Abstract

C5/C6 hydrocarbon isomerization is a mild reforming process, which is used to obtain gasoline with high octane number. Zirconium sulfate catalyst is a representative of a new generation of catalysts in the isomerization process, which has properties of high efficiency and is environmentally more acceptable than the current commercial chlorinated aluminum oxide.
In order to study isomerization process on the zirconium sulfate catalyst (Pt/SO4-ZrO2), laboratory apparatus for the isomerization process of light hydrocarbons in the presence of hydrogen is designed. By conducting a series of experiments and analysis of five key components: n-hexane, 2-methylpentane, 3-methylpentane and 2,2- and 2,3-dimethylbutanes, as well as cracking products, the impact of temperature and space velocity on the product composition of the isomerization process of n-hexane on zirconium-sulfate catalyst is described and explained. Obtained results show n-hexane conversion increase with the temperature increase and space velocity decrease in the investigated range of values, but is accompanied with the unwanted cracking reactions increase.
