  • Putting the brakes on biodiesel

      Come December 31st, the Texas Commission on Environmental Quality (TCEQ) is set to effectively ban biodiesel in the state’s largest markets. The problem, they say, lies with the fuel’s nitrogen oxide (NOx) emissions and their contribution to the formation of ground-level ozone in Texas’ eastern counties. According to the TCEQ, biodiesel does not meet the stricter NOx standards recently ...

  • Maintaining biodiesel quality standards

    A problem that is sometimes encountered with biodiesel blends is inaccurate blend ratios. This article describes a quick analytical method to assess blend ratios and ensure fuel performance. According to a study1 done by the National Renewable Energy Laboratory, the chief problem found with biodiesel blends was inaccurate blend ratios. Retail customers and fleet managers do not typically worry ...

  • Microtox aquatic toxicity of petrodiesel and biodiesel blends: The role of biodiesel's autoxidation products

    The authors investigated the acute Microtox toxicity of the water accommodated fraction (WAF) of six commercial soybean biodiesel/petrodiesel blends at different oil loads. We analyzed five fatty acid methyl esters (FAMEs), C10–C24 n‐alkanes, four aromatics, methanol, and total organic carbon (TOC) content. At high oil loads, the WAFs' toxicity was significantly higher for blends containing ...

  • The Effect of Biodiesel Feedstocks on Infrared Blend Measurements

    This White Paper addresses the common concern among biodiesel blenders and distributors as to whether or not biodiesel made from different feedstocks such as soy, waste vegetable oil or palm oil will affect the blend measurement.  The data presented, as well as the chemistry, shows that infrared measurements offer a reliable analytical technique for checking biodiesel blend. Portable ...

  • Biofuels blend measurements with portable mid-infrared analyzers

    Globally, governments are putting more emphasis on sustainable energy sources and are creating energy policies that promote the production and use of biofuels. With the Renewable Fuels Standard-2 (RFS-2), the United States set biofuels blending volumes to 12.95 billion gallons (49.0 billion liters) for 2010, increasing to 36 billion gallons (136 billion liters) by 2022. With similar mandates or ...

  • 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. ...

  • 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 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 ...

  • Biodiesel Analysis with Mid Infrared - From Feedstock to Fuel

    Introduction The biofuels industry is growing rapidly and so is the need for analysis to ensure quality product. The parameters for quality biodiesel require different types of instruments and measurement systems, such as gas chromatographs (GC), titrators, centrifuges, infrared spectrometers... Although claims are out there for the analyzer that will do it all, unfortunately there is no one ...

  • 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 ...

  • Production optimization and quality assessment of biodiesel from waste vegetable oil

    Biodiesel production is worthy of continued study and optimization of production procedures because of its environmentally beneficial attributes and its renewable nature. In Egypt, millions L of oil used for frying foods are discarded each year into sewage systems. Thus, it adds to the cost of treating effluent or pollutes waterways. This study is intended to consider aspects related to the ...

  • The impact of blending techniques, feedstock choice, and analytical techniques on biodiesel blend accuracy

    The National Renewable Energy Laboratory in Golden, Colorado, USA, conducted a nationwide study released in 2005 that compared the actual content of biodiesel in biodiesel/ petroleum diesel blends vs. the nominal content. Results showed that 36% of the samples were incorrectly labeled. Inaccurately blended biofuels can have a negative impact throughout the supply chain, affecting distributors, ...
