Novel environmental friendly process for reducing the sulphur level in fuel: pervaporation

0

Pervaporation (PV) is an alternative membrane-based process for removal of sulphuric components with low energy consumption. In PV, selective removal bases on the concentration difference between two sides of membrane. In sulphur removal process hydrophobic membranes are generally used due to the flexible chain structure. If the solution parameters and polarities of membranes are close to the sulphur components then hydrophilic membranes are preferred. In this study, pristine and wt. 3%, 5% and 10% of poly(oligosilsesquioxanes) (POSS) loading poly(dimethyl siloxane) (PDMS) membranes have been prepared for pervaporation experiment. Sorption and desorption experiments have been performed at room temperature to determine the swelling characters and sorption selectivity values of the membranes with respect to the sulphur concentration.
