Abstract
In the gasification of char with zinc oxide, the improvement which comprises reacting the off-gas stream of gaseous zinc and carbon monoxide with steam at elevated temperatures in a second reactor means thereby oxidizing the zinc to zinc oxide and yielding a second gaseous stream containing carbon monoxide and hydrogen. This improved process avoids having to condense and revaporize the zinc, heretofore an economic barrier to the development of the zinc oxide char processes.
