Abstract
The C60-filled ethyl cellulose hybrid membrane was prepared for removing sulfur from model gasoline by pervaporation (PV). The transmission electron microscopy (TEM) image of the microstructure of EC/C60 hybrid membrane showed the existence of C60 clusters in the hybrid membrane, which could resemble the path of electron-rich gasoline components through the membrane. The result of the PV performance using the ethyl cellulose (EC) membrane and the EC/C60 hybrid membrane showed that permeation flux increased as the operating temperature increased, but the sulfur enrichment factor increased first and then decreased. The change of cross-linking time did not influence the variation trends of permeation flux and sulfur enrichment factor with operating temperature. In addition, the linear fitting results proved that sound linearity existed between the permeation flux and the operating temperature; the apparent PV activation energy of EC/C60 hybrid membrane was lower than that of the pure EC membrane. Therefore, ...
