Ranking and comparing of traditional and industrial coke making by TOPSIS technique in Shahrood Simin Coke Company

Various traditional and industrial coke making techniques were discussed based on their limitations and production capacities, and the criteria such as the quality and size of coke production, amount of coke crumb, amount of investment, amount of operational costs, labor force and mechanization. In this work, the rankings of various traditional and industrial coke making techniques were carried...

‏‎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...

investigation of coke deposition and coke inhibition by organosul-fur compounds in the pyrolysis of naphtha in the get stirred reactor system

Regeneration 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...

2007: Graphite Electrode and Needle Coke Development

The booming Asian economies are driving the recent increase in steel production. Although BOF steel production growth is much stronger than EAF, the outlook for EAF is promising due to increasing substitution of steel scrap by DRI and pig iron, as well as an increase in electrical energy supply in China. The favorable operational reliability of AC-furnaces is the reason that most new furnace pr...
