In the past few decades, research activity has focused on new advanced desiccant and catalyst technology for use in food products, nutritional supplements, packaging (e.g., pharmaceuticals & electronics), ventilation and drying systems, solvent purification, and gas separation. These technologies rely on gas/vapor adsorption, which is a surface phenomenon by which gas/vapor molecules adhere to a surface. Adsorption (accumulation) and desorption (removal) are the focus of this RTI grant; thus, “sorption” will refer to adsorption and desorption, but not absorption, which is a bulk process by which a fluid enters into (or is dissolved by) a liquid or solid. The field of adsorption science and technology has witnessed increasing attention on the synthesis of enhanced sorbents/desiccants and the development of advanced desiccant-based technologies. The 5 RTI applicants at the University of Saskatchewan carry out pioneering research on the development of advanced sorbents/desiccants with emerging applications in energy exchangers, dehumidification systems, CO2 capture and storage, Hydrogen storage, and gas separation technologies. Over the past 6 years, the applicants have published over 300 journal papers, delivered over 300 presentations (~30% invited), supervised over 200 HQP and submitted 18 patents. Recognitions include more than 10 major national/international awards and fellowships and editorial roles on 7 international journals. High precision measurement of the adsorption capacity and kinetics in desiccant materials is essential for the applicants’ fundamental adsorption research and practical Engineering applications. This RTI application is to purchase a high precision gas/vapor adsorption instrument, BELSORP-max II, to support the interdisciplinary research programs in Chemistry and Engineering. The instrument enables the applicants to investigate the sorption of various gases and non-corrosive vapors at a practical range of temperature (5∼70°C) which is not feasible with the available facilities across the campus and throughout Saskatchewan. In total, 5 research programs and about 50 HQP will use the device to fulfil their research objectives within the next 6 years, while several collaborators (academic and industrial partners) will also benefit from the requested device. Availability of the requested device has significant impact on the applicants’ research programs and HQP training. The device will be used by HQP in research and graduate courses. HQP will gain hands-on experience in porous material characterization and sorption analysis. This training will prepare HQP for careers that make contributions in the global adsorbent and catalyst markets (valued at over $20 billion (USD) and expected to grow significantly over the next 5 years due material development, expanded environmental regulations and improved living conditions around the world).

在过去的几十年里，研究活动主要集中在食品、营养补充剂、包装（例如药品和电子产品）、通风和干燥系统、溶剂净化和气体分离中使用的新型先进干燥剂和催化剂技术。气体/蒸气吸附，这是一种表面现象，气体/蒸气分子粘附在表面上，吸附（积聚）和解吸（去除）是本 RTI 资助的重点，因此，“吸附”将指代；吸附和解吸，但不是吸收，吸收是流体进入（或溶解）液体或固体的整体过程。 吸附科学技术领域越来越关注增强型吸附剂/干燥剂的合成和先进干燥剂技术的开发。萨斯喀彻温大学的 5 名 RTI 申请人对先进吸附剂/干燥剂的开发进行了开创性研究。随着能源交换、除湿系统、二氧化碳捕获和储存、氢气储存和气体分离技术等​​领域的新兴应用，申请人在过去 6 年里发表了 300 多种期刊。发表了 300 多篇论文，发表了 300 多篇演讲（约 30% 受邀），指导了 200 多个 HQP，并提交了 18 项专利。获得的荣誉包括 10 多个主要国家/国际奖项和奖学金以及在 7 种国际期刊上担任编辑。 干燥剂材料吸附能力和动力学的高精度测量对于申请人的基础吸附研究和实际工程应用至关重要。本次RTI申请是购买高精度气体/蒸气吸附仪器BELSORP-max II，以支持跨学科研究。该仪器使申请人能够在实际温度范围（5–70°C）下研究各种气体和非腐蚀性蒸气的吸附，这在现有设施中是不可行的。整个校园和整个萨斯喀彻温省。 总共有 5 个研究项目和大约 50 个 HQP 将在未来 6 年内使用该设备来实现其研究目标，而一些合作者（学术和工业合作伙伴）也将从所请求的设备中受益。所请求设备的可用性具有重大影响。 HQP 将在研究项目和 HQP 培训中使用该设备，HQP 将获得多孔材料表征和吸附分析方面的实践经验。表彰为全球吸附剂和催化剂市场做出贡献的职业（价值超过 200 亿美元，由于材料的发展、环境法规的扩大和世界各地生活条件的改善，预计在未来 5 年内将大幅增长）。
