A study on isomerization of the gasoline fraction of C7 hydrocarbons on the Pt/WO3/ZrO2 catalyst

Abstract

Isomerization of n-heptane and its mixture with methylcyclohexane (MCH) taken in a ratio of 2/1, 1/1 and 1/2 on the Pt/WO3/ZrO2 catalyst was studied. It was found that octane number of the catalyzate increases with the MCH content in the initial feed over the temperature range of 170-270 °C. The isomerization selectivity of n-heptane and the yield of isomers do not depend on the composition of the initial feed. The yield of C5+ catalyzate with a fixed octane number also increases with the MCH content in the feed.Isomerization of n-heptane and its mixture with methylcyclohexane (MCH) taken in a ratio of 2/1, 1/1 and 1/2 on the Pt/WO3/ZrO2 catalyst was studied.
