内容简介:使用热重分析法(TGA)、热裂解-气相色谱质谱联用法(Py-GC/MS)对不同热解温度(450 ℃、550 ℃和650 ℃)、不同混合比(100:0、75:25、50:50、25:75和0:100)的油菜秆和富氢塑料聚丙烯的共热解行为、热解产物分布规律及共热解过程中存在的协同效应进行了详细的分析研究。TGA结果表明,在相同热解温度条件下,混合物中聚丙烯的比例增大过程中热解反应的速率与强度...
The kinetic parameters for the pyrolysis of biomass of the pitch pine (Rigida pine?P. Mill) were examined by thermogravimetric analysis in the temperature range 25?°C to 700?°C, in which the main deco...
Biorefining of second-generation feedstock gains more attention to improve the living standards and promote circular bioeconomy. The biorefinery concept made an effort to make the environmentally sust...
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: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...
Biomass & Bioenergy is an international journal publishing original research papers and short communications, review articles and case studies on biological resources, chemical and biological processe...
Biomass-derived nanomaterials are becoming increasingly attractive if not indispensable in both academic and industrial fields within the past decades, coupled with growing interest in green chemistry...
Efficient utilization of all three components of lignocellulose—cellulose, hemicellulose, and lignin—impels efficient utilization of carbon dioxide fixed by photosynthesis. Conversion of all three of ...
Aboveground biomass (AGB) estimation is critical for quantifying carbon stocks and essential for evaluating carbon cycle. In recent years, airborne LiDAR shows its great ability for highly-precision A...
Grassland ecology experiments in remote locations requiring quantitative analysis of the biomass in defined plots are becoming increasingly widespread, but are still limited by manual sampling methodo...
Shortly after the explosion of the Chernobyl nuclear power plant (ChNPP) in 1986, radioactive fall-out and contaminated trees (socalled Red Forest) were buried in the Chernobyl Exclusion Zone (ChEZ). ...
Biodiesel from inedible sources has become prominent in last few decades. But it is economically incompatible with petroleum diesel. At the same time, both petro-diesel and biodiesels are concerned wi...
Short rotation coppice (SRC) plantations of fast growing trees in Czech Republic may be grown on approximately 120,000 ha in future, as indicated in the Czech Action Plan for Biomass. Until now, 2,800...
Manual in-situ measurements of geometric tree parameters for the biomass volume estimation are time-consuming and economically non-effective. Photogrammetric techniques can be deployed in order to aut...
Forests have complex vertical structure and spatial mosaic pattern. Subtropical forest ecosystem consists of vast vegetation species and these species are always in a dynamic succession stages. It is ...
