采用山东气肥煤和河南贫煤为主要原料,配入少量太西无烟煤,采用无焦油黏结剂新方法制备柱状活性炭。以苯酚值、碘值、亚甲基蓝值、比表面积、孔径分布和强度等指标表征样品性能。采用正交试验法设计实验方案,研究了原料配比、炭化温度、炭化升温速率、活化温度、活化时间等因素的影响,得到了最佳制备条件。 Adopting Shandong fat coal and Henan lean coal as the main raw materials, with a small amount of Taixi anthracite, columnar activated carbon was prepared by a new method without tar binders. The properties of samples were characterized by phenol value, iodine value, methylene blue value, specific surface area, pore size distribution and strength. The orthogonal design was used to design the experimental scheme. The effects of the raw material ratio, carbonization temperature, carbonization heating rate, activation temperature, activation time and other factors were studied. The optimum preparation conditions were obtained.
