chemical Engineering Journal, Год журнала: 2024, Номер 497, С. 154437 - 154437

Chemical reactors usually feature complex internal reacting flows, and they are equipped with process controllers to stabilise their operations, especially for highly dynamic including chemical looping combustion/conversion (CLC). However, states not well understood due the lack of reliable research tools. In this work, first time, an innovative numerical collaborative model is developed describe flow details simulate response a controller. The applied fuel reactor (FR) in CLC demonstrate its effectiveness. detailed patterns FR obtained described by three-phase CFD model, circulating rate oxygen carrier (OC) controlled optimised fuzzy logic controller (FLC). designed operate at varying control time intervals, 1 s, 2 5 study optimal frequency data sampling feedback. efficiency tested terms OC circulation, gas components general performance reactor. results show that stability effectively improved controller; among three s interval shows highest feasibility capability maintaining stable circulation CO2 yield FR. Quantitatively, compared base case without controller, range rates has been narrowed from [0.014, 0.534] [0.018, 0.385] A, [0.075, 0.342] B, [0.004, 0.530] C. Meanwhile, increased 86.93 % 87.98 88.16 but decreased 85.4 C poor controlling performance. combustion 84.20 84.87 86.22 85.88 Among all cases, B presents narrowest efficiency, indicating improving stability. deviation values decreases 0.123 0.058, increases interval. This work provides new cost-effective tool real-time simulating system clean solid wastes conversion.
