In 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. （更多…）
In 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. （更多…）
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”。 （更多…）
Renewable 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 biomass with catalysts. 5-HMF can be further converted into biochemicals and biofuels, such as PET plastics, 2,5-dimethylfuran and other liquid alkanes that can be used as transportation fuel. （更多…）
Jatropha curcas 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 histroy in study and commercialization of Jatropha industry, and made great progress in Jatropha plantation, breeding and crude oil processing. Two new high-seed/oil yield varieties (Jatropha nigroviensrugosus CY Yang; Jatropha curcas cv. multiflorm CY Yang) were bred. Novel green processes to produce biodiese, such as a two-step method using ultrasonic radiation, one-step process using ionic liquids and nanocatalysts, were also developed. （更多…）
