Practical data are presented regarding coal extraction and enrichment. Water flow rates for jigging are recommended. The additional secondary slurry formed is expressed as a function of the depth of coal enrichment. The quantity of additional slurry in the ≤0.5 mm class that is formed in the...
Mathematical models are developed for predicting the yield of coking byproducts on the basis of elementary and petrographic analysis of the coal batch.
The effectiveness of stabilization ($/t of hot metal) is assessed for ten coke samples. A method of comparing coke quality is proposed, on the basis of its influence on the coke consumption in hot-metal production. Three formulas for the dependence of the coke consumption on its quality are...
To solve the energy-saving and emission-reduction problem which caused by the deterioration of the thermal properties of coke in blast furnace and to improve the technologies applied to the inhibition to coke deterioration, benzene pyrolysis carbons were used to infiltrate into coke to inhibit...
Rotary-drum technology for semicoke production from Shubarkol’sk long-flame coal is outlined. The properties of semicoke for use as a reducing agent in ferroalloy production are presented.
The activity of CR-31 aluminum-oxide catalyst (La Roche Chemicals) over a period of 6.5 years (2000–2007) in the Claus reactor of byproduct-trapping shop 2 is monitored within the coke plant at OAO Magnitogorskii Metallurgicheskii Kombinat. The rate and extent of irreversible deactivation of the...
The separation of high-purity phenanthrene and anthracene from mixtures obtained in the rectification of the first anthracene fraction from coal tar is considered. The method employed is selective deposition from an aqueous solution of the anthracene-phenanthrene mixture with organic solvent.
Research on extractive applications of cyclohexanone is reviewed.
