1. A process for the production of coke and one or more volatile products, 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 mass % and a water content of less than around 5 mass %;
(ii) combining the PCP with a liquid residue oil in order to create a combined solid-liquid blend, wherein the solid-liquid blend comprises at least around 0.1 mass % and at most around 30 mass % PCP;
(iii) subjecting the solid-liquid blend to a temperature in excess of 375° C. for a time period sufficient to induce cracking of at least 1% of the PCP particles to generate the one or more volatile products, and
(iv) producing coke from the product of step (iii),
wherein the liquid residue oil comprises one or more of the group consisting of: residue from refinery atmospheric distillation of crude oil feedstock; residue from vacuum distillation of crude oil feedstock; slurry oil from catalytic crackers; bottoms from naphtha crackers; oil produced by pyrolysis of plastic, wood and biomass; black liquor from the Kraft process of wood pulp manufacture; light and heavy cycle oil; light and heavy gas oil; diesel fuel; fuel oil; bunker oil; boiler fuel oil; decanted oil; marine fuel oil; marine diesel oil; biodiesel; slop oil; and oil from biofuel manufacture.
