Abstract
A method of feeding powdered coal to a high pressure reactor which is being used with a fluidized bed/entrained flow coal gasification process. It includes steps of feeding a moist powdered coal to an extruder, and extruding the mixture into a high pressure stream of gas. The extrudate is dispersed into the gas stream, and the stream of extrudate and gas carrier is dried. Then the dry extrudate is separated and fed into the reactor vessel.
