利用微波反应器系统对棕榈油果空壳纤维酸水解过程的动力学研究
2014-05-19随着气候变化和石油价格的不断上涨，人们日益认识到寻求能源替代品的迫切性，所以国内外研究者纷纷开展农业废弃物转化成高附加值产品的深入研究。在所有可替代资源当中，木质纤维素原料可作为较为理想的碳源。木质纤维素包括纤维素，半纤维素和木质素，其主要来源包括农业废物/残渣，木材，水生植物等途径，可作为生产各种化工原料，如生物乙醇和生物燃料的起始物料。在马来西亚，在棕榈油提取过程中每年大约产生有17万吨棕榈油...

A kinetic study on acid hydrolysis of oil palm empty fruit bunch (EFB) fibres...
2014-05-19Climate change and rising oil prices have urged the needs for researching alternative energy. Among possible alternative resources, lignocellulosic biomass is one of the promising raw materials, which has been intensively studied recently.Lignocellulosic materials consist of cellulose, hemicellulose and lignin. The different sources and type of lignocellulosic materials such as agricultural was...

制备磁性铁酸钙催化剂用于大豆油和小桐子油的转酯化
2014-04-15生物柴油是一种环境友好型可再生能源。开发可回收、再利用的固体催化剂，利用小桐子油为代表的非食用油为原料是生物柴油研究的关键。中国科学院西双版纳热带植物园方真研究员课题组采用共沉淀-煅烧-还原的方法制备具备磁性的固体催化剂CaFe2O4-Ca2Fe2O5-Fe3O4-Fe，在保持较高催化活性的同时，解决了催化剂与产物的分离问题，避免了均相催化中酸液的排放和乳化。该催化剂催化大豆油及小桐子油转酯化制备生物柴油，转化率分别达到...

Transesterification of Soybean and Jatropha Oils by Synthesized Magnetic CaFe...
2014-04-15Biodiesel is an environment-friendly renewable energy. The critical issues on biodiesel studies are the development of recyclable and reusable solid catalyst and the use of non-edible oil such asJatrophaoil as feedstock. Fang’s team from XTBG uses coprecipitation-calcination-reduction method to prepare solid CaFe2O4-Ca2Fe2O5-Fe3O4-Fe catalyst with certain magnetism. This catalyst maintains a r...

离子液体处理后的纤维素和小桐子果壳的稀酸水解液用于2,3-丁二醇发酵
2014-01-17为了充分利用原料和获得具有高浓度糖的生物质水解液，微晶纤维素和小桐子果壳在经过离子液体（[BMIM]Cl）处理后再进行稀酸水解。相比于没有经过预处理的微晶纤维素，离子液体处理后的纤维素在水解后，还原糖的得率和浓度提高了139%, 水溶性产物的得率提高了128%。相比于只经过热水预处理的小桐子果壳，离子液体处理后的小桐子果壳在水解后，还原糖得率提高了80%，还原糖浓度提高了76%，水溶性产物的得率提高了70%。此外，离子液...

稀酸和离子液体联合预处理促进甘蔗渣的水解
2014-01-17半纤维素的损失以及不能有效地破坏纤维素的结晶结构，是木质纤维素水解液中糖得率低以及水解成本高的主要原因。稀酸水解可以有效地将半纤维素水解成糖，而这些糖可以有效地被细菌利用生成2,3-丁二醇(36.1%)。离子液体处理可以有效地破坏纤维素的结晶结构，从而促进后期的酶解。经过稀酸和离子液体联合预处理后，甘蔗渣中纤维素的水解率（95.5%）明显高于只经过稀酸或离子液体处理的材料。这种策略可以高效地从半纤维素和纤维素...

Production of 2,3-butanediol from cellulose and Jatropha hulls after ionic li...
2014-01-17To make full utilization of raw material and achieve high concentration of sugars in the hydrolysate of biomass, microcrystalline cellulose andJatropha hullswere pretreated by IL1-butyl-3-methylimidazoliuma chloride ([BMIM]Cl) before their subsequent dilute sulfuric acid hydrolysis.Compared with original cellulose, after IL-pretreatment, both the yield and concentration of reducing-sugars incre...

Combination of dilute acid and ionic liquid pretreatments of sugarcane bagass...
2014-01-17Loss of hemicellulose and inability to effectively decrystallize cellulose, result in low yield and high cost of sugars derived from biomass. Dilute sulfuric acid pretreatment could easily remove most of hemicellulose as sugars.The sugars were successfully used for 2,3-butanediol production with relative high yield (36.1%). Then, the remained solid residue after acid-pretreatment was further pr...

微波辅助酸水解棕榈果实残渣生产甘露糖
2013-12-18随着化石燃料的逐渐枯竭与能源需求的不断增加，人们越来越认识到寻求能源替代品的迫切性，所以国内外研究者纷纷开展农业废弃物转化成高附加值产品的研究。马来西亚是种植棕榈油料植物最多的国家之一，随着棕榈油的广泛开发利用，棕榈油厂每年生产大约2.39万吨棕榈果实残渣废弃物，经过研究表明其残渣中不仅含有蛋白质，而且其水解产物含有甘露糖，葡萄糖和半乳糖等六碳糖，为微生物发酵生产高附加值化学品提供了较为理想的碳源...
