PROPOSAL NUMBER: 0730465PRINCIPAL INVESTIGATOR: Jerry LinINSTITUTION: Arizona State UniversityPROPOSAL TITLE: GOALI: Separation of Oil and Other Organics from Water Using Inverse Fluidization of Hydrophobic AerogelsIn this project the PIs will study a continuously operating inverse fluidized bed of low density,hydrophobic aerogels to remove immiscible (such as oil), partially miscible (such as chlorinatedhydrocarbons), or totally miscible (such as ethanol) organics. The PIs plan to prove that this new sorption process can outperform a packed bed of activated carbon or other conventional sorbents for removing these contaminants. Working in partnership with Cabot Corporation, the PIs also plan to scale up the process and explore commercialization possibilities. To achieve these objectives, the PI will conduct experiments to study the equilibrium and kinetics of sorption of a variety of organic contaminants in water by nanogels of different composition, properties, and size ranges. These results will be used in designing and conducting inverse fluidization experiments, which will concentrate on measuring the hydrodynamics, liquid and particle mixing, and the adsorption/absorption efficiency and capacity of the nanogels. At the same time the PIs will develop physically reliable models to describe the effects of various operating parameters, and to predict the pressure drop, bed porosity, liquid phase mixing, nanogel feed rate and saturation values (capacity). The experimental and modeling results will be used for designing and building a prototype commercial system for treating wastewater, storm water runoff and fermentation broths at Cabot's Billerica R&D Center. Equilibrium and kinetic experiments will be performed to gain an understanding of the sorption mechanisms in hydrophobic nanogels and obtain basic equilibrium and kinetic data needed for modeling the inverse fluidized bed process for continuous separation of organics from immiscible suspensions and aqueous solutions. Broader Impacts: Undergraduate and graduate students working on the research will receive broad education and training in particle technology, nanotechnology, separation processes, and environmental science. They will also have the additional advantage of quickly gaining an industrial perspective by being jointly supervised by the Cabot Co-PIs, and will have the opportunity to spend one or two summers at the Cabot R&D facility in Billerica, MA, working with Cabot engineers to build a prototype system. Each of the four Co-PIs will serve as guest lecturers in appropriate ASU undergraduate or graduate courses, where they will present different aspects of the research to ASU students in the classroom. The University Co-PIs will strive to target the large ASU undergraduate minority and woman talent pool to join the project as research students. The Industry Co-PIs will be responsible for the transfer of new knowledge between ASU and Cabot, as well as exploring marketing and commercialization opportunities.One of the most challenging environmental problems today is the removal of oil and other organic contaminants from industrial wastewater and storm water; the proposed research program has the potential to evolve into a major enabling technology for dealing with this problem. The project will also increase industry's awareness of the opportunities that exist for using nanostructured particles in unique applications and will contribute to US manufacturing competitiveness and the preservation of the environment.

提案编号：0730465 Principal研究者：Jerry LininInstitution：亚利桑那州立大学港口职位：守门员：使用疏水气凝胶的逆流化，将石油和其他有机物与水与水与水分离，PIS将研究一个项目，PIS将研究一个连续运行的低密度，水密度，疏水油的逆流动性床，例如，诸如降低了液化的机油，例如，诸如易于降解的机油（例如），例如）氯化氢碳），或完全混乱（例如乙醇）有机物。 PIS计划证明，这种新的吸附过程可以胜过活性碳或其他常规吸附剂的填充床，以消除这些污染物。 与卡博特公司合作，PIS还计划扩大流程并探索商业化的可能性。 为了实现这些目标，PI将进行实验，以研究通过不同组成，性质和大小范围的纳米凝胶在水中各种有机污染物吸附的平衡和动力学。这些结果将用于设计和进行反流化实验，该实验将集中于测量流体动力学，液体和颗粒混合以及纳米凝胶的吸附/吸收效率和能力。同时，PI将开发物理上可靠的模型来描述各种工作参数的效果，并预测压降，床孔隙率，液相混合，纳米凝胶的进料速率和饱和值（容量）。实验和建模结果将用于设计和构建一种原型商业系统，用于在Cabot的Billerica R＆D中心处理废水，雨水径流和发酵汤。 将进行平衡和动力学实验，以了解疏水性纳米凝胶中的吸附机制，并获得建模逆流动床过程所需的基本平衡和动力学数据，以连续将有机物从不可或缺的悬浮液和水溶液中分离出来。更广泛的影响：研究研究的本科生和研究生将接受粒子技术，纳米技术，分离过程和环境科学方面的广泛教育和培训。他们还将通过由Cabot Co-Pis共同监督来快速获得工业视角的其他优势，并有机会在马萨诸塞州比勒里卡的Cabot R＆D设施中度过一个或两个夏天，并与Cabot工程师合作建立了原型系统。 这四个共同案例中的每一个都将担任适当的ASU本科或研究生课程的客座讲师，在那里他们将向课堂上的ASU学生介绍研究的各个方面。大学的副派将努力以研究学生的身份以大型ASU本科少数民族和女性人才库为目标。该行业的共同党派将负责在ASU和Cabot之间转移新知识，并探索营销和商业化机会。当今最具挑战性的环境问题之一是从工业废水和雨水中清除石油和其他有机污染物；拟议的研究计划有可能发展成为解决此问题的主要促成技术。该项目还将提高行业对在独特应用中使用纳米结构颗粒的机会的认识，并将有助于美国的制造竞争力和环境维护。
