Abstract (en)

[origin: US4421604A] The quality of coke is improved by measuring the width of a plastic zone of a given type of coal, comparing said measured zone with a predetermined zone width known to result in good quality coke, adjusting certain characteristics of said given coal prior to charging it into the coke oven to cause a change in said zone width of the coal that will ultimately result in improved coke quality. Typical adjusting steps include preheating the coal and/or the addition of coal binders, such as, various carbon and petro-based binding agents, for example, pitch.
