The distribution and quality of Russian coal and coke resources are compared for periods before (the first nine months of 2008) and during (from the fourth quarter of 2008 to the second quarter of 2009) the economic crisis. Attention then turns to the definition and determination of the...
A recent patent regarding the preparation and composition of coal batch is analyzed.
Difference spectra obtained after subtraction of the model spectrum for the organic mass are used to analyze the ash content of coal-mineral mixtures by DRIFT spectroscopy in the intermediate IR range. For quantitative determination of the ash content, calibration is based on projection onto...
Iron compounds encountered in coal deposits are considered, along with their influence on the applicability of such coal.
Industrial coking data indicate that, given the scarcity of Zh and K coal, GZh coal from Raspadskaya enrichment facility may be used as the clinkering component in coking batch. To obtain blast-furnace coke of satisfactory quality, the content of Zh or K coal in the batch may be no less than 10%...
A method is proposed for assessing the environmental and thermal characteristics of coke oven batteries and is tested for coke oven batteries 1 and 5 at OAO Zaporozhkoks. On the basis of data for the environmental and thermal value of the coke oven batteries, their operation is analyzed, and...
A literature review focuses on the complex formation of diatomic phenols, their solubility in organic solvents, and their extraction from the thermal-processing products of coal by extraction, crystallization and rectification.
Environmental-protection measures reduce pollutant emissions to the atmosphere and so reduce the plant’s environmental impact in the region.
