Method for non-aqueous phase wet oxidation of hydrogen sulfide

The invention relates to a new method for non-aqueous phase wet oxidation of hydrogen sulfide by taking iron-based ironic liquid as an oxidant. The iron-based ironic liquid is highly hydrophobic liquid which is insoluble in water, and can effectively absorb hydrogen sulfide gas and quickly and efficiently oxidize the hydrogen sulfide gas into elemental sulfur. After centrifugation separation or filtering separation is performed on the sulfur, the iron-based ironic liquid is recycled after being oxidized by air or pure oxygen. Water produced in the recycling process can be automatically separated from the hydrophobic iron-based ironic liquid to prevent dilution of the iron-based ironic liquid by the water. The pH of a reaction system is not required to be adjusted in the process of oxidizing the hydrogen sulfide by using the iron-based ironic liquid, and the acidic characteristic of the iron-based ironic liquid prevents the generation of a sulfur-containing byproduct in the reaction process. Over 90 percent hydrogen sulfide removal efficiency can be achieved and secondary pollution is not caused during the non-aqueous phase wet oxidation of the hydrogen sulfide by adjusting the circulating flow of the ironic liquid and the flow of the hydrogen sulfide gas by an absorption-oxidation-separation-regeneration combined process.
