Abstract
Anthropogenic activites release greenhouse gas emissions into our atmosphere, especially carbon dioxide (CO2 ). This abundant accumulation of CO2 generates numerous problems like global warming and climate change. However, research has been conducted to capture CO2 from significant single-point emitters like compression ignition (CI) engines, backup generators, and distributed power production plants. Moreover, research has also been done on post-combustion adsorption chamber to capture CO2 emissions from small stationary engines. Biomass-based activated carbon as an adsorbent for capturing CO2 from engine exhaust has recently been investigated. Three biomass-based adsorbents, (a) coconut shell adsorbent, (b) rice husk adsorbent and (c) eucalyptus wood adsorbent, are used in the capture unit to trap CO2 from the CI engine exhaust. This study uses a single-cylinder, four-stroke, air-cooled, naturally-aspirated, direct-injection (DI) CI engine running at a constant speed of 1,500 rpm and producing power of 4.4 kW. The adsorption performance of adsorbent samples is investigated by coupling the adsorption chamber to the exhaust system of a test engine operated on diesel (D100) at various loads. Temperature swing adsorption (TSA) is used to regenerate the original adsorbent. The adsorbents’ adsorption capacities are evaluated by performing multiple adsorption–desorption test cycles using the same adsorbents. During TSA, CO2 released from the capture unit is further captured and stored in a gas bag. The captured gas sample is characterized through gas chromatography-mass spectroscopy (GC-MS) characterization to examine and ensure the gas adsorption efficacy of adsorbent samples. The outcomes of this research study are discussed and presented in detail. © 2023 Society of Chemical Industry and John Wiley & Sons, Ltd.
利用 CI 发动机废气中的潜在吸附剂捕获二氧化碳的性能评估--实验研究
人类活动向大气排放温室气体,尤其是二氧化碳(CO2)。二氧化碳的大量积累引发了全球变暖和气候变化等诸多问题。然而,人们已经开始研究如何从压缩点火(CI)发动机、备用发电机和分布式发电厂等重要的单点排放源中捕获二氧化碳。此外,还对燃烧后吸附室进行了研究,以捕获小型固定发动机排放的二氧化碳。最近,研究人员对以生物质为基础的活性炭作为吸附剂从发动机尾气中捕获二氧化碳进行了研究。捕集装置中使用了三种生物质吸附剂(a)椰壳吸附剂、(b)稻壳吸附剂和(c)桉树木吸附剂来捕集 CI 发动机废气中的二氧化碳。本研究使用的是单缸、四冲程、风冷、自然吸气、直喷(DI)CI 发动机,转速恒定为 1,500 rpm,功率为 4.4 kW。通过将吸附室与在不同负荷下使用柴油(D100)的试验发动机的排气系统相连接,对吸附剂样品的吸附性能进行了研究。使用变温吸附 (TSA) 再生原始吸附剂。通过使用相同的吸附剂进行多次吸附-解吸测试循环来评估吸附剂的吸附能力。在 TSA 过程中,从捕获装置释放出的二氧化碳会被进一步捕获并储存在气袋中。捕获的气体样品通过气相色谱-质谱(GC-MS)表征技术进行表征,以检查和确保吸附剂样品的气体吸附功效。本文详细讨论并介绍了这项研究的成果。© 2023 化学工业协会和 John Wiley & Sons, Ltd. 保留所有权利。
