U.S.-Korea Cooperative Research on the Effects of Pore Size on Deactivation of Nickel Catalyst

这项提案要求资金允许佛罗里达大学化学工程系的Hong H.Lee博士与韩国高级科学技术研究所(KAIST)反应工程实验室的Sang Heup Moon博士进行为期18个月的研究，关于孔尺寸对苯加氢镍催化剂失活影响的合作研究计划。由于反应的放热性质，这些催化剂同时受到烧结和结焦(中毒)的影响。研究的目的是确定孔大小对失活速率的影响，以便设计出延长加氢反应寿命的镍催化剂。在合作项目中，文在寅将准备并测试不同载体孔径的催化剂。Lee博士将从理论上分析载体孔径大小对这些金属催化剂烧结的影响。由于催化剂同时受烧结和结焦的影响，为了正确分析催化剂效率的数据，还必须确定有多少失活是由于烧结造成的。除了该项目作为基础研究研究的重要性外，这项研究还可能在工业催化中有重要的应用，在工业催化中，催化剂的有效性与烧结程度成反比。合作者是这一研究领域备受尊敬的科学家。本项目将使他们能够将自己的才华和兴趣结合起来，实现互利共赢。该项目与美韩合作科学计划的目标相关，该计划旨在通过交流科学信息、想法、技能和技术以及通过在互利问题上的合作来提高美国和韩国科学家和工程师之间的合作水平。韩国参与该项目得到了韩国科学与工程基金会(KOSEF)的支持。

This proposal requests funds to permit Dr. Hong H. Lee, Department of Chemical Engineering, University of Florida, to pursue with Dr. Sang Heup Moon, Reaction Engineering Laboratory, Korea Advanced Institute of Science and Technology (KAIST), for a period of 18 months, a program of cooperative research on the effects of pore size on deactivation of nickel catalysts for benzene hydrogenation. These catalysts are affected both by sintering and coking (poisoning) due to the exothermic nature of the reaction. The objective of the research is to determine the effects of pore size on the deactivation rate so that a nickel catalyst can be designed for an extended lifetime for the hydrogenation reaction. In the cooperative project, Dr. Moon will prepare and test catalysts of varying support pore size. Dr. Lee will provide a theoretical analysis of the effect of support pore size on the sintering of these metal catalysts. Because the catalyst is affected both by sintering and coking, a determination also must be made as to how much of the deactivation is due to sintering in order to properly analyze data on catalyst effectiveness. In addition to the importance of the project as a basic research study, this research may have important applications in industrial catalysis, where the effectiveness of the catalyst is inversely related to the extent of sintering. The collaborators are highly respected scientists in the field of this research. The present project will allow them to combine their talents and interests for mutual benefit. This project is relevant to the objectives of the U.S.-Korea Cooperative Science Program which seeks to increase the level of cooperation between U.S. and Korean scientists and engineers through the exchange of scientific information, ideas, skills, and techniques and through collaboration on problems of mutual benefit. Korean participation in the project is supported by the Korea Science and Engineering Foundation (KOSEF).
