  • 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 ...

  • Meeting the challenges of biodiesel blend measurements

    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 ...

  • 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 ...

  • 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 ...

  • Parametric study of biodiesel quality and yield using a bench-top processor

    Biodiesel is a renewable liquid fuel alternative to petrodiesel. It is produced by the transesterification of vegetable oil and alcohol in the presence of a catalyst. A 1.5 L bench-top biodiesel processor was constructed to study the effect of feedstock and operating conditions on the conversion and the biodiesel quality. Biodiesel was produced from several oil feedstocks using methanol and ...
