Improvement of the polishing unit for the recovery of base oil**

MemPore Corp.成立于2005年，目的是开发一种系统，将污油提炼成清洁、可重复使用的基础油，并准备建立将用过的润滑油转化为有价值的清洁基础油的系统--10升旧油产生7升清洁基础油。第一次，废油可以从本地系统中以最小的污染进行净化，使用低能源，以低资本和运营成本。MemPore的系统由三个自动化模块组成--前处理(取出水、燃料和乙二醇)；膜(类似于海水的反渗透)；以及最终的再生抛光。MemPore希望开发一种抛光装置，该装置将集成到其膜系统中，用于清洗用过的油。拟议的创新主要集中在为MemPore的废油抛光(吸附)装置筛选各种吸附剂并对其进行方法学表征。抛光单元的进料是膜单元的渗透流，而抛光单元的下游是实际的基础油和最终产品。该研究和开发项目的主要目标是为MemPore的抛光单元收集和生产各种吸附剂的必要特性数据。这些数据有助于MemPore改进和优化其油脂抛光单元中的吸附柱。基本数据是吸附剂的吸附等温线，以及从MemPore抛光装置的进料流中去除重金属和耐磨组分的最大平衡吸附量。根据初步的文献回顾和MemPore的技术诀窍，建议从天然富勒土和活化富勒土、天然膨润土和活化膨润土、硅酸铝13X沸石和铝土矿开始。对吸附材料的研究将从详尽的文献和专利审查以及实验设计(DOE)开始，以实验预筛选吸附剂的分离性能。第二阶段是进行实际的吸附测试，以生成吸附动力学和平衡等温线。未经处理和处理的样品将首先进行研究，以确定达到热力学平衡的时间。然后用它们来测定几种不同温度下的平衡吸附容量。**

MemPore Corp. was founded in 2005 to develop a system that would refine dirty oil into clean, re-usable base oil and is ready to build systems that transform used lubricating oil into valuable clean base oil - 10 liters of used oil yields 7 liters of clean base oil. For the first time, used oil can be purified with minimal pollution, from localized systems, using low energy, and at low capital and operating cost. MemPore's System consists of three automated modules - pre-treatment (to take out water, fuel & glycol); membranes (similar to reverse osmosis of sea water); and final regenerative polishing. MemPore wants to develop a polishing unit that will integrate into its membrane system for cleaning used oil. The proposed innovation is mainly focused on screening various adsorbents and methodologically characterizing them for MemPore's used oil polishing (adsorption) unit. The feed for the polishing unit is the membrane unit's permeate stream while the polishing unit's downstream is the actual base oil and final product. The primary goal of this research and development project is gathering and producing the necessary characteristic data of various adsorbents for MemPore's polishing unit. This data helps MemPore to enhance and optimize the adsorption column in their oil polishing unit. The essential data are the adsorption isotherms of the adsorbents, and the maximum equilibrium capacity of adsorbents for removal of heavy metals and wear components from the feed stream of MemPore's polishing unit. From the preliminary literature review and MemPore's know-how, natural and activated fuller's earth, natural and activated bentonite, aluminosilicate zeolite 13X and bauxite are recommended to begin with. The research on adsorbent materials will start with conducting exhaustive literature and patent review as well as the design of experiments (DOE) for experimentally prescreening the separation performance of adsorbents. The second phase is performing the actual adsorption tests for generating the adsorption kinetics and equilibrium isotherms. The untreated and treated samples will be first studied to determine the time to come to thermodynamic equilibrium. Then they will be used to determine the equilibrium adsorption capacities at several different temperatures. **
