The porous structure of natural coal samples from the Usinsk deposit in the Pechora Coal Basin was studied using the low-temperature adsorption of nitrogen, mercury porosimetry, and scanning electron microscopy. Considerable differences in the characteristics of the porous structures of coals obtained by the low-temperature adsorption of nitrogen and mercury porosimetry were found. These differences are indicative of the presence of closed pores in all of the test samples of coals. The quantitative and component compositions of coal gases were determined by methods based on a combination of gas-liquid and gas-adsorption chromatography. © 2014 Allerton Press, Inc.

The aluminosilicate microspheres from the fly ash of different power stations (Western Siberian TETs, Belovskaya GRES, Novo-Kemerovo TETs, and Tom-Usinskaya GRES), which burn Kuznetsk coal, were studied by a set of physicochemical methods (BET, SEM, XRD analysis, and granulometric analysis). For comparison, a sample of microspheres from the Pavlodar TETs-2, which burns Ekibastuz coal, was examined. Differences in the textural, structural, and morphological properties of microspheres, which are related to the nature of burnt coal and the operating conditions of combustion, were demonstrated. © 2015, Allerton Press, Inc.

The granulometric composition of the powders of GZhO, OS, and G coals was measured by a laser diffraction method upon the dispersion of samples in an aqueous medium with the addition of a Dusazin 901 surfactant (Fritsch, Germany). The metrological evaluation of the results of determinations by coal-sizing analysis and the laser diffraction method was performed. It was shown that satisfactory results were obtained for the samples of GZhO and G coals in all of the determination ranges. For the samples of OS coal, the limit of reproducibility between the two methods in ranges of 0.074 + 0 and –0.20 + 0.10 mm was exceeded by factors of 1.5 and 1.2, respectively. © 2016, Allerton Press, Inc.

The content of polycyclic aromatic compounds-including the strong carcinogens benz[a]pyrene and dibenz[a,h]anthracene-in coke-plant wastewater is investigated. Biochemical purification permits the removal of the following polycyclic aromatic compounds: naphthalene, acenaphthylene, fluorene, acenaphthene, phenanthrene, anthracene, fluoranthene, pyrene, and benz[k]fluoranthene (79.6-99.9% removal); and benz[a]pyrene (65.7% removal). By contrast, biochemical treatment increases the content of the following compounds in the wastewater: benz[b]fluoranthene, benz[g,h,i]perylene, and indeno[1,2,3-cd]pyrene. © 2010 Allerton Press, Inc.

Analysis of the physicochemical properties, chemical compensation, and volume of condensates and deposits of metallurgical gases-coke-oven gas, blast-furnace gas, and converter gas-shows that metal-lurgical-gas condensates account for 10. 8% of the total coke-plant wastewater. The metal content in the condensates does not exceed the limits on the metal content in wastewater sent for biochemical treatment and will not harm the purification system. © 2010 Allerton Press, Inc.
