Enchanted by the glamour of the fascinating effects resulting from the collisions between the molecules of hydrogen, deuteride and fluorine, Prof. YANG Xueming never expects to attract too many spotlights. However, over the past few years after his returning to the Dalian Institute of Chemical Physics (DICP), CAS, his team was frequently caught by the media on the center stage. Discoveries made by his team ranked top 10 S&T advancements of China consecutively in 2006 and 2007. Significant progress was also made in 2008 by this group in the research field of molecular reaction dynamics, and he himself has won a number of important awards and prizes. 相似文献

<正>With the large reserves of natural gas around the world,such as shale gas,methane hydrate,and biogas,research on how to utilize these alternative fuels has grown considerably.Current industrialscale processes for the conversion of natural gases to useful chemical feedstocks,which involves the conversion to syngas intermediates,are complex,inefficient and costly,and they generate large quantities of CO2 and coke byproducts.The efficient conversion of these natural gas fuels will require a process wherein the C-H bond of methane is activated,and the methane is selectively converted to useful chemical products while minimizing depth dehydrogenation and overoxidation.Many methods have been developed for the activation and conversion of methane with varying degrees of success,but thus far,none has been viable as 相似文献

<正>乙烯、丙烯是极其重要的基本有机化工原料,其传统生产技术强烈地依赖于石油资源。但我国石油资源短缺,原油对外依存度逐年增加,2012年的对外依存度为58%、2013年为58.8%、2014年超过59.5%,如果按照目前的原油消费水平和国内产量的增速来估算,2020年我国原油的对外依存度将超过70%。相应的,我国乙烯、丙烯的产能也严重不足。2013年我国乙烯、丙烯产量分别为1621.8万吨和1626.9万吨,合计产量为3249万吨,而包括聚乙烯和 相似文献
