| 1 | Studies on Mo/HZSM-5 Complex Catalyst for Methane Aromatization显示文摘The influence of adding Fe, Cr, Co, and Ga into 3%Mo/HZSM-5 catalyst on methane aromatization, and the influence of additives ratio on methane conversion, selectivity to hydrocarbons and coke,as well as distribution of aromatics were investigated. The experimental results showed that the addition of Fe, Cr, Co and Ga promoted the dehydrogenation and dissociation of methane. The results of NH3-TPD indicated that the acidity of HZSM-5 was changed by adding Fe and Co components, consequently the catalytic properties of Mo/HZSM-5 were changed. It was also revealed that strong acid sites were the center of methane aromatization. The results of XRD characterization showed that the crystallinity of Mo on ZSM-5 zeolite was increased after adding Fe, Co additives. | Qun Dong Xiaofei Zhao Jian Wang M.Ichikawa | 2004 | Journal of Natural Gas Chemistry2004，13，1： | 1 |
| 2 | A DEVELOPMENT OF COMPUTER SUPPORT SYSTEM FOR WING DESIGN显示文摘Since it takes a long time to design an aircraft, the succession to or the acquirement of knowledges and technologies is a key to provide to aircraft design high quality and productivity. This paper describes a computer support system for wing design using a new tool based on an object-oriented approach. The system is programmed in a module of objects which represent design tasks or design knowledges. The modulated program gives advantages to maintain and extend the system easily. The system provides to users a flexible support with excellent user interface which consists of mouse, menu-driven system, and window system. | Y.Murotsu C.S.Park M.Ichikawa | 1991 | Chinese Journal of Aeronautics1991，6，2： | 0 |
