摘　　要：针对煤基活性炭性能不佳的问题,以太西煤(TX)和灵武煤(LW)为原料,通过对配煤、炭化、活化等工艺的优化,从而制备一种高性能活性炭,并对制备的活性炭进行孔结构表征和柴油吸附脱硫性能评价。结果表明,该活性炭制备的优化工艺条件为:配煤质量比为89%TX+11%LW、活化剂(KOH)质量分数0.8%、炭化温度600℃、升温速率为10℃/min;活化温度850℃。改进工艺后煤基活性炭的比表面积和微孔面积与椰壳活性炭相近,分别为984.94 m^2/g和713.30 m^2/g;其吸附脱硫性能达到或超过了椰壳活性炭的性能。An innovated high-performance coal-based activated carbon was prepared with using Taixi(TX)and Lingwu(LW)coals as raw materials through optimized blending,carbonization and activation processes.This innovated activated carbon was aimed to overcome the shortcomings of coal-based activated carbon.Furthermore,the micro-pore structure and diesel adsorption desulfurization performance of the prepared activated carbon were also characterized and evaluated,respectively.Experimental results show that the optimized coal blending mass ratio of 89%TX+11%LW,activator(KOH)addition mass fraction of 0.8%,the optimized carbonization temperature,heating rate and activation temperature are 600℃,10℃/min and 850℃,correspondingly.BET characterization results show that the specific surface area and micropore area of the innovated activated carbon(i.e.,984.94 m^2/g and 713.3 m^2/g,respectively)are similar to those of activated carbon from coconut shells.Especially,the absorption desulfurization performance of the prepared activated carbon is similar or better than that of activated carbon from coconut shells.
