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...
The world has been alarmed with the global warming effects. Global warming has been a distress towards the environment, thus shorten the Earth’s lifespan. It is a challenging task to reduce the global...
As the unmanned aerial vehicle (UAV) technology has gained popularity over the years, it has been introduced for air quality monitoring. This study demonstrates the feasibility of customized UAV with ...
Mangroves are important for survival of coastal communities as they provide ecosystem services that support coastal population and their livelihoods. Most coastal communities largely depend on ecosyst...
As representative vulnerable regions of the city, dense distribution areas of temporary color steel building are a major target for control of fire risks, illegal buildings, environmental supervision,...
Humanitarian aid distribution is associated with many activities, numerous disaster management stakeholders, enormous effort and different processes. For effective communication, humanitarian aid dist...
