一种餐厨垃圾快速生产生物柴油的方法及制备的生物柴油
摘要：
本发明提供一种餐厨垃圾快速生产生物柴油的方法及所制备的生物柴油，方法包括如下步骤：（1）预处理：将餐厨垃圾进行分拣、粉碎、真空脱水，获得潲水油；（2）按照甲醇与潲水油的质量比例为（50∶100）～（500∶100）称取甲醇、潲水油，按照催化剂占油的质量百分比为0.05～5%称取催化剂；（3）将催化剂溶解在甲醇中，再将潲水油和溶有催化剂的甲醇加入到高压反应釜中，反应温度为80～350℃，反应压力为1～10MPa，反应3～60分钟；（4）反应结束后，进行减压蒸馏，回收过量的甲醇，再将产物进行静置分层，下层为甘油，上层为生物柴油。本发明提供的方法具有反应时间短、反应条件温和、产品后处理简单的特点。
摘要（英）：

The invention provides a method for rapidly producing biodiesel from kitchen garbage and produced biodiesel. The method comprises the following steps of: (1) carrying out pretreatment: enabling the kitchen garbage to be subjected to sorting, crushing and vacuum dewatering, thereby obtaining hogwash oil; (2) weighing methanol and the hogwash oil in accordance with that the mass ratio of the methanol to the hogwash oil is (50: 100) to (500: 100), and weighing a catalyst in accordance with that the catalyst accounts for 0.05-5% by mass of the oil; (3) dissolving the catalyst in the methanol, and adding the hogwash oil and the methanol where the catalyst is dissolved to an autoclave for reacting for 3-60 min at the temperature of 80-350 DEG C and the pressure of 1-10 MPa; and (4) after the reaction is completed, carrying out reduced-pressure distillation, recovering excessive methanol, and enabling a product to be subjected to standing for layering, wherein a lower layer is glycerine, and an upper layer is the biodiesel. The method provided by the invention has the characteristics of short reaction time, mild reaction conditions and simple product post-processing.
