ABSTRACT:
A process for making a synthesis gas comprising H.sub.2 and CO in the presence of a reforming catalyst comprising a supported non-noble Group VIII metal catalytic component from a feed including a low molecular weight alkane, and preferably methane as in natural gas, O.sub.2, H.sub.2 O and CO.sub.2 without catalyst deactivation is achieved by partially oxidizing and steam reforming the feed in the presence of the catalyst. The feed H.sub.2 O to hydrocarbon carbon mole ratio is less than 2. The mole ratio of the combined feed CO.sub.2 and H.sub.2 O to hydrocarbon carbon ranges from 0.5-2.5 and that of the feed H.sub.2 O to CO.sub.2 ranges from 0.35-6. Synthesis gas having H.sub.2 to CO mole ratios less than 2:1 and even less than 1.5:1 are easily achieved with net CO.sub.2 consumption, which also makes the process environmentally beneficial.
