Most industrial processes require chemicals that are pure or have been purified to some extent. Processes such as large-scale distillation and filtration are highly energy intensive and industrial chemical purification accounts for 10-15% of the world's energy consumption (Oak Ridge National Lab. Materials for Separation Technologies: Energy and Emission Reduction Opportunities (2005).) Porous solids can separate gases, akin to a molecular sponge and they can offer significant energy savings. This grant requests a piece of infrastructure with the core function of testing how gases permeate through porous solids and by doing so, enable separation of mixtures. There is other infrastructure that measures the amount of a given gas sorbed by a porous solid and its affinity for the solid. A critical and enabling difference with the requested equipment is the ability to assess multiple gases in competition as they flow through a bed of solid. Indeed, this is the needed data to derive true selectivity, process cycle times, and ultimately extrapolate energy costs. Lack of these data is recognized as a shortcoming in academic studies of porous solids (Sholl & Lively-Nature 2016, 532, 435). The technique, enabled experiments and knowledge extracted are applicable to a wide range of materials and applications and hence offers broadly relevant training. The breadth of impacted research and applicable training is reflected by the fact that the applicants span three different departments (Chemistry, Chemical Engineering, Geosciences) and plan diverse experiments. Most equipment able to carry out these studies is home-built as there has not been a commercially available version. This makes comparing data across research groups challenging. Micromeritics offers a selective adsorption analyzer for the first time and no installation yet exists in Canada. As such, only a single vendor is provided.(ATS-Scientific)

大多数工业过程需要纯的或经过一定程度净化的化学物质。大规模蒸馏和过滤等过程是高度能源密集型的，工业化学净化占世界能源消耗的10%-15%(橡树岭国家实验室)。分离技术的材料：能源和减排机会(2005年)。多孔固体可以分离气体，就像分子海绵一样，它们可以显著节省能源。这笔拨款要求一项基础设施，其核心功能是测试气体如何渗透到多孔固体中，并通过这样做，实现混合物的分离。还有其他基础设施可以测量多孔固体吸附的给定气体的量以及它对固体的亲和力。与所需设备的一个关键和使人信服的区别是，当多种气体流经固体床时，能够评估竞争中的多种气体。事实上，这是推导出真正的选择性、工艺周期时间以及最终推断能源成本所需的数据。在多孔固体的学术研究中，缺乏这些数据被认为是一个缺陷(Sholl&Liavy-Nature 2016,532,435)。这项技术、使能的实验和提取的知识适用于广泛的材料和应用，因此提供了广泛的相关培训。受影响的研究和应用培训的广度反映在申请者跨越三个不同的系(化学、化学工程、地球科学)并计划不同的实验。大多数能够进行这些研究的设备都是自制的，因为还没有商业化的版本。这使得对不同研究小组的数据进行比较具有挑战性。Micromeritics首次提供选择性吸附分析仪，加拿大目前还没有安装。因此，只提供一个供应商。(ATS-Science)
