添加剂作用下用粘结性烟煤制活性炭

添加氧化性化学物质用于粘结性结性烟煤制备活性炭，在该添加剂在糖蜜的协同作用下，炭化时可以抑制烟煤的软化、熔融、炭化料没有起泡和膨胀发生，外观光滑整齐，活性炭的碘值最高可达１０４７mg/g，经酸洗后活性炭的灰分可以得到显著的降低，最高降幅为５５．３６％，一般为５０％左右，而不经添加剂处理的活性炭酸洗脱灰率最高仅为３５．１２％，一般在３０％左右。

RESEARCH ON ACTIVATED CARBON FROM CAKING COAL IN THE PRESENCE OF ADDITIVE

Oxidant additive was used in preparation of activated carbon from caking coal. Under the cooperating effects of the additive and molasses, the softening and melting of the ca king coal was restrained during carbonization. No swelling happened to the carbonized material and the outlook was smooth. The resultant activated carbon got a high iodine number. The carbon was deashed markedly by acid washing. The highest deashing rate was up to 55 36% and the highest deashing rate for the carbon non treated with additive is only 35 12%.
