Small lumps of coal are contacted in an upflow confined reactor with liquid SO2 and some recycled hydrocarbons at an elevated pressure to effect the disintegration of the coal to micro-sized dust particles and, preferably, the resulting coal dust and liquid SO2 with entrained liquid hydrocarbons that are withdrawn from the top of the reactor will undergo a further pressurized centrifugal contact-separation step. The liquid stream from the latter is recycled to the upflow reactor while the coal dust is recovered for use as a carbonaceous fuel ready for economical pipeline transportation suspended in either gas or liquid, with the liquid being either water or oil. Alternatively, the dust may be subjected to liquification, or such other treatment as may be desired.
