| titleOfInvention | Preparation method of pervaporation hybrid membrane for gasoline desulfurization |
| abstract | The invention provides a preparation method of a pervaporation hybrid membrane for gasoline desulfurization, which comprises a porous support base membrane and an oligomeric silsesquioxane/polyethylene glycol composite layer coated on the porous support base membrane, namely a POSS/PEG composite layer, wherein the POSS/PEG composite layer is prepared by filling POSS particles into a PEG membrane solution. The POSS/PEG hybrid membrane is applied to gasoline desulfurization, has high sulfur-rich factor and good permeation flux, breaks through the highest sulfur-rich factor of 12.59 of a pure PEG membrane and an inorganic particle filled PEG membrane reported in documents, and the sulfur-rich factor of the hybrid membrane obtained by the invention is 33.4 under the optimal condition for thiophene/n-heptane solution with the concentration of 500ppm and the permeation flux of 0.621kg/m 2 And h, the sulfur-rich factor far exceeds the highest value reported in the current literature, and the method has a good industrial application prospect. |
