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 اولDiscrete Element Method Modeling of the Rheological Properties of Coke/Pitch Mixtures
Rheological properties of pitch and pitch/coke mixtures at temperatures around 150 °C are of great interest for the carbon anode manufacturing process in the aluminum industry. In the present work, a cohesive viscoelastic contact model based on Burger's model is developed using the discrete element method (DEM) on the YADE, the open-source DEM software. A dynamic shear rheometer (DSR) is used t...
متن کاملUpgrading Delayed Petroleum Coke Fines by the Use of Pitch Binders
Syrian petroleum coke, produced by a delayed coking unit, is characterized by a high percentage of fines which tends to reduce its commercial value. Blending coke fines using appropriate binders, such as bitumen and polyacrylic acid, can lead, however, to an improved coke that is similar in structure, appearance and other properties to better-quality coke lumps. In this work, samples of Syrian ...
متن کاملidentifying provinces with competitive advantage in "manufacture of coke, refined petroleum products and nuclear fuels" sector
manufacture of coke, refined petroleum products and nuclear fuel is one of the isic (international standard industrial classification of all economic activities, rev.2) that produced 8.5 percent of industry value-added in iran in 2007. isfahan, tehran, khuzestan, hormozgan, and markazi provinces accounted for 90 percent of the value added in this sector. to determine competitive advantage in th...
متن کاملRegeneration performance and carbon consumption of semi-coke and activated coke for SO₂ and NO removal.
To decrease the operating cost of flue gas purification technologies based on carbon-based materials, the adsorption and regeneration performance of low-price semi-coke and activated coke were compared for SO2 and NO removal in a simulated flue gas. The functional groups of the two adsorbents before and after regeneration were characterized by a Fourier transform infrared (FTIR) spectrometer, a...
