Synthesis gas production on glass cloth catalysts modified by Ni and Co oxides

The catalytic activity of nanostructured low percent (1%) Co-Ni catalysts on the basis of glass fiber (GF) prepared by a"solution combustion" (SC) method was studied.The catalytic activity of the prepared samples was studied in the reaction of dry reforming of methane (DRM) with CO2.The obtained samples were characterized by a number of physico-chemical methods,including XRD,SEM,TEM,TGA and AFM.The active component was shown to be dispersed in the near-surface layer of the support as nanoparticles of 10—20 nm in size.The active component showed a Co3O4 or(Co,Ni)Co2O4 spinel structure,depending on the catalyst composition.The spinel structure of the active component interacted strongly with the carrier,providing resistance to carbonization,high catalytic activity toward DRM,and high activity and stability in oxidation reactions.

俄罗斯圣彼德堡城市环境地图集

当前,大城市和都市聚集现象引起的环境问题致关重要。这些问题是管理部门和环境保护者共同关注的目标,因而具有经济上和政治上的双重意义。有关生态信息的客观性问题正在受到重视。信息可以用不同的方式来解释,对于相同的事件而言,一方面可以被认为是一种灾害,而另一方面又可以被认为是公众的财富。显然,地理信息系统(GIS)技术能够为用户方便、准确地概括和归纳各种环境数据,并提供客观的评价。它是专业环境学家不可缺少的工具。但是还有另外一批环境信息的使用者,他们并不需要使用如此功能强大的工具,而是需要使用一些比较简单的图形资料。这些使用者是普通公众,在俄罗斯的情况下还包括城市或地方的管理部门。我们认为。
