内容简介:有机固体废弃物的热转化是获得单环芳烃的一种相对经济可行的方法。为了明确不同热解温度、混合比和热解反应时间对生物质和塑料共热解制备单环芳烃的影响,并寻求最佳实验条件,本研究以玉米秸秆和聚苯乙烯塑料为原料,利用热裂解-气相色谱质谱联用法(Py-GC/ MS)对单环芳烃含量进行分析。同时,利用响应面分析方法,通过三因素三水平的响应面优化试验,建立玉米秸秆和聚苯乙烯共热解制备单环芳烃的二次回归方...
Some engineering properties of mahogany seed and kernel were investigated and expressed as a function of moisture content. In the moisture ranges of 7.1–32% and 5.3–22% (d.b.), respectively, the seed ...
Otoliths of cultured sea bass and ambient waters were sampled from 24 fish cages and ponds in Malaysia to investigate the contents of Sr, Mg, Ba, Cd and Zn. The following elements content in otolith a...
In this work, a radiological technique which simultaneously measures soil bulk density and water contents accurately and quickly in a non-destructive manner at different depths of the soil profile of ...
Approach: The soil samples were collected from 2 districts of Baia Mare: Ferneziu, which is located in the proximity of a lead smelter and Săsar district which is located along the Săsar Riv...
Drained and undrained triaxial compression tests were run on undisturbed samples of two unsaturated cohesive soils to study water content changes in drained and undrained conditions along shear planes...
Search for a biogeochemical archive of past sulfur pollution is motivated by the need to predict ecosystem health. Sofar, no indicator of local-scale S pollution has existed, while long-range transpor...
Physical and chemical characteristics of particles from rubber-wood combustion in a natural rubber sheet smoking process were studied. Experimental parameters include wood moisture content and wood-b...
Non-destructive monitoring of soil water content (W) and the electrical conductivity of the soil solution (ECw) has been desired for environmental evaluation and sustainable agriculture. Dielectric pr...
