Abstract

Die vorliegende Erfindung betrifft einen Schalenkatalysator für die Herstellung von Vinylacetat-Monomer, umfassend einen oxidischen porösen Katalysatorträger mit einer äußeren Schale, enthaltend metallisches Pd und Au, wobei die Gerüststruktur des porösen Katalysatorträgers Hafniumoxideinheiten enthält. Dieser Schalenkatalysator ist für die Herstellung von VAM geeignet und zeichnet sich durch eine verhältnismäßig hohe Aktivität und VAM-Selektivität aus und behält über verhältnismäßig lange Standzeiten hinweg diese Aktivität und Selektivität bei. Außerdem betrifft die vorliegende Erfindung ein Verfahren zur Herstellung des Schalenkatalysators.
