30. Pyrolysis of Fuels in a Micro-Reactor: Radical/Radical Reactions Make PAHs

Prof. Barney Ellison (University of Colorado)

To understand the thermal decomposition mechanisms of fuels, we are developing a tiny flow tube to study the thermal cracking of complex organic molecules. We use a heated 1 mm × 2 cm SiC microtubular reactor to decompose complex fuels. Thermal decomposition of 0.1 % samples mixed with He or Ar carrier gases takes place at pressures of 75 — 250 Torr and at temperatures up to 1700 K. Residence...

35. Probing High Tmeperature and Pressure Reactions and Gas States with VUV and X-rays

Dr Robert Tranter (Argonne National Laboratory)

Synchrotron light sources offer many opportunities for probing chemical and physical properties. For example, VUV-photoionization mass spectrometry gives detailed insights into the reactions of transient species of importance to atmospheric chemistry and combustion. At much higher photon energies ex-situ and in-situ, X-ray scattering experiments examine particle formation within flames. In...

1. Kinetics and isomeric/isobaric product analysis of radical reactions in flow tube investigated by VUV photoionization mass spectrometry

Dr Xiaofeng Tang (Hefei Institutes of Physical Science, Chinese Academy of Sciences)

10/01/2019, 16:10

Photoionization mass spectrometry (PIMS) as a powerful method has been widely utilized and provided valuable insight in the field of gas-phase reactions. We present here a vacuum ultraviolet (VUV) photoionization orthogonal time-of-flight mass spectrometer (TOFMS) coupled with a microwave discharge generator and a fast flow tube reactor to study radical reactions of atmospheric and combustion...

Gas phase spectroscopy offers the unique advantage of accessing intrinsic properties in the absence of solvent, and ultimately provides a mean to test theoretical methods. Biomolecules and large assemblies are fragile and difficult to place in the gas phase intact and studies are usually limited to building blocks and small oligomers.
Modern ionization techniques, such as electrospray...
