变温-变压连续法制备生物柴油的方法和系统
摘要：
本发明涉及生物柴油的制备领域，公开了变温‑变压连续法制备生物柴油的方法和系统，该方法包括：将含有油脂和醇的原料直接引入至第一反应器中进行反应，由所述第一反应器的上部得到第一物料；将所述第一物料引入至至少两个串联连接的第二反应器中进行反应，由最后一个第二反应器的上部得到第二物料。本发明提供的变温‑变压连续法制备生物柴油的方法通过将含有油脂和醇的原料直接引入至第一反应器中进行反应而不经过常规的预热反应器能够避免进入预热器中进行预热时会引起沉积物在高压的加热器中积累而使装置无法长周期稳定运行的缺陷。
摘要（英）：

The invention relates to the field of biodiesel preparation, and discloses a method and system of utilizing a temperature variable-pressure variable continuous method to prepare biodiesel. According to the method, raw materials containing grease and alcohols are directly introduced into a first reactor to carry out reactions, a first material is obtained from the upper part of the first reactor; then the first material is introduced into at least two serially connected second reactors to carry out reactions, and a second material is obtained from the upper part of the last second reactor. According to the provided temperature variable-pressure variable continuous method, raw materials containing grease and alcohols are directly introduced into the first reactor to carry out reactions and do not go through a conventional preheating reactor, thus precipitates will not be accumulated in a high pressure heater during the preheating process, and the defect that the system cannot run stablyfor a long term is overcome.
