The operational efficiency of the batch-preparation shop is assessed, in terms of the uniformity of batch quality. The importance of batch uniformity in the production of blast-furnace coal of stable quality is confirmed. Analysis of individual stages of coal preparation permits the development...
The petrographic characteristics of bed samples of gas coal from different locations in the Kuznetsk Basin are studied. Analysis of reflection patterns permits identification of the petrographic features affecting the behavior of coal in high-temperature coking. Additional assessment of the...
The industrial production of blast-furnace coke of improved quality has been organized at Makeevka Coke Plant. The coke produced meets global quality standards.
Means of improving the electrode pitch in processing coal tar obtained by light pyrolysis have been developed on the basis of operational experience at Makeevka Coke Plant.
The sorption of Mn2+ ions from aqueous solutions of humic acids derived from Tisul’sk lignite is investigated. The influence of treatment of the humic acids by hydrogen peroxide on their sorptional characteristics is considered. The sorptional capacity of modified and unmodified humic acids for...
In order to improve the yield of liquid fraction and phenolics content during lignin pyrolysis, an effective method of lignin pyrolysis through the pretreatment of lignin by an acidic ionic liquid 1-butyl-3- methyl-imidazolium dihydrogen phosphate ([Bmim]H2PO4) at low temperature is investigated...
