Title
(EN) METHODS AND APPARATUS FOR SEPARATING ETHANOL FROM FERMENTED BIOMASS
(ZH) 用于从发酵生物质中分离乙醇的方法和设备
Abstract
(EN)
A method for separating ethanol from fermented biomass is provided. Fermented biomass that is rich in ethanol is used directly as packing material in a distillation column, and a small amount of waterat the bottom of the column is used to efficiently transfer heat to the biomass at the bottom of the column. The fermented biomass packing has a high ratio of surface area to volume, making an efficient packing material. As vapor condenses on the biomass, diffusion of ethanol/water vapor from the body of the biomass enriches the ethanol concentration at the surface of the biomass. Droplets containing lower concentrations of ethanol drip downwards from the biomass, and vapors containing higher concentrations of ethanol rise upwards from the biomass, resulting in a higher concentration of ethanol at the top of the column than was initially in the biomass.

提供了一种用于从发酵生物质中分离乙醇的方法。将富含乙醇的发酵生物质直接用作蒸馏塔中的填充材料,并且使用所述塔底部处的少量水来有效地将热量传递至所述塔底部处的生物质。所述发酵生物质填料具有高的表面积与体积比,形成有效的填充材料。当蒸气在所述生物质上冷凝时,乙醇/水蒸气从所述生物质主体的扩散使乙醇浓度在所述生物质表面处富集。含有较低浓度乙醇的液滴从所述生物质向下滴落,并且含有较高浓度乙醇的蒸气从所述生物质向上升起,导致与最初在所述生物质中的乙醇浓度相比所述塔顶部处的更高乙醇浓度。
