摘要：Effects of ytterbia for Pt-SO4 2-/ZrO 2-Al2O3-Yb2O3 (PSZAY) catalysts in n-hexane hydroisomerization were investigated. It was elucidated that the introduction of ytterbia into Pt-SO4 2-/ZrO 2-Al2O3 (PSZA) increased both the surface area and the number of active sites, resulting in a higher n-hexane isomerization activity. At the same time the catalyst stability has also been markedly increased by alleviating the sulfur loss and by stabilizing ZrO2 tetragonal crystalline structure. ?
