A process comprising heating coal in a substantially air-free environment to liberate volatile materials and produce coke, condensing at least some of the volatile materials so liberated to liquefied products and dispersing the coke therein to form a coke slurry, feeding the coke slurry to a slurry

A process comprising heating coal in a substantially air-free environment to liberate volatile materials and produce coke, condensing at least some of the volatile materials so liberated to liquefied products and dispersing the coke therein to form a coke slurry, feeding the coke slurry to a slurry pipeline, and pumping the coke slurry through the pipeline to a destination. Apparatus comprising a tube furnace having an external heating means for indirectly heating powdered coal therein in a substantially air-free environment to a temperature adequate to liberate volatile materials and produce coke, means to feed powdered coal to the furnace under pressure and force the volatile materials and coke produced in the furnace through the furnace to a condensing means in which at least some of the volatile materials are condensed with the coke dispersed therein to form a coke slurry, and means to convey the coke slurry from the condensing means to a pipeline for transport to a destination.
