Selective Synthesis of 1,3-Butadiene through n-Butane Dehydrogenation over Metal-containing Zeolite Catalyst

Abstract

Metal-containing MFI-type zeolites were hydrothermally synthesized in the absence of Al species and alkali cations and used for the direct dehydrogenation of n-butane to evaluate the catalytic properties. Zn-, Fe-, and Ni-containing MFI zeolites exhibited high catalytic activities, and predominantly produced 1,3-butadiene. Furthermore, Zn-containing MFI zeolites prepared by hydrothermal treatment in the absence of alkali cations showed significantly higher yields of 1,3-butadiene compared to ZnO loaded on silicalite-1 by impregnation.
