| 1. A method for preparing a hydrogen-rich stream and a carbon monoxide-rich stream, comprising:
reacting a methanol feed stream and oxygen, and optionally a temperature moderator, in a partial oxidation reactor to produce
a syngas stream, wherein the partial oxidation reactor is catalyst-free and operated at a temperature between 1100° and 2000°
C.;
separating the syngas stream into a carbon dioxide rich stream and a mixed stream containing hydrogen/carbon monoxide; and
separating the mixed stream into a hydrogen-rich stream and a carbon monoxide-rich stream.
