An Experimental and Kinetic Modeling Study of N-dodecane Pyrolysis and Oxidation in a Flow Reactor

August 31, 2015

Author(s)

S. Banerjee, Rei Tangko, David Sheen, Hai Wang, Craig T. Bowman

N-dodecane (n-C12H26) is a straight chain alkane that forms an important constituent of surrogate blends for common aviation fuels such as JP8 and Jet-A. The current study investigates n-dodecane pyrolysis and oxidation kinetics in the intermediate

1H and 13C NMR Analysis of Gas Turbine Fuels As Applied to the Advanced Distillation Curve Method

July 30, 2015

Author(s)

Jessica L. Burger, Jason A. Widegren, Tara Lovestead, Thomas J. Bruno

The analysis of the gas turbine fuels by 1H and 13C nuclear magnetic resonance (NMR) spectroscopy as applied to the composition explicit (or advanced) distillation curve method is reported. In order demonstrate the general applicability for such fuels

Kinetics of the Reactions of H and CH3 with n-Alkanes: Experiments with n-Butane and a Reevaluation Based on a Combustion Model Reaction Network Analysis

July 16, 2015

Author(s)

Jeffrey A. Manion, David A. Sheen, Iftikhar A. Awan

Presented is a combined experimental and modeling study of the kinetics of the reactions of H and CH3 with n-butane, a representative aliphatic fuel. Abstraction of H from n-alkane fuels creates alkyl radicals that rapidly decompose at high temperatures to

Flexible metal-organic framework compounds: In situ studies for selective CO2 capture

June 19, 2015

Author(s)

Andrew J. Allen, Laura Espinal, Winnie K. Wong-Ng, Wendy Queen, Craig Brown, Steven R. Kline, Kristi L. Kauffman, Jeffrey T. Culp

Results from in situ experiments are presented to correlate carbon capture with dynamic structural changes in two flexible metal-organic framework (MOF) materials: porous coordination polymers (PCPs) exhibiting promising carbon dioxide adsorption

Application of the Advanced Distillation Curve Method to Fuels for Advanced Combustion Engine Gasolines

June 9, 2015

Author(s)

Jessica L. Burger, Nico Schneider, Thomas J. Bruno

Abstract: Incremental but fundamental changes are currently being made to fuel composition and combustion strategies in order to diversify feed-stocks, decrease pollution, and increase efficiency. This rapid increase in parameter space makes it difficult

Interrogating the Carbon and Oxygen K-edge NEXAFS of a CO2-dosed Hyperbranched Aminosilica

December 19, 2014

Author(s)

Laura Espinal, Martin L. Green, Dean M. DeLongchamp, Watcharop Chaikittisilp, Jarod C. Horn, Miles Sakwa-Novak, Cherno Jaye, Daniel A. Fischer, Nicholas Brunelli, Christopher Jones

Near edge x-ray absorption fine structure (NEXAFS) spectroscopy was used to study the adsorption of CO2 in a hyperbranched aminosilica (HAS) compound, a porous solid state material with great potential for carbon capture applications. After dosing a

Evaluated Kinetics of Terminal and Non-Terminal Addition of H Atoms to 1-Alkenes: A Shock Tube Study of H + 1-Butene

December 17, 2014

Author(s)

Jeffrey A. Manion, Iftikhar A. Awan

Single-pulse shock tube methods have been used to thermally generate hydrogen atoms and investigate the kinetics of their addition reactions with 1-butene at temperatures of 880 K to 1120 K and pressures of 145 kPa to 245 kPa. Rate parameters for the

An Equation of State for the Thermodynamic Properties of Cyclohexane

December 5, 2014

Author(s)

Yong Zhou, Jun Liu, Steven Penoncello, Eric Lemmon

In this work, an equation of state for cyclohexane has been developed using the Helmholtz energy as the fundamental property with independent variables of density and temperature. Multi-property fitting technology was used to fit the equation of state that

Vapor-phase (p, , T, x) behavior and virial coefficients for the (methane + propane) system

November 12, 2014

Author(s)

Mark O. McLinden, Markus Richter

The (p, ρ, T, x) behavior of three (methane + propane) mixtures was measured with a two-sinker magnetic suspension densimeter over the temperature range of (248.15 to 373.15) K with pressures up to the lesser of the dew point pressure or 6 MPa. The

A thermodynamic investigation of the cellulose allomorphs: cellulose(am), cellulose I?(cr), cellulose II(cr), and cellulose III(cr)

November 11, 2014

Author(s)

Robert N. Goldberg, Jacob Schliesser, Ashutosh Mittal, Stephen R. Decker, Ana Filipa L. Santos, Vera L. Freitas, Aaron A. Urbas, Brian E. Lang, Christian Heisse, Maria D. Ribeiro da Silva, Brian F. Woodfield, Rui Katahira, Wei Wang, David K. Johnson

The thermochemistry of samples of amorphous cellulose, cellulose I, cellulose II, and cellulose III was studied by using oxygen bomb calorimetry, solution calorimetry in which the solvent was cadoxen, and with a Physical Property Measurement System (PPMS)

Direct and indirect measurements and modeling of methane emissions in Indianapolis, IN

October 13, 2014

Author(s)

Kuldeep R. Prasad

Abstract Based on recent EPA Greenhouse Gas Inventories, releases of methane (CH4) from the natural gas supply chain in the United States account for approximately 23% of the total US CH4 emissions. However, there continue to be questions regarding the

A perspective on the origin of lubricity in petroleum distillate motor fuels

September 15, 2014

Author(s)

Peter Y. Hsieh, Thomas J. Bruno

Lubricity, or a substance's effect on friction and wear between two surfaces in relative motion, is affected by both chemical and physical mechanisms present at a sliding contact. The inherent lubricity of distillate motor fuels stems from surface-active

Reference Correlation of the Viscosity of n-Heptane from the Triple Point to 600 K and up to 248 MPa

June 5, 2014

Author(s)

E.K. Michailidou, Marc J. Assael, Marcia L. Huber, Ilmutdin M. Abdulagatov, Richard A. Perkins

This paper contains new, representative reference equations for the viscosity of n-heptane. The equations are based in part upon a body of experimental data that has been critically assessed for internal consistency and for agreement with theory whenever
