NREL Updates Cetane Data Used for Development of Energy Efficient Fuels and Engines

10.09.2014

The Energy Department’s National Renewable Energy Laboratory (NREL) has released a long-anticipated update to the source-of-record for cetane number data. This information is vital to the development of new, energy-efficient, low-carbon fuels and compatible engines.

Researchers, as well as members of the engine, vehicle, and fuel industries, rely on these numbers to target compounds for development of new fuels capable of greater energy efficiency, cleaner emissions, and maximum performance in diesel engines.

A cetane number is a relative ranking of fuels based on the amount of time between fuel injection and ignition (ignition delay) in a diesel engine. A minimum cetane number is specified in the ASTM standard that defines the quality of diesel fuel sold in the United States.

The recently published Compendium of Experimental Cetane Numbers compiles cetane number data from 62 sources for readers to use in selecting potential compounds and formulas for development of models, tools, and fuels.

In addition to updating information, the new edition provides additional measurements on a larger number of compounds, along with assessment of data quality.

The updated report includes all available single-compound cetane number data found in the scientific literature published prior to March 2014, including:

  • Information on 389 pure compounds

  • 584 measurements, including more than 250 new measurements

  • Expanded discussion of the accuracy and precision of the methods most commonly used for determining cetane numbers

  • Extensive annotation allowing readers to judge the relative reliability of individual results.

“The original report has been cited more than 130 times,” NREL Principal Engineer Robert McCormick said. “We expect that the new edition will continue be used extensively to develop models, target compounds for new fuels, and tools to help predict cetane numbers in the future.”

NREL is the U.S. Department of Energy's primary national laboratory for renewable energy and energy efficiency research and development. NREL is operated for the Energy Department by The Alliance for Sustainable Energy, LLC.

Im Focus: Better thermal conductivity by adjusting the arrangement of atoms

Adjusting the thermal conductivity of materials is one of the challenges nanoscience is currently facing. Together with colleagues from the Netherlands and Spain, researchers from the University of Basel have shown that the atomic vibrations that determine heat generation in nanowires can be controlled through the arrangement of atoms alone. The scientists will publish the results shortly in the journal Nano Letters.

In the electronics and computer industry, components are becoming ever smaller and more powerful. However, there are problems with the heat generation. It is...

Im Focus: First-ever visualizations of electrical gating effects on electronic structure

Scientists have visualised the electronic structure in a microelectronic device for the first time, opening up opportunities for finely-tuned high performance electronic devices.

Physicists from the University of Warwick and the University of Washington have developed a technique to measure the energy and momentum of electrons in...

Im Focus: Megakaryocytes act as „bouncers“ restraining cell migration in the bone marrow

Scientists at the University Würzburg and University Hospital of Würzburg found that megakaryocytes act as “bouncers” and thus modulate bone marrow niche properties and cell migration dynamics. The study was published in July in the Journal “Haematologica”.

Hematopoiesis is the process of forming blood cells, which occurs predominantly in the bone marrow. The bone marrow produces all types of blood cells: red...

Im Focus: Artificial neural network resolves puzzles from condensed matter physics: Which is the perfect quantum theory?

For some phenomena in quantum many-body physics several competing theories exist. But which of them describes a quantum phenomenon best? A team of researchers from the Technical University of Munich (TUM) and Harvard University in the United States has now successfully deployed artificial neural networks for image analysis of quantum systems.

Is that a dog or a cat? Such a classification is a prime example of machine learning: artificial neural networks can be trained to analyze images by looking...

Im Focus: Extremely hard yet metallically conductive: Bayreuth researchers develop novel material with high-tech prospects

An international research group led by scientists from the University of Bayreuth has produced a previously unknown material: Rhenium nitride pernitride. Thanks to combining properties that were previously considered incompatible, it looks set to become highly attractive for technological applications. Indeed, it is a super-hard metallic conductor that can withstand extremely high pressures like a diamond. A process now developed in Bayreuth opens up the possibility of producing rhenium nitride pernitride and other technologically interesting materials in sufficiently large quantity for their properties characterisation. The new findings are presented in "Nature Communications".

The possibility of finding a compound that was metallically conductive, super-hard, and ultra-incompressible was long considered unlikely in science. It was...
