Abstract
The present invention provides a method for the recovery of elemental carbon or soot produced during the partial oxidation reaction of a hydrocarbonaceous fuel and oxygen. An effluent stream of raw synthesis gas or syngas with entrained carbon soot is produced during the partial oxidation reaction. A filter cake ( ) is fed to a receiving bin ( ) and then to a lockhopper ( ) where the wet filter cake is pressurized. Wet filter cake/oil feed mixture from lockhopper ( ) is fed through line ( ) to knockout vessel ( ) wherein oil and water vapor exit ( ) to a gasifier. An oil feed/particulate carbon mixture exits lockhopper ( ) through lines ( ) and ( ) to oil feed storage drum ( ), fed by oil feed ( ), and exits water-free mixture of oil and solids ( ) to a gasifier reaction zone.
