Pretreatment method for TBP-kerosene organic solvent for supercritical water oxidation

The invention relates to a pretreatment method for supercritical water oxidation of a TBP-kerosene organic solvent. The method comprises the following steps: storing the TBP-kerosene organic solvent into a container; adding deionized water into a container in which the TBP-kerosene organic solvent is stored; adding span 80 into a container in which the TBP-kerosene organic solvent is stored; adding n-butanol into the container in which the TBP-kerosene organic solvent is stored, thereby forming a mixture; and stirring the mixture in the container by using an emulsifying machine to uniformly mix the mixture to form an emulsified mixture, stopping stirring, and keeping the emulsified mixture in a stable state within a preset time without generating precipitation or layering. According to the method disclosed by the invention, the TBP-kerosene organic solvent can exist in a very stable emulsified state for more than 4 hours, so that a uniform stable state with enough duration is provided for the organic solvent
