Abstract
Production of clean fuel gas having a high heating value by means of two interconnected free-flow noncatalytic partial oxidation gas generators. All of the particulate carbon produced in the effluent gas stream from both generators is recovered and burned as a portion of the feedstock in gas generator two to maximize the methane yield in gas generator one. At least a portion of the cooled and cleaned effluent gas from gas generator 2 is recycled to gas generator 1 as the temperature moderator. The cooled, cleaned, and purified effluent gas stream from gas generator one has a minimum heating value of 400 BTU/SCF and a minimum methane content of 5.0 mole % (dry basis).
