【摘要】 一系列不同结构的苯乙烯-二乙烯苯共聚物小球,经浓硫酸处理后进行高温裂解,得到球形碳化树脂。测定了碳化树脂的比表面、表观密度、骨架密度、孔隙率和平均孔径等与原始共聚物结构间的关系。研究了某些球形碳化树脂对各种气体的色谱分离效率。实验证明,某些球形碳化树脂对于惰性气体,永久气体和C₁～C₃低碳烃气体具有良好的分离能力。更多还原

【Abstract】 A series of styrene-divinylbenzene copolymer beads of different structures were first sulfonated with concentrated sulphuric acid and then pyrolyzed under nitrogen atmosphere in a cracking furnace. The properties of the carbo -snaceous absorbents were correlatad with the structures of the original copoly-mers such as the surface area, apparent density, skeletal density, porosity, and averege-pore radius, etc. The chromatographic separation efficiency of some spherical carbonaceous adsorbents for various gases were studed. It has been proved that the separation efficiency for inert gases, permanent gases and C1-C3-light hydrocarbons is excellent.更多还原
