Claims41
A method for producing a product stream comprising syngas from a feedstrearn comprising light hydrocarbons and molecular oxygen, the method comprising:
- providing a reactor vessel comprising a reaction zone and a cooling device;
- reacting the light hydrocarbons and the oxygen in the reaction zone configured to catalytically partially oxidize at least a portion of the light hydrocarbons to a syngas comprising at least about 70 mol % H2 and CO;
- and
- flowing at least a portion of the syngas directly into the cooling device,
- wherein at least a portion of a syngas exposed surface of the reactor vessel outside of the cooling device, a syngas exposed surface of the cooling device, or both comprise an alloy comprising primarily nickel.
A method for producing C5+ hydrocarbons from a feedstream comprising C1–C4 light hydrocarbons and molecular oxygen, the method comprising:
- providing a reactor vessel comprising a reaction zone and a cooling device, said reaction zone comprising a catalyst zone;
- reacting the feedstream comprising C1–C4 hydrocarbons and oxygen in the reaction zone to catalytically partially oxidize at least a portion of the feedstrean comprising C1–C4hydrocarbons to a syngas comprising at least about 70 mole percent H2 and CO;
- flowing at least a portion of the syngas leaving the catalyst zone directly into the cooling device,
- wherein at least a portion of a syngas exposed surface of the reactor outside of the cooling device, a syngas exposed surface of the cooling device, or both comprise an alloy comprising primarily nickel;
- and
- feeding at least a portion of the cooled syngas into a hydrocarbon synthesis reactor, wherein at least a portion of the syngas is converted to C5+ hydrocarbons.
A method for cooling a hydrocarbon partial oxidation product stream exiting a catalyst zone, the method comprising:
- providing a reactor vessel having a reaction zone comprising a catalyst zone configured to catalytically partiaily oxidize a light hydrocarbons to syngas and a cooling zone comprising at least one cooling device;
- feeding at least a portion of the stream leaving the catalyst zone directly through at least one said cooling device, wherein at least a portion of a syngas exposed surface of the cooling device comprises an alloy comprising primarily nickel;
- and
- wherein the hydrocarbon partial oxidation stream is generated in part or totally over a partial oxidation catalyst contained in said catalyst zone and comprises at least 70% H2 and CO.
