Chemical looping reactor for sustainable chemical synthesis with CO2 capture

该项目的主要目标是开发一个全面的反应器模型，用于设计和放大使用动态操作的固定床布局的化学环流反应器，该反应器能够生产具有固有二氧化碳捕集功能的合成气。在现有模型的基础上，本项目将尝试将2D唯象模型与CFD分析相结合，并将其用于小型和大型装置的设计。具体目标如下：1)在2D反应器模型的基础上建立唯象模型，该模型将考虑不同技术的应用(如化学环重整、逆水煤气变换、化学环与汽铁结合)，包括质量、动量和传热现象的影响。2)建立了气固反应动力学模型和时空离散化模型相结合的CFD反应器模型。在这种情况下，商业软件也将被用来为工业伙伴提供进一步使用的工具。3)为选定的感兴趣的应用设计综合化学循环工艺，包括使用天然气、沼气、可再生能源H2和CO2、废物副产品、富含二氧化碳的蒸气和废气，并评估技术经济绩效。4)通过测试曼彻斯特大学提供的实验室规模的反应堆单元，对反应堆模型进行实验验证。该项目与EPSRC的工艺工程、氢气生产和二氧化碳捕获和储存相关

The main objective of this project is the development of a comprehensive reactor model for the design and scale-up of the chemical looping reactor using dynamically operated fixed bed layout capable of producing syngas with inherent CO2 capture. With respect to the existing modelling, this project will attempt the combination of 2D phenomenological model and CFD analysis and use it for the design of a small and large-scale units.The specific objectives are reported below:1) Development of phenomenological model based on 2D reactor modelling which would include the effect of mass, momentum and heat transfer phenomena by considering different uses of the technologies (e.g. chemical looping reforming, reverse water gas shift, chemical looping integrated with steam-iron). 2) Development of a CFD reactor model integrating gas-solid reaction kinetic model and time-space discretisation model. In this case, a commercial software will be used to provide also a tool to the industrial partner for further uses.3) Design of the integrated chemical looping process for the selected applications of interest including the use of natural gas, biogas, renewables H2 and CO2, waste by-products, CO2-rich streams and waste offgas and assess the techno-economic performance. 4) Experimental validation of the reactor models by testing the lab scale reactor unit available at the University of Manchester. This project is relevant with the EPSRC remit of process engineering, hydrogen production and CO2 capture and storage
