摘要： 786,080. Driving bands. LIGMA CHEMICAL CO., Ltd., TAYLOR, S., and ENTWISLE, A. A. C. Jan. 27, 1956 [Feb. 7, 1955], No. 3528/55. Class 80 (1). A driving band comprises an endless cord 3 bound by a covering 4 to form a two-strand band with eyes 5 at its ends which serve for fastening by a suitable hook. The cord 3 may comprise, Fig. 2, a pre-stretched rubber core 1, a textile braiding 2 and an outer rubber sheath 3. The outer covering 4 is a textile braiding. In Fig. 3 strips 6 of moulded rubber are applied to the cords 3 before the outer covering to make up the finished band to a circular cross-section. Loops of nylon or other textile material or wire may be threaded through the eyes 5 for connection by the hook. The band may be finally impregnated with rubber. The two strands may be twisted together before applying the covering 4.

摘要： Disclosed is a method of pretreating biomass in two pretreatment stages as part of a biofuel production process. The first stage pretreatment is carried out by heating the biomass to a first stage temperature of 140°C to 180°C for a first stage time of 30 minutes to 2 hours at a first stage pressure of 105 to 150 psig; and the second stage is carried out by heating the biomass to a second stage temperature of 190°C to 210°C for a second stage time of 2 to 10 minutes at a second stage pressure of 167 to 262 psig. The biomass may be initially conditioned prior to the first pretreatment stage by atmospheric steam heating and adjusting the moisture content of the biomass. Hemicellulose and inhibitors (inhibitory compounds) to downstream hydrolysis and fermentation are preferably removed between the first and second pretreating stages, more preferably after each pretreatment stage.
摘要翻译：公开了在两个预处理阶段中预处理生物质的方法，作为生物燃料生产过程的一部分。第一阶段预处理通过在105至150psig的第一阶段压力下将生物质加热至140℃至180℃的第一阶段温度进行30分钟至2小时的第一阶段时间; 并且第二阶段通过在167-262psig的第二阶段压力下将生物质加热至190℃至210℃的第二阶段温度进行2至10分钟的第二阶段时间。生物质可以在第一预处理阶段之前通过大气蒸汽加热和调节生物量的水分含量来进行初始调节。优选在第一和第二预处理阶段之间去除下游水解和发酵的半纤维素和抑制剂（抑制化合物），更优选在每个预处理阶段之后。

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： A process for the production of ethanol wherein a hydrolyzed lignocellulosic biomass is fermented in the presence of a stillage residue. The fermentation of cellulosic hydrolysates is improved by adding prior to and/or during fermentation a stillage residue side stream from a corn starch-to-ethanol process as a nutrient source for the yeast organisms used in the fermentation. Stillage residues from the grain dry mill ethanol producing process, including the whole stillage, wet cake, thin stillage, and/or syrup are added to assist as a nitrogen and nutrient source for the fermentive processes. The stillage residue is produced by any grain-to- ethanol process.

摘要： Disclosed is an improvement in a conventional process for C5 and C6 sugar recovery from lignocellulosic biomass for fermentation to ethanol, which process including the conventional steps of pretreatment of the biomass with steam at elevated temperature and pressure, collection of C5 sugars from hemicellulose breakdown, cellulose hydrolysis and collection of C6 sugars from cellulose breakdown. The improvement includes conditioning of the biomass prior to the pretreatment step by heating the biomass with steam for a time period between 5 minutes to 60 minutes to achieve a steam treated biomass having a temperature of about 80 to 100oC; and adjusting a moisture content of the steam treated biomass to about 45% to 80%. An increased recovery of C5 and C6 sugars is achieved compared to the conventional process

摘要： A method for optimization of a fed-batch lignocellulosic biomass hydrolysis process wherein the hydrolysis time is minimized by controlling the feed addition volume and / or batch addition frequency of prehydrolysed lignocellulosic feed and optionally the enzyme feed. The increase over time in hydrolysate consistency and volume and / or concentration of sugars released in the reactor, so that the enzymatic hydrolysis is controlled, significantly reduces the impact of cellulase feedback inhibition, especially for enzyme contents lower than 0.5%. The overall time to reach conversion of the total prehydrolysate feed is reduced significantly where the batch addition frequency is equal to one batch each time 70% to 90% of a theoretical cellulose to glucose conversion is reached, preferably when 80% conversion is reached. At an enzyme load of 0.3% in the reaction mixture, the optimum frequency each time 80% conversion was reached was found to be one batch every 105 minutes.
