Polymer-based spherical activated carbon in combination with TS-1 as an efficient epoxidation

The heterogeneously catalyzed epoxidation of commercial biodiesel with aqueous H sub(2)O sub(2) as oxidizing agent has been studied using composite catalysts composed of microporous titanium silicalite (TS-1) as a reactive, and a polymer-based spherical activated carbon as sorptive functionality.

description The heterogeneously catalyzed epoxidation of commercial biodiesel with aqueous H sub(2)O sub(2) as oxidizing agent has been studied using composite catalysts composed of microporous titanium silicalite (TS-1) as a reactive, and a polymer-based spherical activated carbon as sorptive functionality. The results were compared with the performance of a commercial TS-1 catalyst. The polymer-based spherical activated carbon was used either as a support or as exotemplate. The efficiency of the active titanium sites was four times higher in the composite catalyst than in the commercial TS-1 catalyst.Original Abstract: Die heterogen katalysierte Epoxidierung von kommerziellem Biodiesel mit waessrigem H sub(2)O sub(2) als Oxidationsmittel wurde an Kompositkatalysatoren aus mikroporosem Titansilikalit-1 (TS-1) als reaktiver und einer polymerbasierten sphaerischen Aktivkohle als sorptiver Komponente untersucht. Die Ergebnisse wurden mit denen eines kommerziellen TS-1-Katalysators verglichen. Die Polymer-basierte sphaerische Aktivkohle diente dabei als Traegermaterial oder als Exotemplat. In dem Kompositkatalysator werden die aktiven Titanatome viermal effizienter als in kommerziellem TS-1-Katalysator genutzt.
