| titleOfInvention | Gas-phase in-situ oxidation preparation method of Mn-Ce-Fe-Co quaternary catalysis function PPS filter material |
| abstract | The invention discloses a gas-phase in-situ oxidation preparation method of a Mn-Ce-Fe-Co quaternary catalysis function PPS filter material, which takes a polyphenylene sulfide (PPS) filter material of a dust remover as a carrier, adopts a binder to carry out surface viscosity modification treatment on the polyphenylene sulfide (PPS), and contacts with ozone with the concentration of 10 mg/L-240 mg/L to carry out gas-phase oxidation after impregnation, adsorption and secondary low-temperature drying and dehydration, so that active metal ions are directly oxidized on the surface of the PPS filter material fiber in situ to be converted into an oxide form with high activity catalysis activity, and the preparation of the Mn-Ce-Fe-Co quaternary catalysis function PPS filter material is completed. The preparation method of the invention takes gas phase oxidation as a core innovation point, and has the advantages of wide material source, simple and stable gas storage, simple safety leakage inspection and high production safety. |
