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 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 ...

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 ...

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. ...

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 ...

Biodiesel Analysis With Portable Midinfrared Analyzers
Biodiesel sales in the U.S. increased from 75 million gallons in 2005 to 250 million gallons in 2006. As ol September 2007, 165 companies arc producing biodiesel and 85 plants are under construction- Along with this rapid growth in production is the iuviI to ensure quality product* Methods fur specifications offinished biodiesel fuels include ASTM D 6751, ON 14214, and DIN 51606. The rest ...

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 ...
