1. A process for producing synthesis gas comprising the steps of:
- reacting a hydrogen-containing stream with an oxygen-containing stream and producing an oxidized stream comprising water;
contacting a feedstream comprising hydrocarbon or hydrocarbon comprising at least one atom of oxygen with said oxidized stream comprising water and forming a reforming feedstream; and
passing said reforming feedstream into a reforming reaction zone at reforming reaction conditions and producing a synthesis gas product.

11. A process for producing synthesis gas comprising the steps of:
-
oxidizing at least a portion of a hydrogen-containing stream with an oxygen-containing stream in an amount ranging from about 80 mole % to about 105 mole % of the stoichiometrically required amount of oxygen required to fully oxidize said hydrogen-containing stream to water, carbon dioxide or both and producing an oxidized stream comprising water at elevated temperature;
contacting a feedstream comprising hydrocarbon or hydrocarbon comprising at least one atom of oxygen with said oxidized stream comprising water and forming a reforming feedstream; and
passing said reforming feedstream into a steam reforming reaction zone at steam reforming reaction conditions and producing a synthesis gas product. - View Dependent Claims (12, 13, 14, 15, 16)

17. A process for producing synthesis gas comprising the steps of:
-
oxidizing at least a portion of a hydrogen-containing stream with a stream comprising oxygen such that more than 60 mole % of said hydrogen-containing stream is oxidized to water, carbon dioxide or both in said reacting step and producing an oxidized stream comprising water at elevated temperature;
contacting a hydrocarbon feedstream with said oxidized stream comprising water and forming a reforming feedstream; and
passing said reforming feedstream into a steam reforming reaction zone at steam reforming reaction conditions and producing a synthesis gas product, wherein a substantial portion of the steam reforming heat of reaction is provided by said oxidizing step. - View Dependent Claims (18, 19, 20)
