利用高酸价工业废油制取生物柴油的研究

Trans-esterification of High Acid-value Industrial Waste Oil

以工业废油和甲醇为原料制备生物柴油．研究表明，以氢氧化钠为催化剂，醇油摩尔比最佳取值范围为5．5～7．5，催化剂用量最佳取值为1．0％，反应时间最佳取值为65min，反应温度最佳取值为65℃．产品性能表明其可作为柴油的调和组分，调和出成本低、优质、低凝点的柴油满足特殊需要，产生更大的经济效益和社会效益．

Bio-diesel is produced, in this paper, from industrial waste oil and methanol. Results show that using caustic soda as catalyst, the optimal conditions are： the molar ratio of alcohols and oil 5.5～7. 5, the amount of catalyst 1.0%, the reaction time 65 min and reaction temperature 65 C. The properties of the product show that it can be used as a mingling component of diesel, i： producing a kind of diesel oil of low cost, high benefits and tow freezing point, to meet special needs and gain economic and social benefits.
