This proposal is requesting funding for a semi-pilot scale adsorption setup for the evaluation of solid sorbents performance in gas separation applications with a special focus on CO2 capture. The requested equipment will support the research activities of the principal applicant and three co-applicants working in the field of post-combustion CO2 capture, direct air CO2 capture (DAC), and natural gas purification (H2S and CH4 separation). Existing laboratory equipment used to evaluate solid sorbents performance is based on volumetric and gravimetric techniques using few milligrams to evaluate the gas separation thermodynamics (adsorption isotherms) and kinetics. Process modeling techniques are deployed using single-component adsorption isotherms, kinetics data, selectivity, and heat of adsorption to predict the performance of solid sorbents in large-scale process conditions. However, as valuable as these performance indicators are, they do not accurately predict the cost of the gas separation process, energy requirements, nor the purity and recovery of the separated gas stream. The requested equipment is designed to operate under temperature swing adsorption (TSA) and pressure-vacuum swing adsorption (PVSA) conditions to mimic the real scale cyclic adsorption process and evaluate the performance of solid sorbents under real conditions. The availability of such facilities will help bridge the gap between laboratory-scale materials evaluation methods and the large-scale cyclic adsorption processes. It will also offer a great validation tool for process modeling efforts to accurately predict the performance of solid sorbents for gas separation applications. The requested adsorption setup will be connected to an existing Mass Spectrometer (MS) in our laboratory to enable the online measurement of gas composition at the exit of the adsorption set up to quantify the purity and recovery percent. The requested instrument is essential to support the research programs of 4 applicants, including 1 Industrial Research Chair (IRC) in CO2 Capture Technologies, 2 NSERC-Alliance, 3 NSERC-DG, and 2 Mitacs projects. The research programs supported by the requested equipment are centered on the advanced training and education of Highly Qualified Personnel, HQPs (16 PhD students, 5 MSc students, 2 postdocs, and 2 research assistants). The semi-pilot scale adsorption setup offers a broader training opportunity compared to the small-scale laboratory equipment as the effectiveness, and the quality of data is greatly improved. The gained knowledge will be crucial to making a breakthrough and major advances in developing viable GHG reduction technologies. It is anticipated that the innovative knowledge and novel materials generated from the utilization of this setup will be readily transferable for commercialization, thereby facilitating environmentally friendly energy production.

该提案要求资助一个半中试规模的吸附装置，以评估气体分离应用中固体吸附剂的性能，特别关注二氧化碳捕获。所要求的设备将支持主申请人和三名共同申请人在燃烧后二氧化碳捕获、直接空气二氧化碳捕获（DAC）和天然气净化（H2S和CH4分离）领域的研究活动。现有用于评估固体吸附剂性能的实验室设备是基于体积和重量技术，使用几毫克来评估气体分离热力学（吸附等温线）和动力学。过程建模技术使用单组分吸附等温线、动力学数据、选择性和吸附热来预测大规模工艺条件下固体吸附剂的性能。然而，尽管这些性能指标很有价值，但它们并不能准确预测气体分离过程的成本、能源需求，也不能准确预测分离气流的纯度和回收率。所要求的设备设计在变温吸附（TSA）和变压真空吸附（PVSA）条件下运行，模拟真实的循环吸附过程，并评估固体吸附剂在真实条件下的性能。这些设施的可用性将有助于弥合实验室规模的材料评估方法和大规模循环吸附过程之间的差距。它还将为过程建模工作提供一个很好的验证工具，以准确预测气体分离应用中固体吸附剂的性能。所要求的吸附装置将连接到我们实验室现有的质谱仪（MS），以便在线测量吸附装置出口的气体成分，以量化纯度和回收率。所要求的仪器对于支持4个申请人的研究计划至关重要，包括1个二氧化碳捕获技术工业研究主席（IRC）， 2个NSERC-Alliance， 3个NSERC-DG和2个Mitacs项目。申请设备支持的研究项目以高素质人才（HQPs）的高级培训和教育为中心（16名博士研究生，5名硕士研究生，2名博士后，2名研究助理）。与小型实验室设备相比，半中试规模吸附装置提供了更广泛的培训机会，其有效性和数据质量大大提高。所获得的知识对于在开发可行的温室气体减排技术方面取得突破和重大进展至关重要。预期利用这一装置所产生的创新知识和新材料将很容易转让用于商业化，从而促进无害环境的能源生产。
