Method for controlling reaction temperature

摘要

Oxidation reactions occurring in a plug flow reactor under conditions approximating supercritical water conditions are controlled by injecting a process stream of water and two reactants in non-stoichiometric proportions into the reactor and causing the process stream to flow through the reactor. Water is injected at one or more points downstream from the inlet to lower the temperature of the process stream and additional reactant injected to re-start the reaction. The quench and re-start process is repeated until substantially all oxidizable material in the process stream has be oxidized.
