Abstract
The composite material on the base of Al2O3 and SAPO-11 was prepared with a various concentration on SAPO-11 and investigated as a carrier of bifunctional Pt-based catalyst for n-alkanes hydroisomerization. The Al2O3-SAPO-11 composite material with an optimal composition and acidic properties was used to prepare bifunctional catalysts with different hydrogenation/dehydrogenation sites. The effectiveness of the Pt, Pd, Ni and CoMoS active sites of bifunctional catalysts supported on the composite Al2O3-SAPO-11 carrier were investigated and compared in n-hexadecane hydroisomerization. Synthesized materials were investigated using X-ray powder diffraction, scanning electronic and high-resolution transition electronic microscopies, N2 physisorption, NH3-TPD and pyridine-FTIR spectroscopy. A CoMoS active phase was studied as hydrogenation/dehydrogenation hydrogenated-dehydrogenated active sites of bifunctional hydroisomerization catalysts.
