研究了镍催化碳化木酚(LC)制备电磁屏蔽(EMS)用结晶碳(T组分)的助剂作用，反应温度为900℃，反应时间为1h。结果表明，对于半焦来说，适宜的镍和钙含量均为8wt%，其T组分的形成和EMS容量均为8wt%；对于其他镍含量，钙镍比为1.0也是最优的。以酸脱盐碱木质素(DAL)为对照，在相同的碳化过程中也观察到类似的情况。这些结果支持之前提出的镍和钙之间的相互作用，并使钙的作用和作用变得清晰。
For effective production of crystallized carbon (T-component) usable for electromagnetic shielding (EMS) from Lignocresol (LC) by nickel-catalyzed carbonization, the promotion effect of calcium co-loaded was investigated in the reaction at 900°C for 1h. It was shown that suitable loadings of nickel and calcium were both 8 wt% for char in terms of the formation of T-component and EMS capacity, and the Ca/Ni ratio of 1.0 was also optimal for other nickel loadings. A similar aspect was observed in the same carbonization of acid-demineralized alkali lignin (DAL) used for comparison. These results supported a previously proposed interaction between nickel and calcium and made the action and role of calcium clear.
