Coal may be regarded as an organic–mineral complex formed by the accumulation of sediments and their metamorphic transformation to sedimentary rock. On that basis, Kuznetsk Basin coal may be analyzed in terms of the corresponding genetic characteristics of gelification and reduction and the...
The ignition temperature of three-component mixtures is determined. The mixtures contain coal of different metamorphic development, in various proportions. It is found that the actual ignition temperature differs from the values calculated on the basis of the sum rule; the actual ignition...
The pore structure of coal samples at different metamorphic stages (D, DG, GZhO, Zh, K, KS, and OS coal) is studied by the low-temperature adsorption of nitrogen, mercury porosimetry, and measurements of the actual density. On that basis, the quantity of closed pores in the samples is estimated....
The properties of coal concentrates are determined: the technical analysis, clinkering properties, petrographic and elementary analysis, and the product yields in coking. Structural characteristics of the coal’s organic mass are also calculated. The results obtained for Kuznetsk Basin coal are...
X-ray diffraction is a widely used nondestructive method of studying carbon materials. It is employed to study the phase composition of samples, to analyze the qualitative and quantitative composition of specific phases, and to assess the structural characteristics of crystalline carbon...
For the example of 80 organic solvents, the methods developed by the All-Russian Research Institute for Fire Protection (ARIFP) and the Dutch ME-TNO method for vapor cloud explosions (VCE) in enclosed spaces are compared. The comparison focuses on the safe volume of the building. The correlation...
