项目摘要

The three-year collaboration between the research group of Prof.Akira Tomita and the research group of Prof.Ljubisa R.Radovic was initiated with three months working of Mr.H.Yamada, Prof.Tomita's student, at Pennsylvania State University. His results have helped us to elucidate the role of the carbon support in the copper-catalyzed reduction of NOx. They also showed the usefulness of combining the transient kinetics and temperature-programed desorption techniques in elucidating the mechanisms of catalyzed and uncatalyzed carbon gasification.The second phase of our collaboration was the three-month stay of Dr.Hiromi Yamashita in my laboratory, from June to August 1992. Dr.Yamashita used the transient kinetics and temperature-programed desorption techniques to study the effects of H2 inhibition on the calcium-catalyzed carbon gasification.The third phase of our collaboration was Prof.Radovic's one-week visit to Japan in November 1992. With Profs.Tomita and Kyotani, we discussed the results of our joint research and our future plans.The fourth and final phase of our collaborative project was the three-month visit of Prof.Radovic's research associates, Tinghong Tao, to Prof.Tomita's laboratory (September-November 1993). Mr.Tao studied the effects of cation (e.g., Ca, Cu, Na, La) in Y-zeolites on the kinetics of carbon removal from coked fluid cracking catalysts. He used a number of different techniques (e.g., XPS, EXAFS) to characterize these carbon-catalyst systems, whose gasification behavior is postulated to be analogous to that of conventional carbon-supported catalysts. We are in the process of analyzing and discussing these results, and several publications based on this work are in preparation.

富田明教授的研究小组和柳比萨·R·拉多维奇教授的研究小组之间为期三年的合作是由富田教授的学生山田先生在宾夕法尼亚州立大学工作三个月开始的。他的研究结果帮助我们阐明了碳载体在铜催化还原NOx中的作用。他们还表明，瞬态动力学和程序升温脱附技术相结合，在阐明催化和非催化碳气化的机制，我们的合作的第二阶段是Hiromi Yamashita博士在我的实验室，从1992年6月至8月的三个月的逗留。Yamashita博士使用瞬态动力学和程序升温脱附技术研究了H2抑制对钙催化碳气化的影响。我们合作的第三阶段是Radovic教授于1992年11月对日本进行的为期一周的访问。我们与富田教授和京谷教授讨论了合作研究的结果和未来的计划。我们合作项目的第四阶段也是最后阶段是拉多维奇教授的研究伙伴陶廷宏对富田教授的实验室进行了为期三个月的访问（1993年9月至11月）。陶先生研究了阳离子的影响（例如，Ca，Cu，Na，La）对结焦流化裂化催化剂脱碳动力学的影响。他使用了许多不同的技术（例如，XPS，EXAFS）来表征这些碳催化剂系统，其气化行为被假定为类似于传统的碳负载催化剂。我们正在对这些结果进行分析和讨论，并正在准备基于这项工作的几个出版物。
