Abstract: In one aspect, a process for treating woody plant material is provided, the process involving contacting the plant material with a continuous flow of an aqueous ethanol solution at elevated temperature and pressure under conditions that promote extraction of ethanol-soluble lignin from the plant material and retention of hemicellulose sugars, xylose and cellulose in the treated plant material solids. In another aspect, a process for extracting hemicellulose sugars from lignin-depleted plant material solids is provided, the process involving contacting lignin-depleted plant material with water at elevated temperature and pressure under conditions that promote extraction of hemicellulose sugars from the plant material; and recovering hemicellulose sugars from the liquid mixture.

Abstract: An integrated process for the production of ethanol from woody plant material is provided, the process comprising: contacting a continuous flow of the plant material with a counter-current continuous flow of an aqueous ethanol solution at elevated temperature and pressure to provide plant material depleted of lignin; removing ethanol from the lignin-depleted plant material; contacting a continuous flow of the lignin-depleted plant material with water at elevated temperature and pressure to solubilize xylose within the plant material; and hydrolyzing cellulose present in the plant material to form glucose, which in turn is fermented to produce ethanol.
Abstract translation: 提供了用于从木质植物材料生产乙醇的综合方法，该方法包括：在高温和高压下使植物材料的连续流与逆流的乙醇水溶液连续流动接触，以提供耗尽的植物材料 木质素 从木质素贫乏的植物材料中除去乙醇; 使木质素贫乏的植物材料的连续流动在升高的温度和压力下与水接触以在植物材料中溶解木糖; 并水解存在于植物材料中的纤维素以形成葡萄糖，其又被发酵以产生乙醇。
