Continuous esteri?cation to produce biodiesel by SPES/PES/NWF composite catalytic membrane in ?ow-through membrane reactor: Experimental and kinetic studies
A novel composite catalytic membrane (CCM) was prepared from sulfonated polyethersulfone (SPES) and polyethersulfone (PES) blend supported by non-woven fabrics, as a heterogeneous catalyst to produce biodiesel from continuous esteri?cation of oleic acid with methanol in a ?ow-through mode. A kinetic model of esteri?cation was established based on a plug-?ow assumption. The effects of the CCMstruct...
