       应实验室主任郭烈锦院士邀请,美国德克萨斯大学奥斯汀分校和余桂华(Guihua Yu)教授以及大连理工大学代表团将于7月1日-3日来实验室交流访问,开展双边国际合作研讨,期间为实验室师生做系列精彩学术报告,请实验室相关方向师生积极准备参加会议交流。

 

       报告一:气体分离膜和荷电膜的研制与应用

       报告人:大连理工大学 贺高红 教授

       报告地点:北二楼11楼会议室

       报告时间:2018年7月3日(周二)8:10-9:10

       报告摘要:

       有机非多孔膜的膜材料以分子状态排列,物质以分子或离子的形式透过膜,分离效率高,气体分离膜和荷电膜都是典型的有机非多孔膜,在能源、环境保护及节能减排等领域具有广泛的应用,如气体分离、VOCs回收减排、燃料电池和储能液流电池和等。

       有机非多孔膜性能的关键是材料的分子结构,侧链与透过物质的相互作用,决定了本征的透过性和选择性,主链的稳定性决定寿命,我们设计侧链功能基团促进气体的溶解和离子的迁移,以及膜的微相分离等,提高膜的气体分离性能和荷电膜的导电性和耐溶胀性等;我们选择主链增加耐溶胀能力、改变堆积密度增加机械强度等;膜的最终性能取决于制备工艺,从分子层面设计铸膜液相分离和界面润湿,优化制备工艺。

       气体膜分离在石油化工、环境保护等领域的应用越来越广泛,处理对象也由单一原料、单一回收目标的拟二元简单体系发展至多源头、多目标回收、多用途综合利用的复杂系统。这对膜分离为核心的流程提出了更高的要求。围绕多源化工气体的膜分离资源化和尾气达标排放,建立了多源组分非理想膜过程的快捷、准确模拟,新型耦合多技术整体协同设计,在耦合协同资源化和VOCs减排等领域展开了系统研究,并取得了系列研究成果和工程应用。如通过膜与变压吸附耦合工艺,实现了高纯度、高收率回收炼厂气中的氢气。研发的具有自主知识产权的工艺包,成功用于中石油大连石化80000Nm3/h多源富氢气体中氢气和轻烃的综合处理,是目前国内规模最大的炼厂气综合回收利用装置,经济效益近2亿元/年;开发以膜为核心,结合冷凝和吸附等分离单元优势的循环级联工艺设计方法和具有自主知识产权的系列工艺包;该技术通过协同强化,较美、德等同类技术节能10~40 %,聚烯烃单耗降低0.3~1.0 %,已经占有90 %以上国内烯烃回收市场,并多次在国际、国内竞争中击败美国 MTR和德国BORSIG,并批量出口到日本等国外高端化工市场。

 

       报告二:A Soft Material Approach towards Grand Energy Challenges-An Emerging Class of Functional Polymers

       报告人:美国德克萨斯大学奥斯汀分校 余桂华(Guihua Yu ) 教授

       报告地点:北二楼11楼会议室

       报告时间:2018年7月3日(周二)9:10-10:10

       报告摘要:

       Nanostructured materials have become critically important in many areas of technology, ranging from renewable energy, electronics, photonics, to biology and medicine, because of their unusual physical/chemical properties due to confined dimensions of such materials. This talk will present a new class of polymeric materials we developed recently: nanostructured functional polymer gels that are hierarchically porous, and structurally tunable in terms of size, shape, composition, hierarchical porosity, and chemical interfaces. These organic gels as functional organic building blocks offer an array of advantageous features such as intrinsic 3D nanostructured conducting framework, exceptional electrical conductivity and electrochemical activity to store and transport ions, synthetically tunable structures and chemical interfaces, and they have been demonstrated powerful for a number of significant applications in energy and environmental technologies. Several latest examples on functional organic gels-enabled advanced technological applications such as high-energy lithium batteries, thermoresponsive safe electrolytes, solar steam generation and water desalination, and atmospheric water harvesting, will be discussed to illustrate ‘structure-derived multifunctionality’ of this special class of materials.
