摘　　要：以玉米秸秆为原料,采用限氧慢速热解法制备生物炭,将生物炭用于柴油吸附脱硫。利用X射线衍射(XRD)、扫描电子显微镜(SEM)、热重分析(TG)、傅里叶变换红外光谱(FT-IR)等手段对生物炭进行表征分析,探究炭化温度(200~700℃)和炭化时间(2~8 h)对生物炭的理化性质及脱硫性能的影响。结果表明,炭化时间为8 h,炭化温度为500℃,生物炭骨架结构基本完整、孔隙结构发育好、吸附性能较好,脱硫率为26.9%。Biochars were prepared by limiting oxygen slow pyrolysis method using corn straw as raw materials,and biochars were used for adsorption desulfurization of diesel oil. Biochars were characterized by XRD,SEM,TG,FT-IR,the effects of pyrolysis temperature(200-700 ℃)and residence time(2 to 8 h),respectively,on the physicochemical properties and desulfurization performance of biochars were investigated. The results show that when the residence time is 8 h and the pyrolysis temperature is 500 ℃,the biochar skeleton structure and pore structure are well developed. The adsorption performance of biochar is good,and the desulfurization rate is26.9%.
