    • A process for producing an alcohol from a fatty acid ester, a fatty acid triglyceride or a fatty acid by continuously catalytically reducing the starting material in the presence of a hydrogenation catalyst is disclosed. In the process of the present invention, two reactors (i.e., the main reactor located upstream and the after reactor located downstream) being located in series are employed. In the process of the present invention, two reactors are employed and the temperatures thereof are individually controlled, whereby the conversion ratio is elevated while suppressing the formation of hydrocarbon and aldehyde by-products. Thus, an alcohol of extremely high quality and high purity can be produced. Further, the process of the present invention makes it possible to omit any post-treatment for eliminating the by-products. Furthermore, the active life of the hydrogenation catalyst can be remarkably prolonged by using three reactors (i.e., the guard reactor, the main reactor and the after reactor).
    • 公开了一种通过在氢化催化剂的存在下连续催化还原原料从脂肪酸酯,脂肪酸甘油三酯或脂肪酸制备醇的方法。 在本发明的方法中,使用两个反应器(即,位于下游的位于反应器的主反应器和位于下游的反应器)串联。 在本发明的方法中,使用两个反应器,并且单独控制其温度,由此转化率提高同时抑制烃和醛副产物的形成。 因此,可以生产出高质量和高纯度的醇。 此外,本发明的方法使得可以省略用于消除副产物的任何后处理。 此外,通过使用三个反应器(即保护反应器,主反应器和后反应器),氢化催化剂的活性寿命可以显着延长。
