At the blast furnace of PJSC “Magnitogorsk Metallurgical Plant” (MMK), specific consumption coke was reduced by impact on thermal reverse zone (TRZ) increasing natural gas above 120 m 3 /t cast iron under conditions increased reactivity and hot strength coke. In first pair periods, an increase in CRI from 38.4 to 39.3 % with a decrease CSR 36.3 34.6 accompanied ratio total oxygen entering 0.43 ...

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 ...
