This Small Business Innovation Research (SBIR) Phase II project proposes to develop a ceramic nanofiltration membrane with highly uniform pores oriented perpendicularly to the membrane surface using DNA as a template in a silica sol-gel. This membrane will be optimized to perform molecular separation and purification of fuels and chemicals from cellulosic biomass. The research objectives are to create a membrane with the desired pore size and orientation features. A prototype membrane will be produced and tested for its ability to dewater biofuels by pervaporation. It is anticipated that the selective ceramic membrane layer will provide efficient separations and have high temperature and chemical tolerance. The membrane will have applications for a range of industrial markets including wastewater purification and desalination.The broader impact/commercial potential of this project is the development of an innovative membrane technology that will contribute significant energy savings to the production of alternative fuels from cellulosic biomass. Potential end users will include biorefineries that convert cellulosic biomass to fuels and chemicals. A great advantage of molecular separations by membranes rather than distillation is the 40- 50% savings in energy. If successful, this project would lead to a new class of high-throughput ceramic nanofiltration membranes that will have applications to other industrial sectors, including wastewater purification, natural gas purification, and coal gasification. This project promises to contribute significant energy savings to the production of alternative fuels from renewable resources.

该小型企业创新研究 (SBIR) 第二阶段项目建议使用 DNA 作为硅溶胶-凝胶中的模板，开发一种陶瓷纳滤膜，该膜具有垂直于膜表面的高度均匀的孔。 该膜将被优化以对纤维素生物质中的燃料和化学品进行分子分离和纯化。研究目标是制造具有所需孔径和取向特征的膜。 将生产原型膜并测试其通过渗透蒸发对生物燃料进行脱水的能力。 预期选择性陶瓷膜层将提供有效的分离并具有高温和化学耐受性。 该膜将应用于一系列工业市场，包括废水净化和海水淡化。该项目更广泛的影响/商业潜力是开发创新的膜技术，该技术将为利用纤维素生物质生产替代燃料做出显着的节能贡献。 潜在的最终用户将包括将纤维素生物质转化为燃料和化学品的生物精炼厂。 与蒸馏相比，通过膜进行分子分离的一大优点是可以节省 40-50% 的能源。 如果成功，该项目将产生新型高通量陶瓷纳滤膜，并将其应用于其他工业领域，包括废水净化、天然气净化和煤气化。 该项目有望为利用可再生资源生产替代燃料做出显着的节能贡献。
