BEA zeolite
-
Tubular zeolite BEA membrane was prepared by a hydrothermal secondary growth method in the absence of an organic structure directing agent (OSDA). Membrane formation process was carefully observed by using FE-SEM, XRD, and N2 adsorption, and the role of seed crystals on the support surface was discussed.

The obtained catalysts were characterized by means of N2 sorption, XRD, Py–FTIR, FTIR, H2 chemisorption and TEM to determine the effect of the Pt precursor on their physicochemical properties. Catalytic performance of obtained catalysts was investigated in hydroisomerization of n-hexadecane.
