Claims22
A method for producing synthesis gas, the method computing:
- providing a first reactor comprising a first partial oxidation syngas catalyst system, wherein the temperature profile of the first reactor comprises a first area of a first elevated temperature and a first area of a first moderate temperature which is lower than the first elevated temperature;
- providing a second reactor comprising a second partial oxidation syngas catalyst system, wherein the temperature profile of the second reactor comprises a second area of a second elevated temperature and a second area of a second moderate temperature, wherein the second moderate temperature is lower than the first elevated temperature;
- providing a first reactor comprising a hydrocarbon gas and an oxygen-containing gas, wherein the first feedstream is fed through the first reactor and the first reactor is operated at conditions effective to partially oxidize at least a portion of the hydrocarbon gas to a first product stream comprising synthesis gas;
- providing a second feedstream comprising a hydrocarbon gas and an oxygen-containing gas, wherein the second feedstream is fed through the second reactor and the second reactor is operated at conditions effective to partially oxidize at least a portion of the hydrocarbon gas to a second product stream comprising synthesis gas;
- arranging the first and second reactors such that the first area of a first elevated temperature exchanges heat with the second area of a second moderate temperature.
