Physicochemical characterization of bio-oil is unstable during the storage.Therefore it is necessary to find a stabilization strategy to retard the aging rate of bio-oil.The purpose of this paper is to describe the aging evaluation of pine sawdust bio-oil for three months and elucidate the effect of different mass dosage of industrial alcohol additive(10%and 20%),additive combination(ethanol: 6.58%,acetonitrile: 1%,methyl acetate: 2.42%)and crude bio-oil(blank)on the physicochemical characterization of bio-oil by fast pyrolysis of 1-5 kg/h bench-scale fluidized bed reactor.During storage,the pH value,viscosity,water content(Karl-Fischer titration),density,heating value,GC-MS,NMR,and FTIR spectroscopies of bio-oils were tested.Results showed that compared to the blank,the final pH values and viscosity of the bio-oils with industrial alcohol addiction and additive combination were increased by 15%and 54%,respectively,while density and heating values were decreased during storage by 4%and 3%,respectively.The changes of water contents were not obvious.

开花是植物生活周期中的重要时期阶段,是植株实现由营养生长阶段向生殖生长阶段转变的标志,是形成种子和果实的前提。因此,研究水稻抽穗期有利于保证水稻产量。前期本课题组已克隆了一个控制水稻成花转化的关键基因RID1(Rice Indeterminte 1),它编码一个C2/H2类锌指结构的转录因子,其T-DNA插入突变体rid1出现“不开花”的表型。根据RID1基因芯片数据中糖代谢相关基因表达量差异显著
玉米(Zea mays L.)是一种常见的异花授粉作物,但是存在一类玉米(通常是爆裂玉米),可以作为父本与普通玉米杂交,但不能作为母本接受普通玉米的花粉,具备单向杂交不亲和性(Demerec 1929)。同时以普通玉米为母本,爆裂玉米为父本的杂交后代也存在显著的偏分离现象,目前认为由其基因组中的一类配子体因子(Gametophyte factor,Ga)控制(Nelson 1952)。为探究玉米杂

钛硅分子筛(TS-1)在以H_2O_2为氧化剂的选择氧化反应中表现出优异的催化性能,受到国内外研究者的广泛关注。本实验室前期采用气溶胶辅助法合成了TS-1分子筛,能有效降低模板剂用量,提高单釜利用率。但所得分子筛尺寸比传统水热合成的TS-1较大,因此可能影响其扩散性能。为解决这一问题,对气溶胶辅助合成TS-1分子筛的合成条件进行了改进。首先通过提高模板剂浓度合成出了更小晶粒尺寸的TS-1;调节模板
To upgrade bio-oil,two upgrading methods were employed: low temperature hydrogenation(150 oC)followed by supercritical upgrading in ethanol(HS)and direct up
蒙古黄芪为豆科黄芪属的多年生草本植物,以根入药,是传统名贵中药,具有补气生阳,固表止汗,脱毒生肌,利水退肿等功效,(很多配方中都要用),市场需求量大。黄芪人工栽培周期长,受外界环境影响大,产量不稳定,远远满足不了市场需求,而野生蒙古黄芪资源濒于枯竭。因此,需求生物技术手段生产蒙古黄芪次生代谢产物势在必行。本文利用蒙古黄芪作为材料,以MS培养基作为基本培养基,通过调整激素的浓度和配比建立起了蒙古黄芪
