Abstract

The mutual solubility and polymerization in the furfural-hydroquinone-urotropin system were studied. Microporous carbon was obtained by activating the carbonized polymer with potassium hydroxide. It has been found that, depending on the mass ratio of KOH to carbonizing polymer, the specific surface area of the activated carbon varies from 2010 to 3307 m/g, and the micropore volume varies from 0.941 to 1.124 cm/g. The surface and porosity parameters of model carbon structures with homogeneous square or hexagonal pores were calculated. It is assumed that the micropore volume of the obtained activated carbons is approaching the theoretical limit. The resulting coals can be used as effective adsorbents.

糠醛-对苯二酚-尿激酶体系中微孔碳的合成
研究了糠醛-对苯二酚-尿促激素体系的溶解度和聚合反应。用氢氧化钾活化碳化聚合物得到微孔碳。研究发现,根据KOH与炭化聚合物的质量比,活性炭的比表面积在2010 ~ 3307 m/g之间变化,微孔体积在0.941 ~ 1.124 cm/g之间变化。计算了具有均匀方孔和六边形孔的模型碳结构的表面和孔隙率参数。假设所得活性炭的微孔体积接近理论极限。所得煤可作为有效的吸附剂。
