Abstract

Solid-state NMR spectroscopy is used to study the proton transfer from aqueous sulfuric-acid solution to coal of early metamorphic stages and to SKN-2K porous carbon sorbent (the carbonized copolymer of 2-methyl-5-vinylpyridine and divinylbenzene). The proton transfer to a spherical polymer granule or a coal membrane is determined by electrolyte diffusion in the solid. In SKN-2K porous sorbent, the diffusion coefficient of sulfuric acid is 1 × 10^–8 m²/s. When the electrolyte flux is perpendicular to the membrane plane, the diffusion coefficient of sulfuric acid is 1 × 10^–13 m²/s.

煤变质早期和SKN-2K碳吸附剂中的质子转移

摘要

固态核磁共振光谱用于研究从硫酸水溶液到早期变质阶段煤和 SKN-2K 多孔碳吸附剂（2-甲基-5-乙烯基吡啶和二乙烯基苯的碳化共聚物）的质子转移。质子转移到球形聚合物颗粒或煤膜是由固体中的电解质扩散决定的。在SKN-2K多孔吸附剂中，硫酸的扩散系数为1×10 ^–8 m ² /s。当电解液通量垂直于膜平面时，硫酸的扩散系数为1×10 ^–13 m ² /s。
