ABSTRACT:
In a process for gasifying solid carbon sources such as coal utilizing zinc oxide as the oxygen donor, the carbon source is first contacted in a preheat zone with product gas; any zinc in this product gas is condensed on the carbon source; the preheated carbon source and zinc are then exposed to steam whereby the zinc is oxidized to zinc oxide; the mixture of zinc oxide and carbon source finally is reacted at elevated temperature conditions to form a gas comprising carbon monoxide and zinc.
