稀酸和离子液体联合预处理促进甘蔗渣的水解

星期五, 一月 17th, 2014

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%)。 (更多…)

Combination of dilute acid and ionic liquid pretreatments of sugarcane bagasse for glucose by enzymatic hydrolysis

星期五, 一月 17th, 2014

Loss 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. (更多…)

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

星期五, 一月 17th, 2014

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%。 (更多…)

Production of 2,3-butanediol from cellulose and Jatropha hulls after ionic liquid pretreatment and dilute-acid hydrolysis

星期五, 一月 17th, 2014

To make full utilization of raw material and achieve high concentration of sugars in the hydrolysate of biomass, microcrystalline cellulose and Jatropha hulls were pretreated by IL1-butyl-3-methylimidazoliuma chloride ([BMIM]Cl) before their subsequent dilute sulfuric acid hydrolysis. (更多…)
