The textural characteristics of carbon sorbents produced by heating G (gas) coal in the presence of potassium hydroxide (KOH/coal = 0.5 g/g) are studied. In chemical activation with alkali, sorbents with developed specific surface and specific pore volume are obtained; the contribution of micropores is 69–82%. The ash content of the coal has the main influence on the textural characteristics of the sorbents. The specific surface and pore volume of the sorbents are greatest for coal with <10% ash.

煤的灰分含量对生产的碳吸附剂孔结构的影响

研究了在氢氧化钾（KOH/煤 = 0.5 g/g）存在下加热 G（气）煤生产的碳吸附剂的结构特征。在碱化学活化中，得到具有发达的比表面积和比孔容的吸附剂；微孔的贡献为 69-82%。煤的灰分含量对吸附剂的结构特性有主要影响。对于灰分 <10% 的煤，吸附剂的比表面积和孔体积最大。
