1. A process for the production of anisotropic coke, the process comprising the steps of:
(i) providing a purified coal product (PCP), wherein the PCP is in particulate form, and wherein at least about 90% by volume (% v) of the particles are no greater than about 100 μm in diameter; wherein the PCP has an ash content of less than about 10% by mass (% m) and a water content of less than around 5% m;
(ii) combining the PCP with a feedstock oil in order to create a combined solid-liquid blend, wherein the solid-liquid blend comprises at least around 0.1% m and at most around 50% m PCP;
(iii) pyrolyzing the solid-liquid blend at a temperature in excess of 400° C. for a time period sufficient to induce formation of mesophase in the solid-liquid blend and form a pyrolyzed solid-liquid blend product, and
(iv) utilizing the pyrolyzed solid-liquid blend product from step (iii) as a feedstock in a delayed coker to thereby produce an anisotropic coke product.
