Pyrolysis of rice husk and sawdust for liquid fuel

The paper is focused on studying how to convert rice husk and sawdust into liquid fuel. Rice husk, sawdust and their mixture were pyrolyzed at the temperature between 420℃ and 540℃, and the main product of liquid fuel was obtained. The experimental result showed that the yield of liquid fuel heavily depended on the kind of feedstock and pyrolysis temperature. In the experiments, the maximum liquid yields for rice husk, sawdust and their mixture were 56% at 465 ℃, 61% at 490℃ and 60% at 475℃ respectively. Analysis with GC-MS and other apparatus indicated that the liquid fuel is a complicated organic compound with low caloric value and can be directly used as fuel oil without any up-grading. As a crude oil, the liquid fuel can be refined to be vehicle oil.     

从染料厂有机废液中蒸馏回收二氯苯的研究

采用常压蒸馏和减压蒸馏的方法对酸性染料厂有机废液中的高浓度二氯苯进行回收,并通过气相色谱-质谱联用仪对回收的二氯苯进行定性和定量分析以确定回收率．结果表明,常压蒸馏和减压蒸馏均能有效地回收废液中的二氯苯,常压蒸馏的回收率约88％,减压蒸馏具有相对较好的回收效果,回收率约94％。两种蒸馏方法的选择需要在经济分析的基础上进行确定。     

中国粮食产量不同风险类型的地理分布

论文以中国各省份、各地区历年粮食单产为基本资料,采用统计方法,以风险分析技术为核心,定义粮食产量风险评价指标。在此基础上采用迭代自组织动态聚类分析方法分别对全国地区级和省级粮食生产单元进行了减产风险要素分区和综合风险指数分区,分区的结果反映了粮食生产风险水平的区域分异与各地区孕灾环境、致灾因子性质和生产力水平有密切联系。     

花岗岩类岩体与金矿床成因关系的探讨

花岗岩类岩体与金矿床存在着密切的空间联系，其成因关系一直是矿床学界争论的焦点，目前传统的岩浆热液成因观点仍居统治地位。随着地质资料的积累，高温高压实验技术，尤其是金矿床同位素定年技术的进展，传统观点受到了严峻挑战。成岩成矿的时代与时差、成矿流体的来源和成矿物质的来源等确定金矿床成因类型关键因素的综合研究表明，有密切空间关系的金矿床与花岗岩类岩体之间，在多数情况下两者并无直接的成因联系，金矿床不是岩浆热液成因，而是与大气降水或建造水有关的改造成矿作用的产物。

Effects of the surface chemistry of macroreticular adsorbents on the adsorption of 1-naphthol/1-naphthylamine mixtures from water

The adsorption behaviors of 1-naphthol, 1-naphthylamine and l-naphthol/l-naphthylamine mixtures in water over two macroreticular adsorbents were investigated in single or binary batch systems at 293 K, 303 K and 313 K respectively. All the adsorption isotherms in the studied systems can be adequately fitted by Langmuir model. In the case of aminated macroreticular adsorbent NDA103, 1-naphthol is adsorbed to a larger extent than 1-naphthylamine; while, the opposite trend is found for nonpolar macroreticular adsorbent NDA100. It is noteworthy that at higher temperature（303 K and 313 K）, the total uptake amounts of 1-naphthol and 1-naphthylamine in all binary-component systems are obvious larger than the pure uptake amounts in single-component systems, which is presumably due to the cooperative effect primarily arisen from the hydrogen-bonding interaction between the loaded 1-naphthol and 1-naphthylamine molecules. The simultaneous adsorption systems were confirmed to be helpful to the selective adsorption towards 1-naphthol according to the larger selective index.
