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.

该提案要求为半杆量表吸附设置提供资金，以评估气体分离应用中的固体吸附性能，并特别关注CO2捕获。请求的设备将支持主要申请人的研究活动和三名在燃烧后CO2捕获，直接空气CO2捕获（DAC）和天然气净化（H2S和CH4分离）领域工作的共同申请人。用于评估固体吸附剂性能的现有实验室设备是基于使用少量毫克的体积和重量法技术来评估气体分离热力学（吸附等温度）和动力学的。过程建模技术是使用单组分吸附等温线，动力学数据，选择性和吸附热来部署的，以预测在大规模过程条件下实心吸附剂的性能。但是，像这些性能指标一样有价值，它们无法准确预测气体分离过程的成本，能量需求，也不能准确预测分离的气流的纯度和恢复。 请求的设备旨在在温度摆动吸附（TSA）和压力效率摆动吸附（PVSA）条件下进行操作，以模仿实际规模的循环吸附过程，并评估在现实条件下实心吸附剂的性能。此类设施的可用性将有助于弥合实验室规模的材料评估方法与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的固体吸附剂的性能。所需的吸附设置将连接到我们实验室中现有的质谱仪（MS），以实现在设置的吸附量出口处对气体组成的在线测量，以量化纯度和恢复百分比。请求的工具对于支持4位申请人的研究计划至关重要，其中包括1名工业研究主席（IRC），二氧化碳捕获技术，2个NSERC-Alliance，3个NSERC-DG和2个MITACS项目。所请求的设备支持的研究计划集中在高素质人员，HQP（16名博士生，5名MSC学生，2名PostDocs和2名研究助理）的高级培训和教育上。与小规模的实验室设备相比，半杆量表的吸附设置为有效性提供了更广泛的培训机会，并且数据质量得到了极大的提高。 获得的知识对于在开发可行的温室减少技术方面取得突破和重大进步至关重要。可以预料，该设置的利用产生的创新知识和新颖材料将很容易转移用于商业化，从而促进了环保能源的生产。
