Kinetic Study and Modelling of n-Heptane Reforming Process over Pt/Zr-HMS/HZSM-5 Composite Catalysts

Pt/Zr(x)-HMS/HZSM-5 catalysts with various Si/Zr ratios (as x) were used for investigation of the kinetics of n-heptane reforming process under 350 - 450 oC reaction temperature, 35 to 80 ml min-1 flowing rate of hydrogen and 2 to 5 ml h-1 flowing rate of n-heptane. In the present work, two kinetics (power law and Langmuir - Hinshelwood) models were selected and examined to describe the kinetic...

First experimental ( n , γ ) cross sections of heavy p - process nuclei

First experimental (n, γ) cross sections of heavy p-process nuclei. First measurements of the stellar neutron capture cross sections are reported for the stable p isotopes 168 Yb, 184 Os, and 196 Hg. For 180 W and 190 Pt the uncertainties of 11% and 27% from previous measurements could be significantly reduced. Neutrons were produced at the Karls-ruhe 3.7 MV Van de Graaff Accelerator via the 7 ...

Inverse Kinematic Study of the (26g)Al(d,p)(27)Al Reaction and Implications for Destruction of (26)Al in Wolf-Rayet and Asymptotic Giant Branch Stars.

In Wolf-Rayet and asymptotic giant branch (AGB) stars, the (26g)Al(p,γ)(27)Si reaction is expected to govern the destruction of the cosmic γ-ray emitting nucleus (26)Al. The rate of this reaction, however, is highly uncertain due to the unknown properties of key resonances in the temperature regime of hydrogen burning. We present a high-resolution inverse kinematic study of the (26g)Al(d,p)(27)...

Compositional Dependent Amorphization in Zr Alloy Films by Means of Ni-Implantation

Ni-implantation has been conducted for sputter deposited Zr alloy films to investigate compositional dependent amorphization behavior in proportion to Ni in Zr alloys. As-deposited Zr and Zr–Cu with thickness of 200 nm shows columnar hcp-Zr and nano-crystalline hcp-Zr(Cu), respectively. Implantation of 150 keV Niþ with the amount of 1 10 ions/cm induces amorphization of Zr and Zr(Cu) with 100 n...

l - ex / 0 60 20 12 v 1 9 F eb 2 00 6 First measurement of the 14 N ( p , γ ) 15 O cross section down to 70 keV

In stars with temperatures above 20·10 K, hydrogen burning is dominated by the CNO cycle. Its rate is determined by the slowest process, the N(p,γ)O reaction. Deep underground in Italy’s Gran Sasso laboratory, at the LUNA 400 kV accelerator, the cross section of this reaction has been measured at energies much lower than ever achieved before. Using a windowless gas target and a 4π BGO summing d...

Experimental study of the 14N(p,gamma)15O reaction at energies far below the Coulomb barrier

At stellar temperatures, the N(p,γ)O reaction is the slowest of the carbon-nitrogenoxygen (CNO) cycle of thermonuclear reactions. The CNO cycle burns hydrogen into helium and dominates energy production at some point in the lifetime of most stars. The objective of the present work is to improve our knowledge of the CNO cycle by making a precise measurement of the N(p,γ)O reaction cross section ...
