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)

大多数工业过程都需要纯净或已在某种程度上纯化的化学物质。大规模蒸馏和过滤等过程是高能量密集型和工业化学纯化的占全球能源消耗的10-15％（Oak Ridge National Lab。分离技术的材料：减少能源和减排机会（2005年）。多孔固体可以将气体分开，可为分子海绵分开，它们可以提供大量的能源节省。该赠款要求一块基础设施，具有测试气体如何通过多孔固体渗透的核心功能，并通过这样做，可以将混合物分开。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及其对固体的亲和力。与请求的设备的重要差异是在竞争中流过固体床时评估竞争中多种气体的能力。确实，这是获得真正的选择性，过程周期时间并最终推断能源成本的所需数据。缺乏这些数据被认为是多孔固体学术研究的缺点（Sholl＆Lively-Nature 2016，532，435）。该技术，启用实验和提取的知识适用于广泛的材料和应用，因此提供了广泛相关的培训。申请人跨越了三个不同的部门（化学，化学工程，地球科学）和计划不同的实验，这反映了受影响的研究和适用培训的广度。大多数能够进行这些研究的设备都是在家中建造的，因为尚未有商业上的版本。这使得在研究小组之间进行比较，具有挑战性。 MicroMeritics首次提供了选择性的吸附分析仪，并且在加拿大尚未安装。因此，仅提供一个供应商。（ATS-Scientific）
