%X 利用管式炉对内蒙古褐煤进行了活性焦制备工艺研究,研究了活化时间、活化温度以及蒸汽量对活性焦吸附性能的影响,并以某厂焦化废水为对象进行吸附试验。结果表明活化温度为850℃,活化时间为90 min,蒸汽通入量为450 g/h条件下制得的活性焦对焦化废水的吸附性能较好。 Introduce the preparation technique of activated char from Inner Mongolia lignite with pipe furnace.Study the influence of time and temperature of carbonization and activation and steam quantity on activated char adsorbability.At last,the adsorption capacity of activated carbon was tested by using coking wastewater from certain coking-plant in Henan Province.The results show that steam quantity 450 g/h,activation temperature 850 ℃,activation time 90 minutes,steam quantity 450 g/h,the activated carbon works best
