Adsorption technologies provide high selectivity and low energy consumption making this technique very attractive to be employed in post-combustion carbon capture. In this publication, a material made of activated carbon and zeolite 13X is considered for a hybrid process termed Temperature Electric Swing Adsorption (T/ESA). This hybrid T/ESA can work as a traditional Temperature Swing Adsorption (TSA) heated by hot gas, but can also increase the temperature of the adsorbent very fast by Joule effect as long as the activated carbon provides a continuous conductive matrix for electricity. This paper discusses a detailed modeling of the T/ESA process when applied to three cases. The first case is the simulation of the T/ESA process with exhaust with 12% of CO₂ concentration, which has been chosen to validate the model against literature results. The second and third case studies consider the T/ESA application in a natural gas combined cycle (NGCC) traditional power plant, and in a NGCC plant with exhaust gas recycle (EGR). These cases were selected to investigate the adsorption technology at low CO₂ concentration and quantify the benefit of the EGR for carbon capture applications. Starting from an NGCC overall electric efficiency of 58.3% LHV based, the efficiency of the NGCC with T/ESA technology reduces to 35.3% while with EGR is 38.9% against the 49.9% with the MEA absorption plant. The same results are confirmed by the SPECCA index 13.05 MJ_LHV/kg_CO2 to 9.64 MJ_LHV/kg_CO2 against the reference of 3.36 MJ_LHV/kg_CO2. The energy penalty of the T/ESA is significant because of electric consumptions required for the heating and fast cooling of the adsorbent.

吸附技术提供了高选择性和低能耗，使该技术非常适合用于燃烧后碳捕集。在该出版物中，考虑将由活性炭和13X沸石制成的材料用于称为温度电摇摆吸附（T / ESA）的混合工艺。这种混合型T / ESA可以像传统的通过热气加热的变温吸附（TSA）一样工作，但是只要活性炭为电提供连续的导电基质，也可以通过焦耳效应非常快速地提高吸附剂的温度。本文讨论了将T / ESA流程应用于三种情况的详细模型。第一种情况是使用含12％CO _2的废气模拟T / ESA过程浓度，已被选择用来对照文献结果验证模型。第二个和第三个案例研究考虑了T / ESA在天然气联合循环（NGCC）传统发电厂以及带有废气再循环（EGR）的NGCC工厂中的应用。选择这些案例来研究低CO ₂浓度下的吸附技术，并量化EGR在碳捕集应用中的优势。从基于LHV的NGCC总电效率为58.3％开始，采用T / ESA技术的NGCC效率降至35.3％，而EGR为38.9％，而MEA吸收装置为49.9％。SPECCA指数从13.05 MJ _LHV / kg _CO2到9.64 MJ _LHV / kg _CO2证实了相同的结果相对于3.36 MJ _LHV / kg _CO2的参考。由于加热和快速冷却吸附剂需要消耗电能，因此T / ESA的能量消耗非常大。
