Title
Influence of synthesis method on the properties and catalytic performance of MCM-49 zeolites
Abstract

Highly crystalline and pure MCM-49 was hydrothermally synthesized by dynamic and static methods, respectively. The properties of the samples were studied by N2 adsorption, XRD, TEM and FT-IR techniques. The results indicated that MCM-49 synthesized by dynamic method showed much smaller crystal and lower concentration of acid sites. The Pd-supported catalyst on MCM-49 synthesized by static method showed higher acetone conversion in one-step synthesis of methyl isobutyl ketone from acetone, which was attributed to higher concentration of acid sites. While the higher selectivity to methyl isobutyl ketone for Pd-supported on MCM-49 synthesized by dynamic method might be related with the lower acidity and higher BET surface area.
