Lower Resolution Infrared (IR) Spectroscopy Can Provide Higher Performance for Quantitative Biodiesel Measurements
Resolution is often used as a yardstick of instrument performance in Infrared Spectroscopy. This is especially true when the measurements are energy limited as they are in the mid-infrared. For example, in both the European and ASTM standards - EN14078 and ASTM D7371 - for the determination of biodiesel in diesel fuel, a 4 cm-1 resolution is specified which is a relatively high resolution. ...

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 ...

The Effect of Biodiesel Feedstocks on InnfraRed Blend Measurements
What is the effect of biodiesel feedstocks on measurement accuracy? This common question coming from individuals measuring the percent biodiesel in diesel leads to several other questions before the answer is complete. How does infrared measure biodiesel content? Fortunately for manufacturers of infrared instrumentation, biodiesel has a unique signature from diesel in the infrared range of the ...

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 ...

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 ...

Meeting the Challenges of Biodiesel Blend Measurements with Portable Mid-Infrared Analyzers - Case study
In a published paper on biodiesel blend quality submitted by the National Renewable Energy Laboratory1, the chief problem found with biodiesel blends was inaccurate blend ratios. Retail customers and fleet managers do not typically worry about whether the blend ratio is correct until a problem occurs. For fleet managers, an incorrect blend can mean a total shutdown of operations. On the ...

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 ...

Optimisation of injection timing and operating parameters on Jatropha biodiesel engine using RSM
Injection timing, along with engine operating parameters, significantly affects the performance and emissions of Jatropha biodiesel engine. Optimal setting of these parameters is indispensable for efficient operation of diesel engine when fuelled with Jatropha biodiesel. The present work is to optimise these parameters using response surface methodology (RSM) for Jatropha biodiesel operation in ...

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 ...

The Effect of Feedstocks on InfraRed Blend Measurements
IR can be a simple, effective way to measure biodiesel blend ratios from a variety of feedstocks BY SANDRA RINTOUL With biodiesel hitting a new production record of 823 million gallons through October and expected to reach 1.28 billion by 2013, more biodiesel will ultimately be blended into our diesel fuel. This boom in production has opened the doors to a number of potential biodiesel ...

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 ...

Performance analysis of a single cylinder DI diesel engine using different biodiesel
Biodiesel produced from cottonseed oil is quite a promising alternative fuel for diesel engines. Use of vegetable oils in diesel engines leads to slightly inferior performance and higher smoke emissions due to their high viscosity and carbon residue. But the performance of vegetable oils can be improved by modifying them through the transesterification process. The research work discusses the ...

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 ...

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 ...
