    • A process for the production of fatty alcohol or alcohols comprising: subjecting a fatty acid or fatty acid mixture to esterification with a lower alkanol in an esterification reactor maintained under esterification conditions to form a stream comprising the corresponding lower alkyl ester or esters; vaporising the stream from step (a); subjecting the vaporised stream of step (b) to hydrogenation in a first hydrogenation zone operated under hydrogenation conditions to form a stream comprising fatty alcohol or alcohols and an amount of unconverted lower alkyl ester or esters; subjecting the stream from step (c) to transesterification in a wax ester reactor maintained under transesterification conditions in the presence of a solid transesterification catalyst thereby to convert at least a portion of the lower alkyl fatty acid ester by ester interchange with a corresponding amount of fatty alcohol or alcohols to lower alkanol and to a wax ester or esters derived from a fatty alcohol and a fatty acid; separating fatty alcohol or fatty alcohols and wax ester or wax esters of step (d) by distillation to yield a fatty alcohol or alcohols product and a stream comprising wax ester or esters; passing said stream comprising wax ester or esters to a second hydrogenation zone operating under conditions to effect hydrogenation in the liquid phase to revert the wax ester or esters to fatty alcohol or alcohols; and returning the fatty alcohol or alcohols to the separation step (e).
    • 一种生产脂肪醇或醇的方法,包括:在酯化反应器中,在酯化反应器中,用脂肪酸或脂肪酸混合物与低级链烷醇酯化,形成含有相应的低级烷基酯或酯的物流; 蒸发来自步骤(a)的物流; 使步骤(b)的汽化物流在氢化条件下操作的第一氢化区中氢化形成包含脂肪醇或醇的一定量的未转化的低级烷基酯或酯; 将来自步骤(c)的料流在固体酯交换催化剂存在下在酯酯化反应器中维持的蜡酯反应器中进行酯交换,从而通过酯交换将至少一部分低级烷基脂肪酸酯与相应量的脂肪 醇或醇以降低链烷醇和衍生自脂肪醇和脂肪酸的蜡酯或酯; 通过蒸馏分离步骤(d)的脂肪醇或脂肪醇和蜡酯或蜡酯以产生脂肪醇或醇产物和包含蜡酯或酯的料流; 将包含蜡酯或酯的所述物流传递到在液相中进行氢化的条件下操作的第二氢化区,以将蜡酯或酯还原成脂肪醇或醇; 并将脂肪醇或醇返回到分离步骤(e)。

    • A process for the production of fatty acid esters comprising; (a) subjecting a fatty acid or fatty acid mixture to esterification with a lower alkanol in an esterification reactor maintained under esterification conditions to form a stream comprising the corresponding lower alkyl ester or esters and recovering same; (b) recovering an overhead stream from the esterification reactor comprising unreacted lower alkanol, water, and a heavy organic content comprising one or more of lower alkyl ester and/or acids; (c) subjecting the recovered overhead stream to distillation in a first distillation column operating under first distillation conditions to separate a portion of the lower alkanol from a stream comprising the water, the remaining lower alkanol and the heavy organic content; (d) recovering the stream comprising the water, the remaining lower alkanol and the heavy organic content; and (e) subjecting the stream comprising the water, the remaining lower alkanol and the heavy organic content to distillation in a second distillation column operating under second distillation conditions to provide an overhead stream comprising lower alkanol and at least a major portion of the heavy organic content and a water stream having a reduced heavy organic and alkanol content.
    • 一种生产脂肪酸酯的方法,包括: (a)在维持在酯化条件下的酯化反应器中使脂肪酸或脂肪酸混合物与低级烷醇进行酯化,形成包含相应的低级烷基酯或酯的物流并回收; (b)从包含未反应的低级链烷醇,水和包含一种或多种低级烷基酯和/或酸的重的有机物含量的酯化反应器回收塔顶物流; (c)在第一蒸馏条件下操作的第一蒸馏塔中对回收的塔顶馏出物进行蒸馏以从包含水,剩余的低级链烷醇和重的有机物含量的物流中分离一部分低级链烷醇; (d)回收包含水,剩余的低级链烷醇和重的有机物含量的物流; 和(e)使包含水,剩余的低级链烷醇和重的有机物含量的物流在第二蒸馏条件下运行的第二蒸馏塔中进行蒸馏以提供包含低级链烷醇和至少大部分重质有机物 含量和具有降低的重的有机和烷醇含量的水流。
