以碳酸钙(CaCO_3)、针铁矿[α-FeO(OH)]和苯酚树脂为原料制备了钙碳(Ca-C)和铁-钙-碳(Fe-Ca-C)复合材料。他们被检查了对氯环己烷(CCH)的脱氯。详细研究了钙、铁的最佳配比、有效脱氯的碳化温度。CCH转化率随炭化温度(773-1073K)和Fe/Ca摩尔比的升高而增加。CCH反应速率研究表明，总反应速率与CCH浓度呈一级反应关系。
Calcium–carbon (Ca–C) and iron–calcium–carbon composites (Fe–Ca–C) were prepared from calcium carbonate (CaCO3), goethite [α-FeO(OH)] and phenol resin. They were examined for the dechlorination of a chlorocyclohexane (CCH). The optimum compositions of calcium and iron, the carbonization temperatures for the effective dechlorination were studied in detail. The CCH conversions were found to increase with the elevation of carbonization temperature (773–1073K) and Fe/Ca molar ratio. The CCH reaction rate studies shows that overall reaction rate is first order with the concentration of CCH.
