基于生物质真空热解液化技术的生物油制备（Biomass Vacuum Pyrolysis Liquefaction System for Bio-oil）
生物质能 生物油 真空热解
2009/5/22
以杉木屑、玉米秸秆和稻壳等7种生物质为原料，在自行研制的真空热解装置上进行生物质真空热解制取生物油的实验研究。7种生物质的生物油产率均大于55%，杉木屑的生物油产率达67%以上。生物油成分分析结果表明，生物油是一种含氧量较高的有机混合物，7种生物油所含化合物类型相似，但具体化学组分及其相对含量有所差别。杉木屑生物油中苯酚及其衍生物的含量较高，达72.81%，仅杉木屑生物油中含有丁香酚，丁香酚的相对...
Scaling of two-phase capillary pressure-saturation relationships: water-air and oil-air systems
immiscible phases capillary pressure-satura- tion relationship interfacial tension scaling
2008/12/2
Solutions of various problems related to soil contamination by nonaqueous phase liquids (NAPL) require a knowledge of capillary pressure-saturation relationships. In soil-water-air systems, this rela...

An investigation was carried out on the effect of hydraulic press parameters such as press cage diameter (D) (80, 120, and 150 mm) and wall pore diameter (H) (4, 6, and 10 mm) and expression pressure ...
Effect of mineral vs. biofertilizer on growth, yield, and essential oil content of fennel (Foeniculum vulgare Mill.)
Azotobacter chroococcum Azospirillum lipoferum Bacillus megatherium (Foeniculum vulgare Mill.)
2008/11/21
In field experiments during two successive seasons (2003-2004 and 2004-2005), the effects of biofertilization on growth, fruit yield, and oil composition of fennel plants were investigated. Applicatio...
Effect of spent engine oil on soil catalase and dehydrogenase activities
catalase dehydrogenase soil engine oil
2008/11/20
The effect of spent engine oil on soil pH as well as activity of selected enzymes (catalase and dehydrogenase) was studied. The results indicate that spent engine oil caused a slight change in soil pH...
