1. A multi-modal bed of coking material comprising:
a first particulate coking material having a first bulk density; and
a second particulate coking material having a second bulk density less than the first bulk density,
the first particulate coking material being distributed with the second particulate coking material such that the multi-modal bed of coking material comprises a generally uniform distribution of the first particulate material and the second particulate material from a bottom portion of the multi-modal bed of material to an upper portion of the multi-modal bed of material, wherein the multi-modal bed of material includes a third density higher than an ideal bulk density based on (i) a weight fraction of the first particulate material and the first bulk density and (ii) a weight fraction of the second particulate material and the second bulk density,
wherein—
the first particulate coking material comprises a carbon containing material and the second particulate coking material comprises breeze having an ash content between 15-40%,
in operation, when the first particulate coking material is processed in a coke oven, the first particulate produces a first coke product having a first CSR, and
in operation, when the multi-modal bed of material is processed in a coke oven, the multi-modal bed of material produces a second coke product having a second CSR (i) of 58 or greater and (ii) no more than 10% less than the first CSR.
