BEA zeolite nanocrystals dispersed over alumina for n-hexadecane hydroisomerization

► BEA germination on α-Al2O3 surface for nanocrystallites dispersion. ► Synthesis procedure does not affect the BEA zeolite physicochemical properties. ► BEA catalysts with low diffusion limitations. ► Composite catalyst attained high hydroisomerization activity and selectivity.
