Theoretical principles are outlined for the development of direct methods of determining the clinkering properties of rammed coal and coal batch. The strength variation of semicoke samples obtained on clinkering various coals with inert filler is considered.
The first step is kinetic study of the drying and pyrolysis of lignite particles in the range 700–900 ° C, which is characteristic of coal gasification in an autothermal reactor with an inverse thermal wave. Analysis of the experimental data yields a linear kinetic equation for the mass loss of...
Studies on hazardous metals pollution through various processes of utilization of the Assam (India) coals suffer from the lack of reliable information on the level of trace and heavy metals in them. Four representative coal samples with high sulphur from Ledo, Tikak, Tipong and Baragolai...
Papers presented at the Fifteenth Annual Seminar of Coke and Refractory Specialists are reviewed; the seminar was held in 2008 at OAO Dinur (Pervouralsk, Sverdlovsk Oblast).
In the following article the results of installation and exploitation of the thermal coal charge pretreatment plant at OJSC “Yasinovsky Coke and Chemical Plant” are introduced. The results of coking of different variants of thermally pretreated coal charges are also provided. An issue concerning...
The influence of various technological factors on the high-temperature properties of coke is investigated. It is found that factors facilitating an orderly organic structure of the coke (fine grinding and compaction of the batch, increased conditioning of the coke, dry slaking, the introduction...
The molecular interactions in binary systems consisting of water and organic solvent are considered. The use of water with organic solvents in the extraction and purification of organic materials in the coke, oil, and chemical industries is reviewed, in Russia and elsewhere.
