A catalyst system and processes for combined aromatization and selective hydrogen combustion of oxygenated hydrocarbons are disclosed. The catalyst system contains at least one aromatization component and at least one selective hydrogen combustion component. The process is such that the yield of hydrogen is less than the yield of hydrogen when contacting the hydrocarbons with the aromatization component alone.

The process of claim 1, wherein the selective hydrogen combustion is accomplished without a feeding of free-oxygen containing gas into the reactor. 3. The process of claim 1, wherein the feed comprises methanol and the process is conducted at a temperature from about 300° C. to about 800° C. and a pressure from 1 to 20 atmospheres absolute (101 to 2064 kPa). 4. The process of claim 1, further comprising the step of removing heat from the process where the removed heat is less than 90% of the removed heat required in a hydrocarbon conversion process for converting an oxygenate hydrocarbon feed to aromatics operated under the same conditions without a selective hydrogen combustion component in the catalyst system. 5. The process of claim 1, wherein added heat is required to maintain a steady conversion temperature. 6. The process of claim 1, wherein a yield of hydrogen is at least 10% less than the yield of hydrogen when converting said oxygenated hydrocarbon feed(s) under the same conditions without a selective hydrogen combustion component in the catalyst system. 7. The process of claim 1, wherein the at least one metal from Groups 11-15 of the Periodic Table of Elements is selected from the list consisting of copper, zinc, aluminum, gallium, germanium, silver, tin, antimony, and bismuth. 8.
