Description

采用无催化剂甘油酯化地沟油生产环保船用燃料油调合组分 的方法
技术领域
本发明涉及一种采用无催化剂甘油酯化地沟油生产环保船用燃料油调合组分的方法，属于生物质化工及再生能源领域。
背景技术
地沟油对人类健康的损害和对环境污染是巨大隐患，社会一大问题，而地沟油化工再利用，做成再生能源是有效的解决办法。生物柴油、航空生物煤油是很好的思路和方法，但是工艺复杂，成本高，过程使用催化剂等也产生一定污染处理问题，而通过无催化剂、加热、真空甘油酯化地沟油变成生物燃料，用作船用燃料油的调合组分，工艺简单，方法环保，无污染产生，生产成本低，易工业化。
一些专利，也提出利用地沟油甘油酯化工艺，降低酸值，以进一步进行酯交换和精馏生产生物柴油。如专利CN201310308470.x“一种对地沟油的甘油酯化方法”；专利CN201410557750.9“甘油酯化降低地沟油或酸化油酸值的改进工艺”；但都未能解决地沟油作为生物燃料，特别是环保型船用燃料油调合组分的要求。
地沟油与石油产品渣油、轻组分油的相容性为1级【ASTM D4740-04（R2009）】、含硫低，但要作生物燃料，受限于酸值、灰分、倾点，本发明使用的地沟油酸值为：192.25mgKOH/g，GB/T 264或GB/T 7304，灰分：0.212%（m/m），GB/T508，倾点：35℃，GB/T3535，因此要通过生物质化工处理，使其符合要求。
发明内容
本发明的目的是提供一种工艺简单、方法环保、无污染产生和生产成本低的采用无催化剂甘油酯化地沟油生产环保船用燃料油调合组分的方法。
本发明提供的采用无催化剂甘油酯化地沟油生产环保船用燃料油调合组分的方法，其特征在于，将地沟油甘油酯化，使其成为酸值≤6.5mgKOH/g；灰分≤0.1%；倾点≤30℃的生物燃料油。
上述中，地沟油甘油酯化工艺条件为：地沟油：甘油的质量比为3.0～8.0：1，反应温度为230℃～260℃，反应压力为4.0×104Pa～7.0×104Pa，反应时间3～6小时。
本发明的另一目的是提供一种环保船用燃料油，该环保船用燃料油由上述所得的生物燃料油与含硫量≤0.5%的石油产品渣油、轻组分油调合成含硫量≤0.5%而得。
上述中，按质量百分比计，生物燃料油占15%～25%。
本发明的优点是：通过无催化剂、加热、真空甘油酯化地沟油变成生物燃料油，用作船用燃料油的调合组分，工艺简单，方法环保，无污染产生，生产成本低，易工业化。
