摘要： A process for separation of solid and liquid components in a distillation whole stillage utilizing airless spray drying is disclosed, which is more efficient and economical than conventional processes. In the process, distillation whole stillage resulting from distillation of fermented biomass is first subjected to an evaporation step for separating the whole stillage into a condensate and a concentrate including water, dissolved solids and suspended solids. The concentrate is then subjected to airless steam spray drying for converting the concentrate into dried solids, steam and vapors. All steam and vapors resulting from the airless steam spray drying step are then redirected as energy source to a processing step upstream of the airless spray drying step. At least some of the steam generated in the airless spray drying step is airless steam.

摘要： The use of a side stream and residue from the lignocellulose to ethanol process for use in preventing the formation of ice and in melting ice and snow on roadways. The future lignocellulose to ethanol industry will provide a significant proportion of these streams that provide an organic solution that when added to chloride salts of calcium, magnesium and sodium provides an improved environmentally friendly road deicing product with reduced corrosiveness and increased friction. A deicer composition of calcium chloride aqueous solution containing 25-38% by weight calcium chloride mixed up to 50% by volume of hemicellulose hydrolysis side stream can reduce the corrosivity of calcium chloride to 70% less that of a sodium chloride solution.

摘要： A continuous process for the recovery of ethanol from hemicellulose and cellulose from lignocellulosic biomass. Yield of fermentable sugars can be maximized by continuous operation of the pre-treatment system and careful selection of pretreatment conditions including the addition of only small amounts of dilute mineral acid and low pressure. With this approach, the xylose component that is mainly present in its unfermentable oligomeric form in known pre-hydrolysis Kraft processes can be recovered more efficiently and as a monomer that can be fermented by xylose fermenting yeasts and bacteria. Due to the use of only dilute acids, there is a very low loss of glucose and xylose hence very low production of toxic chemicals (e.g. HMF, furfural) in the pretreatment step. The resulting overall fermentation efficiency of both hexose and pentose sugars is 90 % of the theoretical maximum.
摘要翻译：从木质纤维素生物质从半纤维素和纤维素回收乙醇的连续方法。可以通过预处理系统的连续操作和仔细选择预处理条件（包括仅添加少量稀无机酸和低压）来最大化可发酵糖的产率。通过这种方法，在已知的预水解牛皮纸方法中主要以其不可发酵的低聚形式存在的木糖组分可以更有效地回收，并且可以作为可通过木糖发酵酵母和细菌而发酵的单体。由于仅使用稀酸，葡萄糖和木糖的损失非常低，因此在预处理步骤中有毒化学品（例如HMF，糠醛）的产生非常低。所得到的己糖和戊糖的总发酵效率为理论最大值的90％。

摘要： A process for separating the components of lignocellulosic biomass for the purpose of producing a pure reactive cellulose is disclosed. The process has two stages. In the first stage, the lignocellulosic biomass is pretreated with steam, with or without an acid catalyst and then pressed, with or without the presence of an eluent. to remove hemicellulose and other impurities. In the second stage, the pretreated biomass is extracted with a solvent such as ethanol with or without acid catalysts in order to remove lignin and release a purified cellulose stream. The extracted cellulose is then rapidly decompressed to rupture the fibrous structure. The process provides a purified cellulose stream that is relatively easy to hydrolyze with enzymes and ferment to biofuels and other chemicals such as ethanol.

摘要： A process for the pretreatment of lignocellulosic biomass is disclosed. The process is intended for use in connection with biomass to ethanol processes and is directed in particular to an economical removal of inhibitory compounds generated in biomass pretreatment, which are inhibitory to downstream hydrolysis and fermentation steps. The process includes the steps of heating the lignocellulosic biomass with steam to a preselected temperature, at a preselected pressure and for a preselected time to hydrolyze and solubilize hemicelluloses in the biomass; explosively decomposing the biomass into fibers, and extracting from the resulting reaction mixture a liquefied portion of the lignocellulosic biomass before or after explosive decomposition. The liquefied portion is extracted to remove compounds from the lignocellulosic biomass which are inhibitory to enzymatic cellulose hydrolysis and sugar fermentation to ethanol. For improved efficiency and economy, the inhibitory compounds are not completely removed. Furthermore, xylose has been found to be a good indicator compound for the general level of inhibitory compounds in the reaction mixture and the extraction step is therefore controlled on the basis of the xylose content in the reaction mixture. In particular, the extracting step is discontinued once a dry matter (dm) content of xylose, as monomer or oligomer, in the reaction mixture of 4% to 8% (w/w dm) is achieved. This most economically balances the practical need for inhibitory compound removal with the economical need to control and preferably minimize the costs of the overall ethanol production process.
摘要翻译：公开了木质纤维素生物质的预处理方法。该方法旨在用于与生物质与乙醇方法有关的用途，特别涉及经济地除去生物预处理中产生的抑制性化合物，其抑制下游水解和发酵步骤。该方法包括以预选压力将木质纤维素生物质用蒸汽加热至预选温度并预选水解和增溶生物质中的半纤维素的步骤; 将生物质爆炸分解成纤维，并从所得反应混合物中提取爆炸物分解之前或之后的木质纤维素生物质的液化部分。提取液化部分以从木质纤维素生物质中除去抑制酶纤维素水解和糖发酵成乙醇的化合物。为了提高效率和经济性，抑制性化合物不能完全去除。此外，已经发现木糖是反应混合物中一般水平的抑制化合物的良好指示剂化合物，因此提取步骤是基于反应混合物中的木糖含量进行控制的。特别是，一旦实现4％至8％（w / w dm）的反应混合物中的木糖，作为单体或低聚物的干物质（dm）含量，则提取步骤停止。这最经济地平衡了抑制性化合物去除的实际需要与经济的控制需求并且优选地最小化整个乙醇生产过程的成本。
