| 摘 要： | 介绍了正交实验法用于煤沥青基活性炭的研制,在固定碱炭比的条件下,分析了炭化温度(A)、炭化时间(B)、活化温度(C)及活化时间(D)四因素对活性炭比表面积的影响。通过直观分析和方差分析可知,四因素中对BET比表面积影响次序为:B>D>A>C,从而找出制备煤沥青基活性炭的最优工艺条件A3B1C1D2,并且在炭化温度为450℃、炭化时间为30min、活化温度为800℃和活化时间为100min的条件下制备出比表面积为1846m2/g的活性炭。

| Abstract: | The orthogonal experiment was applied in the research of coal tar pitch-based active carbon. The influence of carbonization temperature (A), carbonization time (B), activation temperature (C) and activation time (D) on specific surface area under fixed ratio of alkali/carbon was analyzed. It can be known by intuitionistic analysis and variance analysis that B>D>A>C. The optimum technology found out from the orthogonal test data was as follows: A3B1C1D2, and the active carbon with specific surface area of 1 846 m2/g was produced under the conditions of carbonization temperature of 450℃, carbonization time of 30min, activation temperature of 800℃ and activation time of 100min. |
