摘要： 准确且合理的能耗分析对碳捕集技术规模化发展至关重要，其既是碳捕集技术节能降耗的必要前期准备，也是碳捕集过程开展绿色化、清洁化性能评价的重要数据基础。因此，在对碳捕集过程的能源转换共性展开探索的同时，迫切需要面向工程实践的需求，形成易于操作的能效性能对标分析方法，从而保证对类型技术的性能认知可以在合理且统一的评价平台上进行归纳与比较。本工作基于对标分析(Benchmarking Analysis)方法，对变温吸附碳捕集(TSA)过程的能耗分析方法进行了阐述，包括流程、参数、模型等。研究了吸附温度和解吸温度对TSA能效性能结果的影响，演示并量化了该方法的可行性，重点对边界变化对评价结果的影响进行了讨论。提出的对标分析方法对碳捕集技术的能效性能对标评估给出了较具体的指导。

Abstract: An accurate and reasonable energy efficiency analysis is significant to the scale-up development of carbon capture technology. It is not only a preliminary preparation to the final energy-saving proposal of carbon capture technology, but also an important data basis to sustainable performance evaluation of carbon capture process with aims on green, clean and low-carbon. Therefore, in addition to exploring the mechanism on energy conversion of carbon capture process, it is urgent to establish a benchmarking analysis methodology of energy efficiency performance which features on easy-to-operate for the demand of engineering sector, so that the performance cognition of typical capture technologies could be accumulated and compared on a reasonable and unified evaluation platform. Based on the benchmarking analysis method, the methodology of energy efficiency performance on temperature swing adsorption (TSA) is presented, including processes, parameters, model, etc. The effect of adsorption temperature and desorption temperature on the energy efficiency performance of TSA was analyzed, the feasibility of proposed method is demonstrated and quantified, and the influence of boundary changes on the evaluation results was discussed as well. The proposed method could provide a generalized guidance to the benchmarking evaluation of energy efficiency performance of carbon capture with specific case.
