β-crystal formation of isotactic polypropylene under the combined effects of acid-corroded glass fiber and preshear
关键字：Mancun Xie, Baobao Chang, Hongli Liu, Kun Dai, Guoqiang Zheng(通讯作者), Chuntai Liu, Changyu Shen and Jingbo Chen
The acid-corroded glass fiber (GF)/isotactic polypropylene
(iPP) composite was injection molded by mixing–
injection molding (MIM). Through this method,
preshear can be imposed on melt during mix–plasticization
process. The crystalline structure across the
thickness direction of the injection-molded bars was
investigated by wide-angle X-ray diffraction and differential
scanning calo...

Continuous esteri?cation to produce biodiesel by SPES/PES/NWF composite catalytic membrane in ?ow-through membrane reactor: Experimental and kinetic studies
关键字：Continuous esteri?cation， Composite catalytic membrane， Oleic acid， Flow-through membrane reactor， Sulfonated polyethersulfone (SPES)
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...
