Evaluating the mechanical properties of laboratory coke on the basis of the expansion-pressure dynamics of coal and coal mixtures

Evaluating the mechanical properties of laboratory coke on the basis of the expansion-pressure... The production of coke with the specified mechanical properties mainly depends on the thermal destruction and clinkering of the coals in the plastic state. The properties of the plastic coal mass (viscosity, gas permeability, plastic-layer thickness, and temperature range of the plastic state) play a significant role in producing coke of specified quality [1–4]. This is because the porous structure of semicoke that will be converted to coke on subsequent heating is formed in the plastic state. Hence, other conditions being equal, the properties of coal in the plastic state may be used to evaluate coke quality (its mechanical strength). http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Coke and Chemistry Springer Journals

Abstract

The production of coke with the specified mechanical properties mainly depends on the thermal destruction and clinkering of the coals in the plastic state. The properties of the plastic coal mass (viscosity, gas permeability, plastic-layer thickness, and temperature range of the plastic state) play a significant role in producing coke of specified quality [1–4]. This is because the porous structure of semicoke that will be converted to coke on subsequent heating is formed in the plastic state. Hence, other conditions being equal, the properties of coal in the plastic state may be used to evaluate coke quality (its mechanical strength).
