【摘要】 本文采用玉米油为原料,以氢氧化钠为催化剂利用甲醇酯化法制取生物柴油。研究了反应温度、玉米油和甲醇摩尔比及反应时间对生物柴油产率的影响。结果表明最佳的反应条件为:甲醇和玉米油摩尔比为6︰1,催化剂含量为1%(玉米油质量),温度为50℃,反应时间为20min。此条件下制取的生物柴油有如下特性:密度为0.873g/ml,动力粘度(25℃)为6.72g/cm/s,十六烷值为49,热值为39.46MJ/kg。均与矿物柴油相当。更多还原

【Abstract】 Methanol transesterification reaction of corn oil with NaOH-catalyzed is introduced to produce biodiesel. The operation variables used are temperature, the molar ratio of corn oil to methanol, and reaction times. The results indicated that the optimal reaction conditions for the transesterification of corn oil are: molar ratio of methanol and corn oil 6:1, 1%(wt% corn oil) catalyst at 50 ℃ within 20min. The biodiesel from the corn oil has the following characteristics: density 0.873g/ml, dynamic viscosity 6.72g/cm/s(25℃), cetane indices 49, calorific value 39.46MJ/kg, which are similar to fossil diesel oil.更多还原
