Lead sorption performance on active silica derived from fly ash
The object of this study was to estimate the sorption property of active silica derived from fly ash after separation of silica and aluminum. The specific surface area of active silica enlarged to 115 m2/g was compared with the original fly ash (4 m2/g). Field emission scanning electron microscopy displayed the active silica, which looked like a honeycomb or curly layer with many lamellae that ...

Performance and emission characteristics of CI engine, fuelled with diesel and oxygenated fuel blends
Vegetable oils are a potential alternative towards partial or total substitution of diesel fuels. In this study, we used ethanol as the solvent, and a bio fuel enhancer as additive to explore the possible use of higher percentages of biodiesel in an unmodified diesel engine. Biodiesel was produced from cashew nut shell liquid (CNSL) by pyrolysis process. A mixture containing 80% (by volume) of ...

Wind Power Beats Nuclear Again in China
China, the country that is building more nuclear reactors than any other, continued to get more electricity from the wind than from nuclear power plants in 2014. This came despite below-average wind speeds for the year. The electricity generated by China’s wind farms in 2014—16 percent more than the year before—could power more than 110 million Chinese ...

How to Choose the Right Solar Panels
Whether you've decided to live "off the grid" or simply work eco-friendly energy into your current lifestyle, using solar energy is an ideal way to accomplish the goal. Using photovoltaic technology, the heat and light from the sun are converted into electrical energy that you can use to power your home. Solar panels are made up of solar cells that contain both a positive and negative layer ...

Method for Computing alkalinity based on Total Inorganic Carbon (TIC) and related data case study
Summary Standard Methods (Ref. 1) has a procedure using nomographs for estimating COt concentrations (Method 4500-CO2 B) based on total alkalinity titrations. The method presented here reverses that process by computing alkalinity based on TIC measurements using infrared technology. These two methods are demonstrated to be compatible, which is not surprising since they use the same stoichiometric ...

GHG balance of biodiesel production and consumption in EU
The promotion of biofuels as energy for transportation in the industrialised countries is mainly driven by the perspective of oil depletion, concerns about energy security and global warming. Nevertheless, the production of biofuels entails emissions to the environment coming from the different stages in the product life cycle. This paper evaluates the environmental impact of pure rapeseed ...
