suppression of coke formation in thermal cracking by coke inhibitors
the main purpose of this research was to:1.develop a coking model for thermal cracking of naphtha.2.study coke inhibition methods using different coke inhibitors.developing a coking model in naphtha cracking reactors requires a suitable model of the thermal cracking reactor based on a reliable kinetic model.to obtain reliable results all these models shall be solved simultaneously.for this pu...
15 صفحه اولVibrational coherence of I2 in solid Kr.
Time-resolved coherent anti-Stokes Raman scattering, with a resolution of 20 fs, is used to prepare a broadband vibrational superposition on the ground electronic state of I2 isolated in solid Kr. The coherent evolution of a packet consisting of nu=1-6 is monitored for as many as 1000 periods, allowing a precise analysis of the material response and radiation coherence. The molecular vibrations...
متن کاملSize Evolution Study of the Electronic and Magnetic Properties of MgO Nanoclusters
Magnesium oxide nanoclusters have attracted much attention due to their potential applications to catalysis and novel optoelectronic materials. In the present study, we have studied the electronic and magnetic properties of the stoichiometric magnesium oxide nanoclusters (MgO)n for n = 2-20. Although the binding energy increases with the size of the cluster, it re...
متن کاملsimulation and experimental studies for prediction mineral scale formation in oil field during mixing of injection and formation water
abstract: mineral scaling in oil and gas production equipment is one of the most important problem that occurs while water injection and it has been recognized to be a major operational problem. the incompatibility between injected and formation waters may result in inorganic scale precipitation in the equipment and reservoir and then reduction of oil production rate and water injection rate. ...
Exciton-induced desorption and surface-type luminescence of Kr atoms from Kr-doped solid Ar
Selective exotat~on of Kr atoms at the surface of sohd Ar with synchrotron radlatton stimulates the desorptlon of excited Kr atoms (e g., Kr3P1) as well as the luminescence of Kr-type surface centers at hv = 9 998 eV (3P 1) and at hv = 9.881 eV (3P 2) The high-resolution luminescence spectra and the yield curves of the radiative decay channels have been measured. They are interpreted taking int...
