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...

Coke strength is the most important characteristic for retaining permeability in the bed of a blast furnace. In the present study, coke was coated with phenolic resin in order to improve the coke strength, and a nanoindentation method was used to estimate the strength of the coated coke after reaction under CO2 atmosphere. The elastic modulus was measured for the microporous coke substrate,. Th...

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...

the kinetics of catalyst deactivation and coke formation during dehydrogenation of propane over supported pt–based catalysts and, in particular, the effect of alkali metal promoters on catalyst activity and stability were studied. the analysis of propane conversion data showed that there is an optimum level of alkali metal promoter loading for both catalyst activity and stability.a model based ...

PURPOSE Despite the presence or absence of artificial sweeteners in cola drinks, both regular and diet soft drinks still contain phosphoric and citric acid, which contributes to the total acidic challenge potential on enamel. The purpose of this study was to assess the plaque pH, in vivo, after a substrate challenge of diet and regular soft drinks. METHODS Seventeen subjects were recruited fo...

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 ...

Production of iron through BF route is still a dominant route and coke is a major raw material and energy source for the blast furnaces. The process of coal carbonization in slot ovens is one of the major sources of atmospheric pollution in an Integrated Steel Plant. Coke making process involves coal preparation, carbonization and coke handling operations. To meet the demand of Blast Furnaces o...

The calcined petroleum cokes are used in production of aluminum anode-grade, graphite electrode, needle-grade, titanium dioxide pigments. Petroleum coke (green and calcined) is produced by the high pressure thermal decomposition of heavy petroleum process streams and residues. Green coke undergoes additional thermal processing to produce calcined coke. Various properties of calcined cokes from ...
