Reduction of metal oxides using a gas stream containing both hydrocarbon and hydrogen

摘要

The invention relates to a process for reducing metal oxides using a gas stream containing both hydrocarbon and hydrogen. In the process the gas stream containing both hydrocarbon and hydrogen is separated into a hydrogen-rich fraction and a hydrocarbon-rich fraction. Then at least one sub-quantity of the hydrocarbon-rich fraction is subjected to at least one operation from the group - oxidation using technically pure oxygen, - reforming using CO
