Method of gas production

Patent ·
OSTI ID:6746812
This patent describes a process of generating mixed water gas and coal gas by the use of a plurality of similar units. The process consists of alternately air blasting and steaming through carbonaceous residue in certain of said units, passing the water-gas generated through heated carbonaceous residue in another unit, passing the heated gas through a body of fresh coal in said latter unit (the sensible heat of the gas serving to largely remove the volatile contents of the coal thereby producing mixed water gas and coal gas), and agitating the mass of coal.
