Catalytic Partial Oxidation Reforming for Syngas Processing and Products Made Therefrom
First Claim
1. ) A process for producing syngas and one or more hydrocarbon products therefrom, comprising:
- partially oxidizing a first hydrocarbon in the presence of an oxidant and one or more first catalysts at conditions sufficient to partially combust a portion of the first hydrocarbon to provide carbon dioxide, non-combusted first hydrocarbon, and heat;
reforming at least a portion of the non-combusted hydrocarbon in the presence of at least a portion of the heat generated in the partial oxidation step and the one or more first catalysts to provide a first syngas comprising hydrogen, carbon monoxide, and carbon dioxide;
indirectly exchanging heat from the first syngas to a second hydrocarbon to reform at least a portion of the second hydrocarbon in the presence of steam and one or more second catalysts to provide a second syngas comprising hydrogen, carbon monoxide, carbon dioxide, and water; and
reacting the first syngas, the second syngas, or a mixture thereof to provide a tail gas and one or more Fischer-Tropsch products, derivatives thereof, or combinations thereof.

Abstract
Systems and methods for producing syngas are provided. A first hydrocarbon can be partially oxidized in the presence of an oxidant and one or more first catalysts at conditions sufficient to partially combust a portion of the first hydrocarbon to provide carbon dioxide, non-combusted first hydrocarbon, and heat. The non-combusted first hydrocarbon can be reformed in the presence of the heat generated in the partial oxidation step and the one or more first catalysts to provide a first syngas. Heat can be indirectly exchanged from the first syngas to a second hydrocarbon to reform at least a portion of the second hydrocarbon in the presence of steam and one or more second catalysts to provide a second syngas. A syngas, which can include the at least a portion of the first syngas, at least a portion of the second syngas, or a mixture thereof can be converted to provide one or more Fischer-Tropsch products, methanol, derivatives thereof, or combinations thereof.
