Abstract
The present invention includes methods and apparatus for start-up a chemical reactor wherein at least a portion of the igniter is downstream from the reaction zone which needs to be ignited. Particularly, embodiments of the present invention include a partial oxidation reactor with an igniter downstream of the partial oxidation zone.
Claims44
A process for start-up of a thermally self-sustaining reaction, the process comprising:
- introducing a reactant stream to a reactor, wherein the reactor comprises:
- a reaction zone for conducting the thermally self-sustaining reaction;
- and
- an ignition zone in thermal contact with the reaction zone;
- wherein the at least a portion of the ignition zone is downstream of at least a portion of the reaction zone;
- wherein the ignition zone comprises an igniter;
- wherein the igniter ignites the reactant stream and starts-up the thermally self-sustaining reaction in the reaction zone.
A process for the production of liquid hydrocarbons, the process comprising:
- introducing a stream comprising a hydrocarbon-containing gas and an oxygen-containing gas to a reactor, wherein the reactor comprises:
- a reaction zone;
- and
- an ignition zone comprising an igniter;
- wherein at least a portion of the ignition zone is disposed downstream of and in thermal contact with the reaction zone;
- igniting the stream so as to initiate the partial oxidation reaction in the reaction zone to produce a product stream comprising synthesis gas;
- contacting at least a portion of the product stream with a catalyst in a hydrocarbon synthesis reactor so as to convert at least a portion of the synthesis gas to liquid hydrocarbons.
A reactor for producing synthesis gas from a feedstream comprising a hydrocarbon-containing gas and an oxygen-containing gas, the reactor comprising:
- a reaction zone for partially oxidizing the hydrocarbon gas to a product stream comprising synthesis gas;
- and
- an igniter in thermal contact with the reaction zone, wherein at least a portion of the igniter is downstream of the reaction zone and wherein the igniter ignites the hydrocarbon in the reaction zone so as to start-up the partial oxidation reaction in the reaction zone.
A means for initiating a thermally self-sustaining reaction, the means comprising:
- a means for reacting a reactant stream, wherein the means for reacting comprises:
- a reaction zone for conducting the thermally self-sustaining reaction;
- and
- means for igniting in thermal contact with the reaction zone;
- wherein the at least a portion of the means for igniting is downstream of at least a portion of the reaction zone.
