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.

Akira Tomita教授与Ljubisa R.Radovic教授的研究小组之间的三年合作是由宾夕法尼亚州立大学的Tomita教授的三个月工作的。他的结果帮助我们阐明了碳支持在铜催化NOX减少中的作用。他们还展示了结合瞬时动力学和温度编程的解吸技术在阐明催化和未催化的碳气化机制中的实用性。我们合作的第二阶段是我实验室Hamashita博士的三个月住宿，从6月起，到1992年8月。Yamashita博士使用瞬时动力学和温度编程的解吸技术来研究H2抑制对钙催化的碳气化的影响。我们合作的第三阶段是拉多维奇教授在11月对日本的一周访问1992年。托米塔（Tomita）和京都（Kyotani）教授，我们讨论了我们的联合研究和未来计划的结果。我们合作项目的第四阶段也是最后一个阶段是拉多维奇教授的研究协会Tinghong Tao教授的三个月访问。 Tomita的实验室（1993年9月至11月）。 Tao先生研究了阳离子（例如CA，CU，NA，LA）在Y-沸石中的影响对从Coked液体开裂催化剂中去除碳的动力学。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，这些碳催化剂系统的气化行为被认为类似于常规碳支持的催化剂。我们正在分析和讨论这些结果，而基于这项工作的一些出版物正在准备。
