ABSTRACT:
A high efficiency catalyst for use in a catalytic partial oxidation process for the production of hydrogen or syngas gas from hydrocarbons is disclosed. The catalyst comprises rhenium in combination with a second metal selected from the group of rhenium to second metal of 25:1 to 1:1. the process comprises reacting a feed containing hydrocarbons with an oxygen source at a C/O ratio of about 0.9 to 1.1 in the presence of the catalyst, and wherein the gas hourly space velocity of the feed over the catalyst ranges from about 1,000 hr−1to about 2,000,000 hr−1. In the process, the catalyst is maintained as a temperature of from about 500° C. to about 1,500° C. as the feed makes contact with the catalyst.
