The Promoting Effect of Ga2O3 on a Pt/WO3/ZrO2 Catalyst for n-Heptane Isomerization

Abstract

Abstract: The incorporation of small amounts of Ga2O3 into Pt/WO3/ZrO2 increases the activity substantially and improves the isomerization selectivity to some extent for n-heptane hydroisomerization. Pt/WO3/Ga2O3-ZrO2 gave a constant catalytic activity at 200 oC for over 80 h with a high n-C7 conversion (76%) and C7 isomer selectivity (94%).

Key words: platinum, tungsten oxide, zirconia, gallium oxide, n-heptane hydroisomerization, acidity
