碩士 === 東海大學 === 化學工程學系 === 96 === The purpose of this thesis is to study four carriers for propylene polymerization and to use the impregnation method for preparing silica supported catalyst. Three methods were used to prepare the four carriers, including rice husk ash method, Stöber Method and nano solution. The four carriers were used to carry out the propylene polymerization in a slurry reactor. We studied the effects of support types, support particle size , catalyst types, cocatalysts types and reaction temperature on polymer yield. We characterized the catalysts and the polymers with a variety of techniques, including DSC, GPC, FESEM, HRTEM, XRD, FTIR and ICP-AES. We found that M/T6000 particle size was only 5nm had the best yield and produced the highest melting point (Tm) polymer in propylene polymerization. We also found that Et(Ind)2ZrCl2 catalyst had the best yield, but its product had lower melting point (Tm) than the polymers produced with Me2Si(Ind)2ZrCl2 catalyst. With the MAO addition of 2ml in propylene polymerization, the yield and the polymer melting point (Tm) were good.
