Dimensional Changes of Molecularly Oriented Domains in Coke

The following characteristics of molecularly oriented coke domains are investigated as a function of their position within the coke and the distance from the coke oven’s heating wall: their height L c and width L a , the interplane distance d 002 , the domain density ρ, and the number of layers N within the domain. It is found that L c and L a decrease nonlinearly with increase in the distance from the coke oven’s heating wall. The coke’s structural strength Π c (State Standard GOST 9521–2017) is greater for positions near the wall than for the central region of the coke. The ash content and chemical composition of coke samples in the >0.1 mm and
