Carbonization of coal
Patent
·
OSTI ID:7010651
This patent describes a process for the carbonization of a fusible coal containing volatilizable constituents with the production of dry solid powdered coke and recovery of said volatilizable constituents. The process involves contacting said coal with a normally liquid hydrocarbon solvent for coal substance, agitating said coal particles with said solvent at a temperature above which said coal is rendered plastic and becomes miscible with said oil solvent and a substantially homogeneous liquid mixture containing all of the original components of said coal is obtained. The process continues by atomizing said liquid mixture into a stream of a substantially inert gas, passing the suspension upwardly through an externally heated carbonization zone maintained at a temperature of from about 900/sup 0/ to about 1300/sup 0/F, and maintaining said atomized liquid in suspension for a period of time sufficient to effect substantially complete volatilization of said hydrocarbon solvent. The volatilizable constituents of said coal form dry solid particles of coke suspended in vaporous product of volatilization and subsequently separating said solid particles of coke from volatilized products.
