Wood materials used as a means to reduce greenhouse gases (GHGs): An examination of wooden utility poles

There has been growing concern over the build-up of greenhouse gase(GHGs) in the atmosphere, particularly carbon dioxide (CO₂), as acause of global warming. The IPCC Third Assessment Report (2001) suggests two ways in which the choice of materials could berelevant. First, some materials, particularly wood, have the advantage thatthey continue to hold carbon (C)in their cells even after being convertedto products. The implications of this feature are well researched. Second,an area that is not well researched relates to the different energyrequirements for producing similar products made with different materials. Using the findings of recent research, this paper compares the energyrequirements and C emissions of manufacturing a product using wood withthat of other materials. The case study of utility poles demonstrates thepositive C and global warming consequences of the lower energyrequirements of wood in the U.S., compared to other materials such assteel or concrete. It demonstrates that GHG emissions associated withutility poles are a small but significant percent of total US annual emissions. Wood utility poles are associated with GHG emission reductions of 163Terragrams (Tg) of CO₂ when compared with steel poles. This isabout 2.8 percent of US annual GHG emissions, which are estimated atabout 5.28 Petragrams (Pg) of CO₂ annually. Thus, the use ofwooden utility poles rather than steel results in a small but significantreduction in total US emissions.

苯的衍生物在活性炭/水界面上的吸附标准自由能及与其分子结构的关系

测定了25℃时活性炭自水中吸附苯、苯酚、苯胺、对－氯苯酚、苯甲酸、对－羟基苯甲酸、对－氯苯胺、硝基苯、对－氨基苯甲酸、对－硝式苯酚、对－硝基苯胺、对硝基苯甲酸的等温线，它们的等温线均为Langmuir型的，利用Langmuir参数计算了吸吸标准自由能变化△G^0，计算结果表明，△G^0具有加和性，即化合物的△G^0是组成该化合物各基团贡献之总和，化合物的分子量及分子连接性指数与△G^0有近似的线性关系。     

改性沸石对焦化废水中COD的去除研究

本文研究了沸石经NaCl、NaOH、HDTMA(溴化十六烷基三甲胺)改性后对焦化废水中的COD的去除效果.比较得出HDTMA改性沸石对COD的去除能力较好,而且废水的色度明显减小.接着进一步研究了该废水处理过程中的影响因素,包括吸附时间、烘干温度、改性剂HDTMA的浓度、pH值等.结果表明,HDTMA改性沸石处理焦化废水可使其COD的浓度降低至150mg/L以下,这到污水综合排放二级标准.

Global warming related carbon dioxide abatement proposals

The relationship between man-made CO2 emission and atmospheric CO2 concentration has been established. The factors that affect CO2 reduction allotment and the impacts on future energy demand and supply were discussed, in order to help energy policy makers both in developed countries and in developing countries for understanding the fundamental constraint on energy sector resulted from global warming related CO2 reduction, and hopefully in finding a common objective starting point to deal with global warming negotiation in energy sector, and to investigate the optimum stabilization goal and process acceptable to all sovereign countries that based on equity and applicability.
