• Kinetic modeling for steam reforming of naphtha surrogates on NiMgAl catalyst. The model discrimination was conducted based artificial neural networks. Ab initio (DFT) calculations allow further refinements and corroborations. selected kinetic satisfactorily captures catalyst activity selectivity. validated a wider set operating conditions feedstocks. Steam hydrocarbons is will be, in the sho...

The series of mono-metallic and bi-metallic catalysts have been prepared by impregnatingwith solutions containing compound of H2PtC15,NbC15 and lml HC1 (0.1 mol). The activityand selectivity of the catalysts have been determined under conditions at 450-500°C, 15-30atm. Molar ratio H2/C7H16=5 and VVH=1.5/h for converting n-heptane. Under theseexperimental conditions it has been established that ...

Catalyitic reforming is one of the refinery processes in catalyst conversion that results to anincreases in octane number of naphtan which leads to production of gasoline with higher octanenumber. Hydrocarbons with high octan number that are produced in reforming process are as;aromatics, paraffins, isomers and etc.Not only Aromatics are used as fuel for motors but they are also useful in petro...

Scratch-induced cracking is a serious problem for the use of glass products. At the scratch process, both median (vertical to the glass surface) and lateral (horizontal to the glass surface) cracks are formed. In this study, morphology of the scratch-induced cracks in a commercial soda-lime-silica glass was investigated by the scanning electron microscopy for the specimen broken across the scra...

For many years, commercial-grade hexane has been the preferred solvent for extracting oil from cottonseed. Recent environmental and health concerns about hexane may limit the use of this solvent; therefore, the need for a replacement solvent has become an important issue. Heptane is similar to hexane, but does not have the environmental and health concerns associated with the latter. On a labor...

The droplet burning characteristics of binary blends of iso-octane, n-heptane and toluene were studied in an ambience that minimizes external convection and promotes spherical droplet flames. The results are compare...

The chemical kinetics of n-heptane (n-C 7 H 16 ) – an important reference compound for real fuels – oxidation are well studied at stoichiometric and lean conditions. However, there is only limited information on the n-heptane chemical kinetics in fuel-rich combustion. In order to verify the accuracy of chemical kinetic models at these conditions, the oxidation of rich n-heptane mixtures has bee...
