## Abstract

The present invention relates to integrating a hot oxygen burner with an auto thermal reformer of reducing in a system for generating synthesis gas.

## Claims

### Claim 1

A method for generating syngas in a thermal reactor, comprising:
introducing a first stream of fuel and oxygen in a hot oxygen burner to combust said fuel and generate a hot oxygen jet having a burner stoichiometric ratio (SR) value between 3 and 6 wherein the hot oxygen burner is integrated with the auto thermal reactor;
introducing a first hydrocarbon stream within a non-catalytic zone of the auto thermal reactor, wherein the first hydrocarbon stream is substantially entrained in the hot oxygen jet; reacting the first hydrocarbon stream with the hot oxygen jet, performing partial reforming of the hydrocarbon in the non-catalytic zone of the auto thermal reactor, and completing the reforming in a catalytic reaction zone of the auto thermal reactor, thereby forming a syngas which exits the reactor at a temperature below 2000° F. and with minimal soot formation.

### Claim 2 (depends on 1)

The method of claim 1, wherein a first stream of fuel stream as an opportunity fuel.

### Claim 3 (depends on 1)

The method of claim 1, further comprising:
routing a second stream of hydrocarbon to upstream of the catalytic reaction zone of the auto thermal reactor.
