微波-水蒸气法再生载亚甲基蓝废活性炭研究
Study on microwave regeneration and characterization of activated carbon
摘要
Abstract
In the pursuit of enhancing the reuse potential of activated carbon,this paper leverages the favorable microwave heating characteristics and absorptive properties of activated carbon.Corn straw activated carbon was taken as the experimental object,microwave combined with steam method was employed to conduct the regeneration experiment.The regeneration effectiveness is assessed through the methylene blue adsorption value.Both Single-factor experiment and three-factor,three-level orthogonal experiment were set up to scrutinize the effects of microwave power,microwave time and steam flow on biochar regeneration.Additionally,X-ray diffraction characterization is employed for raw carbon,waste carbon,and regenerated activated carbon.The experimental results indicate that the power exerts the most significant influence on the regeneration effect,and the higher power and steam flow correlating to superior regeneration effects.Nonetheless,it is essential to avoid excessive microwave duration.The regeneration rate of activated carbon reaches approximately 75%under the microwave power of 800 W,microwave time of 15 min and steam flow of 5 mL/min.Microwave heating can facilitate the pyrolysis of adsorbent,and steam can clean the carbon pore,so that the activated carbon can recover the original adsorption activity.This method demonstrates notable efficacy,is cost-effective,and holds promise for practical engineering applications.关键词
