Pervaporative Recovery of Bio-butanol through Dense- and Composite-type PDMS Membranes
Pervaporative Recovery of Bio-butanol through Dense- and Composite-type PDMS Membranesbio-Butanol;polydimethylsiolxane;pervaporation;composite;membrane;recovery;Bio-butanol recovery by pervaporation was performed with dense and composite polydimethylsiloxane (PDMS) membranes. The pervaporative behavior of the membranes was investigated as a function of operation temperature $(20{\\sim}40^{\\circ}C)$ and membrane thickness $(100{\\sim}1{\\mu}m)$ using a series of aqueous BtOH model solutions $(1{\\sim}5wt%)$.
