【摘要】 以ZnCl2为活化剂,采用微波辐射甘蔗渣制备活性炭,研究了微波功率、活化时间、ZnCl2用量与甘蔗渣质量比、干燥功率对活性炭性能的影响。试验的最佳反应条件:ZnCl2与甘蔗渣质量比为2.5:1.0、炭化及活化微波有效功率为35W/g(甘蔗渣,干重)、炭化及活化时间为25min、干燥有效功率为12W/g(活性炭,干重)。在上述条件下制得的活性炭的比表面积为1250㎡/g以上。更多还原

【Abstract】 The feasibility of preparing activated carbon from bagasse with zinc chloride by microwave irradiation was researched.The effect of microwave power,catalyzing time,the rate of zinc chloride to bagasse and drying power were investigated.On the basis of the pilot scale apparatus,the optimum running condition from the lab scale study was discussed.The results indicated that the rate of 2.5:1.0 by weight of zinc chloride to bagasse was suitable,the microwave power of carbonation and catalyzing was 35W/g(bagasse,dry basis),the time of carbonation and catalyzing was 25 minutes,the drying power was 12W/g(activated carbon,dry basis),and finally the specific surface area of activated carbon was over 1250m2/g.更多还原
