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...
In 2019, MIT’s Environment, Health, and Safety (EHS) Office collaborated with several research labs in the Department of Biology to determine the feasibility of recycling clean lab plastics. Based on ...
The accumulation of plastic waste in the oceans, soil, and even in our bodies is one of the major pollution issues of modern times, with over 5 billion tons disposed of so far. Despite major efforts t...
Styrofoam egg cartons, hard plastic compact disc cases, red drinking cups and many other common products are composed of polystyrene, a type of plastic that makes up a third of landfill waste worldwid...
The Eighth International Symposium on Engineering Plastics (EP’2017 Xi’an) will be held in Xi’an, Shaanxi Province, China August 8-11, 2017. Its topics will remain on polymeric materials, retaining it...
The ability to change shape and control curvature in 3D structures starting from planar sheets can aid in assembly and add functionality to an object. Herein, we convert planar sheets of shape memory ...
WEST LAFAYETTE, Ind. – An emerging class of electrically conductive plastics called "radical polymers” may bring low-cost, transparent solar cells, flexible and lightweight batteries, and ultrathin an...
Highly-durable extreme-performance plastics and rubbers for use in industries ranging from automotive to construction are now closer to realisation, thanks to a $1 million investment in a Brisbane mat...
Workers handling and painting with powdery paint have a risk of unintentional exposure to nano-particles during their work. Nano-particles in powdery paint were observed by transmission electron micro...
Purpose: Literature consists a lot of information concerning the issues of the fatigue endurance of metals coated with plastics. However few studies explicitly explain, what mechanisms decide on the i...
This paper presents the basic principles of three different types of separating methods and a general guideline for choosing the most effective method for sorting plastic mixtures. It also presents th...
A novel method to discriminate between the residues of kerosene or gas oil and the residues of domestic plastics in fire debris was developed based on the analysis of alkylcyclohexanes by gas chromat...
