Selective Adsorption Analyzer

大多数工业过程都需要纯的或经过某种程度净化的化学品。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）。分离技术材料：能源和减排机会（2005）。多孔固体可以分离气体，类似于分子海绵，它们可以显著节省能源。这笔拨款要求建设一个基础设施，其核心功能是测试气体如何渗透多孔固体，并通过测试来分离混合物。还有其他基础设施可以测量给定气体被多孔固体吸收的量及其对固体的亲和力。与所要求的设备相比，关键的区别在于能够在多种气体流过固体床时对其进行竞争评估。事实上，这是获得真正的选择性、工艺周期时间和最终推断能源成本所需的数据。缺乏这些数据被认为是多孔固体学术研究的一个缺点（Sholl & Lively-Nature 2016, 532, 435）。所提取的技术、实验和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。申请者跨越三个不同的系（化学、化学工程、地球科学），并计划进行不同的实验，这反映了受影响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自制的，因为还没有商用版本。这使得跨研究小组的数据比较具有挑战性。Micromeritics首次提供选择性吸附分析仪，在加拿大尚未安装。因此，只提供了一个供应商。(ATS-Scientific)

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)
