Pt-promoted HY@KCC-1 as a highly selective catalyst for hydroisomerization of n-dodecane with enhanced mass transfer limitation.
A unique core-shell fibrous silica zeolite HY (HY@KCC-1) catalyst with high surface area of 568 m2/g was successfully synthesized via a facile silica solvothermal procedure coupled with zeolite crystalseed crystallization, and subsequently investigated for n-dodecane hydroisomerization.
