~1H和~(13)C NMR研究证明被吸附在不同孔结构活性炭中的烃类以毛细管凝聚和吸附在固体表面两种状态存在。链状烷烃平铺地吸附在固体表面。被吸附烃与活性炭表面酸性基团的质子交换在弛豫过程中起着重要作用。
~ 1H and ~ (13) C NMR studies show that hydrocarbons adsorbed on activated carbons with different pore structures exist in two states: capillary condensation and adsorption on solid surface. Chain alkanes tiled to the surface of the solid adsorption. Proton exchange between the adsorbed hydrocarbon and the acid groups on the surface of the activated carbon plays an important role in the relaxation process.
