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 اولElectroacoustic analysis of an electret loudspeaker using combined finite-element and lumped-parameter models.
An unconventional type of electrostatic loudspeaker is presented in this paper. The loudspeaker made of thin, light, and flexible electret material lends itself well to the space-concerned applications. Electrical impedance measurement reveals that the coupling between the electrical system and the mechanical system is weak, which renders conventional parameter identification based on electrica...
متن کاملMicrophones and Measurements
This paper presents the current status of an ongoing investigation of differences in formant estimates of vowels that may come about solely due to the circumstances of the recording of the speech material. The impact of the interplay between type and placement of microphone and room acoustics are to be examined for adult males and females across a number of vowel qualities. Furthermore, two est...
متن کاملThe Photocatalytic, Thermal Degradation Kinetics and Lifetime Prediction of Some Commercial Reactive Dyes
The photocatalytic degradation of the commercial reactive Black5 (RB5), Blue19 (RB19), Green19 (RG19), Red120 (RR120), and Yellow81 (RY81) in aqueous solution and sunlight were examined in the presence of Fe2O3 and the mixture Fe2O3/H2O2 as catalysts. The results showed that the photocatalytic degradation followed first-order...
متن کاملThermal Analysis of Turbocharger Steel Gasket via Experimental Test
Increasing the power (torque) of nowadays engines, along with reduction of fuel consumption and dimensions of them, cause to the use of turbocharged systems. Since turbo chargers are exposed to the exhaust hot gases and have a high operating speed, it is necessary to utilize high technology design and special materials with high cost. The temperature of the exhaust system with gasoline fuel som...
