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...

我园博士研究生田霄参加拿大第98届制浆和造纸学会年会暨第二届国际生物冶炼研讨会
2012-02-092012年1月30日-2月3日，加拿大第98届制浆和造纸学会 (PAPTAC)年会 (Paperweek 2012 Canada) 暨第二届国际生物冶炼研讨会（the 2ndInternational Forest Biorefinery Symposium）在蒙特利尔市举行。来自加拿大、法国、美国、瑞典、芬兰等国制浆和生物质冶炼领域的企业主、管理与经营决策经理、学界科研人员、工程师和政府官员共计近500人齐聚蒙城，共同探讨当前国际经济形势下传统产业面临的挑战和发展森林生物质冶炼产业的机遇...

以小桐子壳水解糖发酵生产2,3-丁二醇的工艺取得新进展
2011-12-26面对环境恶化和能源短缺的潜在危机，以生物质资源为替代原料，生产能源和化学品的生物冶炼技术受到广泛地关注。其中，利用小桐子生产生物柴油是研究热点之一。随着小桐子产业的发展，大量废弃小桐子壳也随之产生。这些果皮通常被直接烧掉或掩埋，造成了资源的极大浪费。小桐子壳的主要成分是木质纤维素，其中纤维素和半纤维素含量分别达果皮重量的43%和15%。如果加以利用转化成高附加值的精细化学品，不仅变废为宝，创造出较高...

木质素基固体酸直接催化高酸值小桐子油制备生物柴油
2011-12-07生物柴油的主要化学成分为长链脂肪酸单酯，具有润滑性能好、燃烧充分、储运安全、抗爆性好、环境友好等特点，可以作为石化柴油代用品或与石化柴油混合使用。在过去的10年里，全球生物柴油市场呈现出极速稳定的增长。原料成本占生物柴油生产成本的60～80%，廉价油脂原料的寻找和开发成为必然趋势。生物柴油的高需求和大量生产，必然引发可再生原料的全球投资热潮，如非食用原料如动物油脂、小桐子油、亚麻油、油藻等。然而廉价的...
