天然气直接转化制乙烯和高值化学品的新途径——中国科学院大连化物所甲烷高效转化相关研究获重大突破

近日,中国科学院大连化学物理研究所包信和研究团队基于“纳米限域催化”的新概念,创造性地构建了硅化物晶格限域的单中心铁催化剂,成功地实现了甲烷在无氧条件下选择活化,一步高效生产乙烯、芳烃和氢气等高值化学品.相关成果发表在2014年5月9日出版的Science344（6184）：616-619]上.同时,相关成果的PCT专利申请已进入美国、俄罗斯、日本、欧洲和中东等国家和地区.

Direct,Catalytic Conversion of Methane to Ethylene and High-value-added Hydrocarbons

Based on the concept they developed, i.e. ＂catal- ysis by nano-confinement＂, Prof. BAO Xinhe＇s group at Dalian Institute of Chemical Physics, Chinese Academy of Sciences, has designed and synthesized a novel cata- lyst with single iron sites confined within the silicide matrix. The lattice-confined iron catalyst enables selec- tive activation of methane under non-oxidative condi- tions, and the direct conversion of methane to ethylene, aromatics, and hydrogen exclusively. The results were reported in the May 9th issue of Science. Meanwhile, patent applications under the patent cooperation treaty have concurrently entered countries and regions inclu- ding USA, Russia, Japan, Europe and Qatar.
