摘要：以木屑气化剩余炭粉为原料,通过添加活化助剂次氯酸钙和使用黏结剂羧甲基纤维素钠、沥青、酚醛树脂成型,经炭化、水蒸气活化,制得成型活性炭。考察了黏结剂种类和添加量、活化助剂添加量、水蒸气活化条件对制备活性炭性能的影响,结果发现:沥青、酚醛树脂作黏结剂时,单独和配合使用都可以制备性能较好的成型活性炭;活化助剂的添加有利于提高制备活性炭的吸附性能,但会影响活性炭强度和得率。当活化助剂添加0.3 g、水蒸气活化温度850℃、水蒸气活化时间45 min、水蒸气流量1.5 mL/min时,沥青(添加量25 g)为黏结剂制备的活性炭AC1、酚醛树脂(添加量6 g)为黏结剂制备的活性炭AC2、沥青(添加量10 g)和酚醛树脂(添加量3 g)共为黏结剂制备的活性炭AC3,3种样品的碘吸附值最高超过900 mg/g,亚甲基蓝吸附值最大达180 mg/g,强度最高为99%,得率最高为32.9%;活性炭的微孔率最高大于83%,比表面积和总孔容积最大达697.04 m 2/g和0.38 cm 3/g。
Using residual carbon powder from sawdust gasification as raw material,the formed activated carbon was obtained by adding activating agent(calcium hypochlorite),binders(carboxymethyl cellulose sodium,asphalt,phenolic resin),and then carrying out carbonization and water vapor activation process.The properties of activated carbon were influenced by many factors,such as the types of the binders,the adding amount of binders and activation agent,and the conditions of the water vapor activation.The aforementioned factors were investigated amply.It was found that the formed activated carbon with good properties could be prepared by using asphalt and phenolic resin as binder alone or in combination.The addition of activation agent could improve the adsorption performance of activated carbon,but reduce the strength and yield.Adding activating agent(0.3 g),the activated carbons were prepared by water vapor activation(850℃,45 min,1.5 mL/min)via three molding modes:AC1 with asphalt(addition amount 25 g)as binder,and AC2 with phenolic resin(addition amount 6 g)as binder,AC3 with the mixture of asphalt(addition amount 10 g)and phenolic resin(addition amount 3 g)as binder.The maximal iodine adsorption value was over 900 mg/g,the maximal methylene blue adsorption value reached 180 mg/g,the maximal strength was 99%,and the maximal yield was 32.9%.The pore size of activated carbon was mainly microporous,and the maximal micropore content was over 83%.The maximal specific surface area and total pore volume were up to 697.04 m 2/g and 0.38 cm 3/g,respectively.
