    • This invention relates to a process for conducting equilibrium-limited reactions, such as esterification and alcoholysis reactions, that uses two reaction zones. The first reaction zone operates under reaction conditions that retain at least a portion of the product in a liquid phase, and at least a portion of the liquid from the first reaction zone is introduced into a second reaction zone which operates under conditions sufficient to crack heavies, for example, Michael-addition heavies, formed in or introduced into said second reaction zone and to vaporize at least a portion of the product upon production thereof. Such a process allows for removal of product from the reaction system while catalyst desirably remains in the reaction system.
    • 本发明涉及一种使用两个反应区进行平衡有限反应的方法,如酯化和醇解反应。 第一反应区在反应条件下操作,该反应条件保留产物在液相中的至少一部分,并且来自第一反应区的至少一部分液体被引入第二反应区,其在足以破裂重质的条件下操作 例如,形成或引入所述第二反应区的迈克尔加成物重质物,并在其生产时汽化至少一部分产物。 这种方法允许从反应体系中除去产物,同时催化剂理想地保留在反应体系中。

    • Method and apparatus for producing biodiesel fuel, i.e., alkyl ester, from vegetable and/or animal oil. A transesterification catalyst is prepared in a base catalyst tank by spraying alkyl alcohol under pressure through jets at metal hydroxide pellets until the pellets have fully reacted with the alcohol. The oil is heated and transesterified in the presence of alkyl alcohol and the transesterification catalyst in a closed, recirculating transesterification flow system under slight cavitation to yield product alkyl ester and product glycerol. Cavitation is achieved by permitting air to enter the transesterification flow system through an adjustable air inlet valve. When permitted to stand, product alkyl ester forms an upper layer that is decanted and subjected to purification steps, to remove particulates and alkyl alcohol from the product alkyl ester, and a lower layer of product glycerol is drained away. Purification of the product alkyl ester preferably includes subjecting the product alkyl ester to an overhead water mist in a wash tank with simultaneous infusion of a stream of air bubbles. Alcohol vapor is reclaimed as liquid alcohol within an alcohol condenser and stored for reuse. If the oil contains free fatty acids, prior to transesterification, the oil is heated and the free fatty acids are esterified in the presence of an esterification catalyst and alkyl alcohol. For safety, baffles and explosion damper/flame arrestors are provided in locations where flammable vapors pose a risk.
    • 用于从植物油和/或动物油生产生物柴油燃料(即烷基酯)的方法和装置。 在碱性催化剂罐中通过在压力下喷射烷基醇在金属氢氧化物颗粒中喷射来制备酯交换催化剂,直到颗粒与醇完全反应。 将油在烷基醇和酯交换催化剂存在下在密闭的循环酯交换流动体系中加热和酯交换,在轻微气蚀下得到产物烷基酯和产物甘油。 通过允许空气通过可调节进气阀进入酯交换流系统来实现空化。 产物烷基酯当被允许放置时,形成倾析并经过纯化步骤的上层,从产物烷基酯中除去微粒和烷基醇,并将产物甘油的下层排出。 产物烷基酯的纯化优选包括使产物烷基酯在洗涤槽中的顶部水雾下同时输入气泡流。 酒精蒸汽在酒精冷凝器内作为液体酒精回收并储存以供重新使用。 如果油含有游离脂肪酸,则在酯交换前,加热油,游离脂肪酸在酯化催化剂和烷基醇存在下酯化。 为安全起见,挡风玻璃和爆炸阻尼器/阻火器在易燃蒸汽造成风险的地方提供。
