煤基(Co+H_2)合成燃料型混合低碳醇是煤碳化学深加工,以煤代油用于新型汽车燃料的重大课题。本文旨在运用SEM、TEM、u-D、HREM等分析手段,对我所开发特征及结晶学特性上研究与其催化活性中心等的内在关系,为该类催化剂的研制及评价提供依据。从SEM图中可以看到其表面呈多空的疏松结构,并且表面有较多的小颗粒沉积,形成不规则的外形。从TEM图中可以看到大量的微孔结构形成的疏松体,但在某些局部区域可以看到少量致密结构,这表明该催化剂体系从形态上看处于比较多孔的结构,并说明其晶相可能处于较复杂结构,这种表面形态特 Coal-based (Co + H_2) synthetic fuels mixed with lower alcohols are chemical deep processing of coal, with coal instead of oil for a new type of automotive fuel a major issue. The purpose of this paper is to use SEM, TEM, u-D, HREM and other analytical means to study the intrinsic relationship between the characteristics and crystallographic characteristics of my development and its catalytic activity center, and provide the basis for the development and evaluation of this kind of catalyst. From the SEM image, we can see its surface is porous and loose structure, and the surface of more small particles deposited to form an irregular shape. A large number of porous structures with loose bodies can be seen from the TEM image, but a few dense structures can be seen in some of the localized areas, indicating that the catalyst system is morphologically more porous and shows that its crystalline phase May be in a more complex structure, this surface morphology special
