Only H2S consumption and H2O formation was found in the sulfurization of CoMoK/Al2O3 water gas shift catalyst with H2S/H-2. but CO2 was formed first, then CH4, H2O and H2S appeared in the later part of TPS with CS2/H-2. Carbon deposition on the catalyst during the sulfurization with CS2/H-2 caused a lower activity than the catalyst sulfurized with H2S but could be removed in the run of WGS reaction.

随着GPS(全球卫星定位系统)技术的成熟与发展,利用GPS技术进行车辆定位正地被广泛地应用。例如金融系统(运钞车)、公安部门(110报警车)、消防部门(119消防车)、急救中心(120救护车)等。但是,利用GPS进行车辆定位跟踪的传统方法是采用差分GPS技术。该技术的实现需要大量的资金投入,不适于我国目前的经济状况。寻求一种投资少并能实现基本功能的算法从工程角度讲,具有十分现实的意义。本文以“沈阳市消防通讯作战指挥系统”为背景,以单台GPS接收机动态定位模式为实现条件,对车辆定位的实现进行了详细的讨论。首先,建成立了WGS-84坐标系到BJ-54坐标系之间的坐标转换模型,其次,提出了一种基于类投影的地图匹配算法,最后基于该算法进行了实际车辆定位实验。从实验结果看,该算法基本实现了车辆定位的功能。
