Production of Crystallized Carbon for Electromagnetic Shielding from Lignocresol by Nickel-Catalyzed Carbonization : Influence of Calcium Co-loading (I)
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.
