催化作用与燃烧*技术的结合已有很长的历史,本文通过阿曼、杰诺以及巴士拉三种原油产生油气进行实验。油气与空气混合后进入到催化燃烧装置,在贵金属催化剂的作用下无焰催化燃烧反应,生成CO2和H2O,并测量最后油气出口浓度。实验结果表明,催化燃烧法处理油气效率95%以上,出口浓度为25mg/m3以下,符合国家挥发性有机物排放标准。  相似文献

考察了2种铜锰混合型催化剂低温催化燃烧各种VOCs的反应活性,以及这2种催化剂的抗湿性能和受空速的影响.结果表明,2种催化剂都能在低于260℃完全催化燃烧VOCs;1号催化剂的催化活性和抗湿性能更优.通过BET,XRD.XPS,SEM等表征发现,2种催化剂呈现无定形状态,表面孔分布特别丰富,2种催化剂都有大的比表面积,这些因素就促使2种催化剂对VOCs有高的低温活性.通过XPS分析,Cu2p3/2显示Cu元素主要是 2价,Mn2p3/2显示Mn元素主要是 4价.  相似文献

Recent measurements of wave induced hull strain and flexure in RN warships are presented together with the derivation of the current design criteria for extreme hull girder bending loads. The history of the development of the shipboard instrumentation used is given and recent developments to improve the quality and ease of analysis of the data are described. An unexpectedly high transverse asymmetry in the longitudinal strains measured in destroyers is shown to be the result of a combination of vertical and lateral bending in oblique seas. Finally recent theoretical comparisons between the loading of Deep-Vee hulls and conventional UK rounded bilge hulls are presented which demonstrate the higher loading experienced by this type of hull form.  相似文献

Despite the many socio-economic similarities between Sweden and Norway, differences in jurisdiction, organisation, cooperation, and financing of long-distance passenger train and coach services have led to the development of four distinctively different ways of serving the markets. This paper describes how the train and coach markets have developed in the two countries, with emphasis on regulatory and industrial structure and a couple of performance variables.Looking at passenger rail, both countries separated infrastructure from operation over a decade ago. However, while Norwegian rail is characterised by an almost monopoly supplier, rail services in Sweden are partly decentralised to the responsibility of county authorities and are widely subjected to competitive tendering. The rest of the network is about to be opened up for on-the-track competition. Swedish Rail (SJ) has spent the last decades consolidating its core business (passenger rail) and sold out its other businesses. In contrast, the Norwegian state rail (NSB) has expanded its business to become a major bus operator and property owner, with extensions also into the Swedish market.The coach industry was more recently deregulated in both countries. The Swedish coach market is dominated by privately owned companies operating services to and from Stockholm. In Norway, state-owned NSB is a major coach operator on medium distance routes, and is also the largest partner of Nor-Way Bussekspress which totally dominates long-distance coach services. Further, the Norwegian coach market is characterised by cross-ownership and cooperation which has enabled an extensive route network which covers most of Norway.We find distinct differences in achievements in the two modes and in the two countries. Swedish rail services have succeeded in winning market shares and in renewing and developing both infrastructure and service levels to a greater extent than the Norwegian model. On the other hand, the Norwegian coach market seems to be more developed and efficient compared to its Swedish counterpart.The paper concludes with a discussion on the possible links between the different approaches and the performance observed, with the aim to stimulate further and more detailed research on some important issues.  相似文献

开放式数据挖掘系统模型   总被引:2,自引:0,他引:2  
目前国内已经出现了少量的数据挖掘相关产品。国内数据挖掘软件无论从数量还是质量上比较,都与国外软件存在着较大的差距。随着数据仓库技术的普及,数据挖掘应用的需求越来越强烈,如何缩短这种差距,研发数据挖掘软件产品成为国内业界的一个重要问题。通过引用目前国际通用数据挖掘标准技术来构建开放式的数据挖掘系统模型,该系统模型从可扩展性、可重用性、易用性等方面得到了加强。  相似文献
