Reactor system for producing synthesis gas

A partial oxidation reactor generating synthesis gas, comprising:

• a reactor vessel including therein a defined reaction zone having a reaction zone inlet and a reaction zone outlet wherein the reaction zone is catalyst free, an injector section to inject reactants including a hydrocarbon stream and oxygen to the reaction zone inlet to produce a stream of synthesis gas, wherein the injector section includes a hydrocarbon stream injector and an oxygen injector, a coolant injector to inject a coolant downstream from the reaction zone outlet to cool the stream of synthesis gas discharged from the reaction zone outlet, and a reactor vessel outlet downstream of the coolant injector for discharging the synthesis gas;
• a controller in operational control with at least the coolant injector to control injection of the coolant to cool the stream of synthesis gas discharged from the reaction zone outlet and upwardly shift the H2:CO ratio in the synthesis gas to a target ratio;
• wherein reaction between hydrocarbon and oxygen in the reaction zone generates heat;
• and
• wherein the temperature of the synthesis gas as the synthesis gas discharges from the reaction zone outlet is approximately 2400° F. and wherein the controller controls injection of coolant downstream of the reaction zone outlet to cool the synthesis gas to approximately 700° F.
