Progress in co-production of biodiesel and lactic acid from rapeseed oil
2012-03-24In April 2011, biomass group (http://brg.groups.xtbg.ac.cn/) in Xishuangbanna Tropical Botanical Garden (XTBG), CAS reported their new progress in biodiesel production and conversion of by-product glycerol to high-value-added products. Related results were published in the international journal “Bioresource Technology” (http://dx.doi.org/10.1016/j.biortech.2011.04.007), and filed a patent.Bio...Catalytic synthesis of biodiesel from Jatropha oil in acidic ionic liquids
2012-03-24In February 2011, biomass group (http://brg.groups.xtbg.ac.cn/) in XTBG, CAS reported their new progress on Jatropha biodiesel production. Results were published in the international journal “Bioresource Technology” (http://dx.doi.org/10.1016/j.biortech.2011.02.079), and filed a Chinese invention patent.Biodiesel is an environment-friendly, renewable, high-qualified and green fuel. Developmen...A new method for producing dye and nano-particles from wood
2012-03-24Wood is mainly composed of lignin (20%), cellulose (50%) and hemicellulose (25%). These components can be catalytic hydrolyzed into their corresponding monomers by conventional enzymes or liquid acids. Among them, cellulose and hemicellulose are hydrolyzed into sugars, such as glucose. Recently, Professor Zhen Fang (http://brg.groups.xtbg.ac.cn/) found that wood could be quickly dissolved and h...Noncatalytic fast hydrolysis of wood
2012-03-24Without any pretreatment (energy-saving) and catalyst (environment-friendly), 99% of wood could be dissolved and hydrolyzed in hot compressed water within several seconds (quickly). Wood particles were rapidly dissolved firstly upon fast heated, and then hydrolyzed into sugars in the hot compressed water. Professor Zhen Fang (http://brg.groups.xtbg.ac.cn/) proposed and built up a controllable r...Progress on the production of biodiesel from Jatropha oil
2012-03-24In July 2010, biomass group (http://brg.groups.xtbg.ac.cn/) in Xishuangbanna Tropical Botanical Garden (XTBG), CAS reported their new progress on continuous production of biodiesel fromJatrophaoil. Jatropha curcas L., as the most promising plant for biodiesel production, receives much attention at both home and abroad. Jatropha oil has a high content of free fatty acids, which results in the lo...Fast dissolution and hydrolysis of wood
2012-03-24Biomass is renewable and rich, and mainly in the form of lignocelluloses. Its annual production is equivalent to ten times of the global energy consumption. Lignin (20%), cellulose (50%) and hemicellulose (25%) are three major constituents of a typical lignocellulosic biomass (e.g., wood and grass), all of which could be hydrolyzed. The production of biofuels based on edible food was unacceptab...Phase behavior and decomposition of lignin in hot-compressed water
2012-03-24Lignin (20%), cellulose (50%) and hemicellulose (25%) are three major constituents of typical lignocellulosic biomass like wood and grass. Among them, lignin is a phenolic biopolymer, which is the most thermal-stable and the most difficult to be degraded by normal biological or thermal methods. Additionallly, it is the industrial waste of cellulosic ethanol and paper making, which makes its rec...Conversion of fructose and glucose into 5-hydroxymethylfurfural with lignin-d...
2012-03-09Renewable biomass is an ideal alternative for fossil resources to supply sustainable raw material for the production of biofuels and chemicals. 5-Hydroxymethylfurfural (5-HMF) is one of the top building-block chemicals from biomass according to the “Top Value Added Chemicals”proposed by the U.S. Department of Energy.It can be produced from hexoses, inulin, wood and other lignocellulosic bioma...离子液体协同固体酸催化果糖和葡萄糖合成5-羟甲基糠醛取得新进展
2012-03-09丰富的生物质资源是将来燃料和化学品持续供应的有前景的选择。在许多可能的生物基化学品中,5-羟甲基糠醛(5-HMF)是精细化工、医药及呋喃高分子材料的有价值的中间底物,可以通过Dials-Alder、烷基化、酰基化、加氢、酯化、卤化、聚合、氧化等一系列化学反应制备多种具有高附加值的衍生物,如PET 的塑料、柴油燃料或其他化工衍生产品,被称之为该领域“沉睡的巨人”。生物能源组(http://brg.groups.xtbg.ac.cn/)郭峰博士和方...Jatropha biodiesel industry in China
2012-02-29Jatrophacurcas L. is chosen as an ideal biodiesel crop in China because its seed kernel has high oil content (43–61%) and it does not compete with food. Its oil is non-edible, and the trees can resist drought and grow on barren and marginal lands without using arable land. Xishuangbanna Tropical Botanical Garden (XTBG) of Chinese acedemy of Sciences (CAS) as a national institute has a long his...Copyright © 2018 BIOMASS GROUP, NANJING AGRICULTURAL UNIVERSITY All Rights Reserved 登录
