To determine the relation between the expansion pressure and the genetic and technological properties of coals, measurements of the expansion pressure are made during the coking of coal samples in a 1-kg laboratory furnace. No relation is found between the expansion pressure and the genetic and...
In the initial stages of coalification, there is no dehydrogenation, and therefore the organic mass of coal cannot be the source of hydrogen for methane formation. It is possible that an explosive mixture of methane and oxygen may be formed from carbon dioxide and moisture in the coal bed as a...
Papers regarding Russia’s coke furnaces—in particular, their construction and reconstruction and issues of preservation and operational stability—presented at the Seventeenth Annual Seminar of Coke-Industry Specialists are summarized. The seminar was hosted by OOO EvrazKoksSibir’, a subdivision...
The possibility of producing pitch coke from moderate-temperature pitch with the introduction of 10–30% dusty carbon fillers is investigated. The influence of graphitized dust and coal dust on the yield and quality of pitch coke is demonstrated.
The benefits of coke-briquet production are outlined. The characteristics of the briquets are noted. The results of their use as fuel in cupola smelting of iron are considered.
To improve distilled-naphthalene production, greater removal of phenols and bases from the naphthalene fraction is proposed. Continuous multistage extraction is used for this purpose, with the subsequent production of rectified naphthalene.
Introducing additives in BDUS 70/100 petroleum bitumen results in a high-quality binder for the preparation of floated asphalt with improved performance. Effective additives include amide waxes, natural waxes, high-molecular paraffins obtained from CO-hydrogen mixtures by the Fischer-Tropsch...
