La-Ni modified S2O82-/ZrO2-Al2O3 catalyst in n-pentane hydroisomerization

摘要

The La-Ni-S2O82-/ZrO2-Al2O3 (La-Ni-SZA) was prepared and the effect of La and Ni on the structure and isomerization performance of catalyst was investigated. The addition of La could lead to a higher dispersion of metal and more acid sites. The addition of Ni can promote redox performance of catalyst and formation of Lewis acid sites. The highest isopentane yield of 66.5% at a lower reaction temperature of La-Ni-SZA can be attributed to the synergistic interaction between La and Ni. (C) 2014 Elsevier B.V. All rights reserved.
