Abstract
The present invention is directed to a process for producing endothermic gases from methanol and inert gas streams containing minor amounts of oxygen, wherein the oxygen is reacted with stoichiometric excess quantities of methanol over a catalyst as ambient feed temperature conditions without a requirement for external heating of the reaction to produce an endothermic gas containing very low levels of oxygen and methanol and significant quantities of hydrogen, carbon monoxide, water and carbon dioxide.
Claims11
A process for producing an endothermic gas comprising an inert gas, carbon monoxide, hydrogen, carbon dioxide and water by reacting an inert gas stream containing minor amounts of oxygen in the range of approximately 0.1 to 10 mole % with a stoichiometric excess amount of methanol at a feed gas temperature in the range of approximately 60.degree. to 120.degree. F. in the presence of a catalyst of approximately 0.05 to 1.0 wt % palladium in the metal form with a metal surface area of at least 0.4 m.sup.2 /g and a palladium dispersion of at least 30.0% to convert the oxygen and methanol to carbon monoxide, hydrogen, carbon dioxide and water without external heating of the reaction.
