  Unlike, other properties, coal loses its fluidity on weathering, i.e. oxidation in presence of air on long storage in the yard, and the fluidity value changes on blending with different coals.

Kovalik.   The complex relationships between coal thermoplastic behavior and resultant coke properties have been shown to be highly dependent on carbonization conditions, for example, an increase in heating rate and pressure increases the fluidity during the carbonization of this relatively low-rank : M.L. Chan, Ck. Man, J.W. Patrick, K.M. Thomas. The evolution of gaseous oxygen-containing species (CO, CO2, and H2O) during carbonization of 10 types of caking coals has been investigated mainly using a fixed-bed quartz reactor to reveal the influence of inherent oxygen species on the Gieseler fluidity of the coal particles. The heating rate and temperature were 3 °C/min and °C, respectively.

The heating rate and temperature were 3 °C/min and °C, respectively. The hard coking coals having good fluidity, which yield good coke, however are not only very expensive, but also are limited in reserves.

Introduction. Coal behavior during carbonization is of wide interest for cokemaking industry due to its close relationship to the technical problems being associated with conducting the process and the quality of final product [1,2].These include mainly, on the one hand, the demand for heat that needs to be provided for the process, as well as the rate of heating, which stems from the. This book is an integrated approach towards the applications of coal (organic) petrology and discusses the role of this science in the field of coal and coal-related topics. Coal petrology needs to be seen as a continuum of organic (macerals) and inorganic (minerals and trace elements) contributions to the total coal structure, with the.
