内容简介:本研究运用热重分析(TGA)、傅里叶变换红外光谱(FTIR)及热裂解-气相色谱/质谱仪(Py-GC/MS)对废轮胎与农林废弃物(棉花秸秆、花生壳和杨树枝)进行了共热解分析。通过对废轮胎与棉花秸秆、花生壳、杨树枝进行共热解的热重分析,测定了质量损失率和烃含量的协同效应。相比单独热解,废轮胎与棉花秸秆、花生壳或杨树枝的共热解使质量损失率明显增加和烃含量明显增加。农林废弃物的加入简化了热解过程...
内容简介:本文从提高产品质量、提高能源生产和减少环境污染的角度出发,研究了农业生物质废弃物和塑料废弃物的共热解机理。本研究通过采用热裂解-气相色谱质谱联用法(Py-GC/MS)研究了不同种类塑料(聚对苯二甲酸乙二醇酯PET、聚丙烯PP、聚氯乙烯PVC)与油菜杆共热解过程中产物分布的特性。结果表明,不同种类塑料对油菜杆的共热解产物种类影响不大,对热解产物的含量和产量存在显著差异。油菜杆和PET的共热...
内容简介:生物质与废旧轮胎的热化学转化是利用废弃资源生产可再生能源的重要方向。本研究采用热裂解-气相色谱/质谱联用仪(Py-GC/MS)分析了农林业剩余物和废轮胎共热解过程中的产物分布和协同效应。在550°C和650°C的条件下分析了玉米秸秆、小麦秸秆、废轮胎以及小麦秸秆-废轮胎(质量比为1:1)和玉米秸秆-废轮胎(质量比为1:1)的混合物的热解和共热解产物。结果表明农林业剩余物和废轮胎共热解促进...
Asia, being the largest continent, both in its size and population is affected by different types of atmospheric aerosols. Also, owing to different local emissions/sources along with the long range tr...
East China is among the fastest developing area in Asia, where atmospheric aerosol loading is high due to heavy urban and industrial emission. The Moderate Resolution Imaging Spectroradiometer (MODIS...
Few studies have measured the impacts of mowing on bird use of habitat and the risk of bird collisions with aircraft on North American airfields. The need for this research has increased as airfields ...
Marstonia lustrica is a poorly understood aquatic snail, relatively rare throughout its range and listed in the State of Massachusetts as Endangered (MNHESP 2010, Hershler et. al 1987). It is the nort...
In making the gas-solid-liquid phase analysis, based on the collaborative study of the internal and external humidification ratio of desulfurization efficiency, determine the humidifier ratio within 6...
Ambient PM2.5 was sampled in three indoor environments (a common office, a photocopy room and a student dormitory) and one outdoor environment (a rooftop) on a campus of Nanchang University in Nancha...
The metal distribution in the emissions of a laboratory waste incinerator (LWI) was investigated. The input materials and output materials (fly ash, bottom ash, and flue gas) were analyzed to examine...
The study aimed at assessing the distribution and composition of dust produced at Pomona Stone Quarry mine in Harare, Zimbabwe. The source contribution to ambient PM2.5 and PM10 dust levels were quant...
The presence of ionizing sources is a high-risk condition if related to a poor management of the hygiene and health of the anthropic environment. Increased hazard derives from the addition of artifici...
Seasonal variation of antimony was studied in order to characterize its distribution in estuarine water, pore water, sediment, and digenetic behavior in the Sundarbans mangrove ecosystem. The mean con...
Organotin and organolead compounds were determined in sediments of the Suez Gulf The concentrations of Tributyltin (TBT) ranged from 0.27 to 2.77 with an average value of 1.37 礸g-1; dry wt. However, t...
A study was undertaken to assess the distribution behaviour of Dimethoate in tea leaf. Tea bushes were subjected to Dimethoate spray at recommended dose and double the recommended doses. The extractio...
