ABSTRACT:
This invention concerns a carbonization and desulfurization process in which elevated pressures are used so that the product gases contain sufficient hydrogen for use as a recycle stream in the carbonization and desulfurization. The elevated pressures permit product recovery systems for the gas products which utilize the elevated pressures of the carbonization and desulfurization.
