High graded gasoline is effect of fuel cavitation
Is that possible to receive mid octane gasoline by mixing of low octane gasoline, with high-octane? It depends of the some factors such as the method of mixing and a gasoline proportion. Really, fuel with demanded octane number can be received by fuel cavitation of a high-octane grade with the low-octane. In practice a demanded proportion of gasoline of two brands for receiving the third ...

Thorium dioxide as a nuclear fuel: a scientometric analysis
The present study is aimed at analysing the growth of publications on thorium dioxide (ThO2). INIS database is used as a source to analyse the focused areas of this field for the period 1970–2011. The database contained 2337 publications on thorium dioxide. The study analysed the broad features of literature on thorium dioxide, focusing on year–wise publications, highly productive countries, ...

Framing land use changes in the expansion of Brazilian ethanol production
Internationally land use change for the expansion of ethanol production in Brazil has been associated with deforestation and CO2 emissions. This association has been denied by important Brazilian actors. To clarify the diverging opinions, a study was made of the expansion of sugarcane plantations. Frame analysis was the tool selected. The conflicting frames identified were named 'ethanol as ...

In situ gas fuel production during the treatment of textile wastewater at supercritical conditionsSupercritical water gasification has recently received much attention as a potential alternative to energy conversion methods applied to aqueous/non-aqueous biomass sources, industrial wastes or fossil fuels such as coal because of the unique physical properties of water above its critical conditions (i.e. 374.8 °C and 22.1 MPa). This paper presents the results obtained for the ...

Thermal behaviour study of senakin coal and Refuse Derived Fuel (RDF) blends during pyrolysis using thermogravimetric analysis
Preliminary Thermogravimetric (TG) studies of pyrolysed Refuse Derived Fuel (RDF)–coal blends (20 to 80%) at various heating rates, 20, 40, 60 °C•min–1 have been performed to develop an efficient locally sourced renewable solid fuel. The characteristics of the coal/RDF blends followed those of the parent fuels in additive manner. Among the tested blends, 50:50 blends showed the optimum blend ...

Fuel Cell Voltage Monitoring Considerations
Knowing what’s happening inside a fuel cell is a critical function, especially as fuel cells are continuing to be developed. One important aspect of this is to measure the voltageof each cell in a stack. Although this may sound trivial, it can be more complex and more expensive than it may at first appear due to high voltages, high channel counts,communication types, etc. There are a few ...

Alternative fuels and managing a diverse fuel portfolio
Alternative fuels are becoming more prevalent in the marketplace at large and particularly within the waste industry. For example, Waste Management recently added its lOOOth natural gas fueled truck to its fleet this past summer. The alternative fuels that are going to work best for your fleet will take some investigation and research, but the prevailing data indicates that these solutions will ...

Biogas as an option for industrial applications
Biogas is typically burned to produce electricity or used as vehicle fuel. This case study analyses possibilities to utilise biogas directly in industrial applications to replace current fossil raw materials. True industrial cases are analysed by considering economic impacts of using either landfill gas or gas produced from biomass. Utilisation of biogas is economically viable and technically ...

US Carbon Emissions Down 7 Percent in 4 Years: Even Bigger Drops Coming
Between 2007 and 2011, carbon emissions from coal use in the United States dropped 10 percent. During the same period, emissions from oil use dropped 11 percent. In contrast, carbon emissions from natural gas use increased by 6 percent. The net effect of these trends was that U.S. carbon emissions dropped 7 percent in four years. And this is only the beginning. Graph on U.S. Energy-Related ...

Advances in flashpoint testing: economic impact
Flashpoint testing is one of the oldest methods of the ASTM D02 Committee on Petroleum Products and Lubricants, which was formed in 1904. The most prevalent standards are ASTM D56 (Tag Method), D92 (Cleveland Method), and D93 (Pensky-Martens Method). These classical techniques, commonly referred to as open-cup and closedcup methods, share a common principle: A test flame is lowered into the ...

On-Site Ethanol in Gasoline Blend Analysis Saves Money and Eliminates Uncertainty in Fuel Blends
The use of ethanol as a gasoline additive has increased dramatically over the past few years and will likely continue to increase. For fuel blenders, this means an added challenge to avoid an incorrect blend that could lead to regulatory fines, loss of customer confidence and damage to equipment. A quick on-site analysis with a portable mid-infrared based analyzer, such as the Wilks InfraCal ...

Conception and optimization of a membrane electrode assembly microbial fuel cell (MEA-MFC) for treatment of domestic wastewater
A membrane electrode assembly (MEA) for microbial fuel cells (MEA-MFC) was developed for continuous electricity production while treating domestic wastewater concurrently. It was optimized via three upgraded versions (noted α, β and γ) in terms of design (current collectors, hydrophilic separator nature) and operating conditions (hydraulic retention time, external resistance, aeration rate, ...

Conception of a Refuse-Derived Fuel (RDF) incineration plant and its environmental benefit
Since landfill ban was realised in July 2009 in Germany, wastes that have a high and middle calorific value must be incinerated. Fossil fuels like oil and coal for the generation of electricity and/or heat can be substituted, so that approximately 4 million tons of CO2 could be avoided. Waste incineration is a possible partial solution for avoiding worst impacts of climate change. This paper ...

Anticipated Indirect Land Use Change Associated with Expanded Use of Biofuels and Bioliquids in the EU – An Analysis of the National Renewable Energy Action Plans
This study represents a first analysis and estimate of the effects of Indirect Land Use Change (ILUC) associated with the increased use of conventional biofuels that EU Member States have planned for within their National Renewable Energy Action Plans (NREAPs). These documents specify how European governments plan to deliver their transport targets under the Renewable Energy Directive (RED). 23 ...

Fuel Quality Monitoring System in Indonesia: case study on gasoline quality improvement
This paper advocates periodical monitoring of fuel quality for conformation to quality standards. The Fuel Quality Monitoring System (FQMS) aims to phase out off-specification fuel from the market by a government initiative. The FQMS in developing countries has rather weak management because the insufficient analytical facilities and unskilled human resources result in inadequate monitoring by ...

Consumption analysis of Solid Oxide Fuel Cells
The characteristics of the Solid Oxide Fuel Cell (SOFC) were introduced. The SOFC system can be divided into ten sections based on the Second Law of Thermodynamics. The fuel specific consumption was taken as the primary indicator to investigate the specific consumption for each section. The Energy-flow Framework Diagram (EFD) was undertaken to modify the system, such as controlling the operating ...

Behaviour of Microbial Fuel Cell in a start-up phase
A Single-Chamber Microbial Fuel Cell (SCMFC) was constructed and run in a sequential feed-and-draw cycle operation. Anaerobic mixed bacterial culture and wastewater obtained from a local municipal wastewater treatment plant were used as biocatalysts and media, respectively. The SCMFC behaviour in a start-up phase was examined using the electrical potential (voltage) profiles, and further ...

Implementation of European energy saving initiatives in Greece and national perspectives
Energy has been throughout history a necessary lever for development and evolution. Utilisation of various energy sources contributed in technological development and made the industrial revolution an actual reality. This process has had its price though, since the irrational use of natural resources and finite energy reserves by sole criteria the convenience in production and the maximisation of ...
