Today’s vulnerable diesel fuel
When the Environmental Protection Agency (EPA) mandated a change to ultra-low sulfur diesel (ULSD) in 2007, it caused some significant problems for fleets. The majority of fleet managers are not aware of these problems. From fuel microbes to water contamination, here are the problems and how to prevent (or solve) them. 1. Lack of Lubrication Prior to the introduction of ULSD, diesel fuel ...

Taking matters into hand - Case Study
Biofuels must be up to scratch as contaminated or improperly blended fuel can damage a company’s bottom line. To ensure product quality several options exist including laboratory analysis, field test kits and portable lab instruments. Laboratory testing would be the ideal solution if everyone had the budget and the time to wait for the results. But in a market where time is money, quick ...

WTO Rules on EU AD Measures On Biodiesel from Indonesia
On January 25, 2018, the World Trade Organization (WTO) issued a ruling on anti-dumping (AD) measures on biodiesel from Indonesia, following Indonesia’s request for consultations with the European Union (EU) in June 2014. The ruling is the latest in a series of legal challenges to EU AD duties on biodiesel imports from Indonesia and Argentina that were established in 2013. Similar to the ...

Guide to Measuring Biofuel Blending
As the global commitment to renewable energy sources grows, the importance of using biodiesel as a blending component with diesel fuel has increased. Biodiesel consists of fatty acid methyl esters (FAME) which are produced by the transesterification of certain feedstock oils, such as soy, rapeseed, canola, and others. The biodiesel is then blended with diesel fuel at amounts required by the ...

Anaerobic treatment of crude glycerol from biodiesel production
In this study, we evaluated the use of an up-flow anaerobic sludge blanket (UASB) reactor to treat crude glycerol obtained from cottonseed biodiesel production. The laboratory-scale UASB reactor (7.0 L) was operated at ambient temperature of 26.5°C with chemical oxygen demand (COD) concentrations between 0.5 and 8.0 g/L. The volatile fatty acid contents, pH, inorganic salt contents and biogas ...

InfraSpec VFA-IR Spectrometer for Biodiesel Blend Measurements
Synopsis: Simple, yet powerful, filter-based IR spectrometers are ideal for compliance to the new ASTM 7861 test method for accurately measuring biodiesel blend ratios. The Wilks InfraSpec analyzer was the instrument used to develop and validate this method and thus is the industry standard for field measurement of FAME (Fatty Acid Methyl Ester) blend percentages. Introduction: Biodiesel is a ...

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 ...

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 ...

Inclusion of biodiesel and PV modules in a wind diesel hybrid system supplying electrical loads on a small farm
The growing interest in biofuels is a consequence of the need to reduce operating costs of energy systems and the need to reduce emissions of greenhouse gases. The same applies to PV modules, comprising a solution environmentally desirable for power generation. This paper presents a study on the inclusion of biodiesel and PV modules in a system already in operation on a small farm in southern ...

Diesel economy is the benefit for the future
Diesel fuel is a liquid product which is used as fuel in the diesel engine. It is received by oil distillation from kerosene and gas-oil fractions. It represents quite viscous and difficult evaporated combustible liquid. Generally it consists of carbons, some percentage of hydrogen, oxygen, sulfur and nitrogen. Such type of fuels is intended for high-speed diesel and gas-turbine engines of land ...

Development of decision support system to select the best fuel blend in IC engines to enhance the energy efficiency
This paper describes an application of hybrid MCDM technique for the selection of optimum blend in fish oil biodiesel among the six alternative fuel blends diesel, B20, B40, B60, B80 and B100 which is prepared by varying the amount of diesel with biodiesel. Brake thermal efficiency (BTE), exhaust gas temperature (EGT), oxides of nitrogen (NOx), smoke, hydrocarbon (HC), carbon monoxide (CO), ...

Assessment of fuel efficiency of neem biodiesel (Azadirachta indica) in a single cylinder diesel engine
Increase of petroleum diesel usage and its environmental pollution necessitate the study of alternate fuel production. Vegetable oils are the viable alternate form of non–polluted, renewable fuel to diesel engines. In this work, the non–edible oil, neem (Azadirachta indica) was used to produce biodiesel by a two step transesterification process. The fuel properties of the biodiesel thus produced ...

Energy and exergy analyses of a CI engine fuelled with palm biodiesel based on experimental data
Only energy analysis is not enough to define the best efficiencies of any system, so exergy analysis uses to understand and improve the actual efficiencies of the whole system. Energy analysis identified the energy losses but could neither identify the irreversible losses nor their location. These are, however, could be clearly explained with the application of exergy analysis. In this study both ...

Development and measured performance of a batch reactor for biodiesel production from fresh and waste vegetable oils
The development and measured performance of a batch reactor for biodiesel production from fresh and waste vegetable oils as feedstock is presented. A biodiesel batch reactor was fabricated using locally sourced materials. Three different transesterification reactions were performed on the feedstocks using the fabricated reactor. The reaction temperature and time were varied for the fresh and ...

Comparison of infrared biodiesel measurement methods - An overview of ASTM-approved methods and those under consideration
There are several options for measuring the amount of biodie-sel in diesel fuel. Methods EN 14078 and AS'lTvI D7371 are more amenable to laboratory testing although wailing for an off-site laboratory to perform the test can take several hours to several days. For a driver whose truck has just been loaded for a delivery, any wail is too long. Other options for more simplified on-site testing that ...

Get comparable ASTM/EN data for biodiesel blend while saving time and money
If you need to verity how much biodiesel is in a diesel fuel, sending a sample off to a laboratory can take several days to get an answer. This can add unnecessary delays if a truck has just been loaded for a delivery, but must wait for the lab result. The best solution is to have an on-site test where the fuel is loaded or delivered. The two most widely used analytical methods for measuring the ...

Comparison of EN 14078 and ASTM D7371 infrared biodiesel methods
Infrared (IR) analysis is the most widely used measurement technology for measuring biodiesel in diesel. Both EN 14078 and ASTM D7371 methods use infrared as the analytical method and more specifically FTIR (Fourier Transform Infrared) spectroscopy. Infrared is a common spectroscopic technique used for quantitative and qualitative analysis. In the biodiesel measurement, the fatty acid methyl ...
