  • 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 ...

  • Biodiesel fuel for transportation: Status and issues in the United States

    The United States consumed 3.39 billion barrels of gasoline, 1.54 billion barrels of diesel fuel, and 0.59 billion barrels of jet fuel in 2007. And it currently imports 3.66 billion barrels of oil and petroleum products per year, 65% of US consumption, compared to 1.71 billion barrels (or 36%) 20 years ago. To address the growing gap between petroleum consumption and domestic production, the US ...

  • Assessment of the EU target on renewable energy for transport in the framework of the European vegetable oil sector

    Biofuels is currently driving the interest in bioenergy sector. The recently issued Renewable Energy Directive (2009/28/EC) confirms the 10% target, set by the EC, for energy from renewable sources in transport. The European Union is the largest producer of biodiesel in the world and biodiesel is also the most important biofuel used in the EU. The aim of this paper is to investigate the biomass ...

  • 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 ...

  • 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, ...

  • Production of biodiesel from pentaclethra macrophylla seed oil

    In the present work, the potentials of pentaclethra macrophylla (Africa oil bean) seed oil (PMSO) are evaluated for the first time as a feedstock for biodiesel. Methyl (PMFAME) and ethyl (PMFAEE) esters of PMSO were produced by standard transesterification procedure using potassium hydroxide (KOH) as catalyst and their qualities determined. Gas chromatography mass spectrometry (GCMS) runs of the ...
