Abstract
The effect of the nature of modifying agent and chemical composition on the phase state, texture characteristics and acid properties of Р2O5–Al2O3, МоO3–Al2O3, and WO3–Al2O3 systems was studied. Supported platinum catalysts based on these systems were tested in hydroisomerization of a model mixture of heptane and benzene in a flow set-up at reaction temperature of 300–350 °C, pressure 1.5 MPa, mass rate of raw material input 3.0 h–1, molar ratio of Н2/raw material equal to 5. A Pt/WO3–Al2O3 sample with WO3 25.9 mass % was chosen as a promising catalyst of hydroisomerization.
