活性炭烟气脱硫技术研究新进展

研制了新型活性炭脱硫剂－脱硫活性碳纤维。研究表明，脱硫活性碳纤维由于含碳量高、比表面积大、微孔丰富、孔径分布窄、有较多适于吸附ＳＯ２的表面官能团，因而吸附能力及吸附、脱附速度显著大于普通活性炭。在相同工艺条件下，脱硫活性碳纤维吸附容量为粒状疾性炭的４－５倍，空速粒达活性炭的１０倍。采用活性碳纤维脱硫可比普通活性碳脱硫剂用量成倍减少。另外，由于活性碳纤维阻力小，系统能耗可显著降低。活性碳烟气脱硫采用

Monitoring and environmental modeling of earthwork impacts: A road construction case study

This study presents the contributions of materials, earth engineering machines and construction techniques to potential environmental impacts from the main items of typical road earthworks. To achieve this goal, the overall activity at a 1.9-km long French earthworks project site for a heavily trafficked highway was surveyed during its 2007–2009 construction period. Using data collected and a numerical model of road life cycle assessment (LCA), i.e. ECORCE, six indicators could be evaluated, namely: energy consumption, global warming potential, acidification, eutrophication, photochemical ozone creation, and human chronic toxicity. When available, several life cycle inventories were implemented in order to appraise indicator sensitivity with respect to the considered panel of pollutants. Results also allowed estimating from an LCA point of view: (i) the conservation of both aggregates and soil as induced by quicklime treatment and (ii) the duration necessary for projected traffic levels to offset the potential environmental impacts of the earthworks stage.

A review on the formation of titania nanotube photocatalysts by hydrothermal treatment

Titania nanotubes are gaining prominence in photocatalysis, owing to their excellent physical and chemical properties such as high surface area, excellent photocatalytic activity, and widespread availability. They are easily produced by a simple and effective hydrothermal method under mild temperature and pressure conditions. This paper reviews and analyzes the mechanism of titania nanotube formation by hydrothermal treatment. It further examines the parameters that affect the formation of titania nanotubes, such as starting material, sonication pretreatment, hydrothermal temperature, washing process, and calcination process. Finally, the effects of the presence of dopants on the formation of titania nanotubes are analyzed.

Life-cycle assessment: A survey of current implementation

Life-Cycle Assessment (LCA) is an analytical tool that evaluates the environmental consequences of a product, process, or activity across its entire life cycle. LCA is used internationally by government and industry to obtain a comprehensive perspective of the interactions between an activity and the environment and provides a method to systematically identify opportunities for improvement. The framework is integrated into environmental management programs motivated by market awareness, public perception, and cost savings. The use of LCA is driven by external forces such as eco-labels and the recent development of the ISO 14000 standards. However, LCA has many shortcomings that need to be addressed. The concerns of poor data quality, data availability, high implementation costs, subjectivity, and lack of standardization have sent LCA into a state of flux. In light of the recent surge of interest in LCA, the authors of this article have conducted a corporate survey that targets the implementation of LCA. Their goal is to determine the level of activity of LCA among known practitioners and to elucidate common themes. This article presents their findings from responses by 34 companies that were known to be actively involved in LCA or contemplating its future use.
