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...
Methane (CH4), carbon dioxide (CO2) and nitrous oxide (N2)O) are greenhouse gases (GHGs) which cause global warming. Natural sources of GHGs include wetlands and termites. Previous studies have quanti...
High variability due to soil heterogeneity and climatic conditions challenge measurement of greenhouse gas (GHG) emissions as influenced by management practices in the field. To reduce this variabilit...
Mechanical pressure clamps are examples of innovative tools commonly used in the oil and gas industry for arresting leaks from damaged oil and gas pipelines. However, if leaks result from pipeline rup...
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...
Granular zero-valent iron (ZVI) has been widely used to construct permeable reactive barriers (PRB) for the in situ remediation of groundwater contaminated with halogenated hydrocarbons. In the anaero...
Geological penetrating radar combined with drilling and chemical analysis has been applied to investigate leakage pollution of Longpan Road gas station in Nanjing, China. The results indicate that rad...
An experiment was conducted to determine the influence of air-borne particulates exuded from gas flare chambers and rainfall/rain water pH in the rusting of metallic building materials, particularly t...
Gas pipelines are environmentally sensitive because they cross varied fields, rivers, forests, populated areas, desert, hills and offshore and also different parameters in gas transmission progresses ...
A two-phase hollow-fiber (HF) liquid-phase microextraction (LPME) method followed by gas chromatography was developed for quantification of 8 major polybrominated diphenyl ethers at trace level in sew...
This study was set out to investigate the emission characteristics of HCl (in both particle (HClp) and gaseous (HClg) forms), and Cl2 during the trichlorosilane (TCS) burning process under various re...
Pollutant emissions from indoor cooking activities using clean fuels such as natural gas or LPG are strongly influenced by cooking ingredients and cooking methods. In this study, we explore the chara...
New way for preparation for liquid coal oil steady combustion on a 2.75 m horizontal boiler with four annular segment tubes, a water jacket system and a system for measurement of water temperature ins...
In this study we used an oxygen-based bomb calorimetry to combust polyvinyl chlorine (PVC) resin under different oxygen-demanded pressure values, and the generated combustion gas was absorbed by wate...
Significant amounts of ammonia, nitric acid and hydrochloric acid as ammonium particle precursors have been found in urban polluted air. In order to advance understanding the formation and dissociati...
