Interplay of metal-acid balance and methylcyclohexane admixture effect on n-octane hydroconversion over Pt/HUSY

This repository includes experimental data associated with the publication: N.Korica, P.S.F.Mendes, J.De Clercq, J.W.Thybaut "Interplay of metal-acid balance and methylcyclohexane admixture effect on n-octane hydroconversion over Pt/HUSY", submitted to Industrial & Engineering Chemistry Research journal in May 2021.

The impact of methylcyclohexane admixture on n-octane hydroconversion (isomerization and cracking) has been studied by experiments performed on high-throughput setup over Pt/HUSY catalyst with four different Pt loadings. Furthermore, the feed to reactor was varied for all examined catalysts from pure n-octane, over equimolar mixture of n-octane and methylcyclohexane, to pure methylcyclohexane. 

The process conditions which were used for every Pt loading are further summarized:

The catalytic activity of tested catalysts was compared based on conversion of both reactants, yields of octane isomers, selectivities to mono- and dibranched octane isomers, and selectivities to isomers of methylcyclohexane. These data are classified based on figures in the Article were they are shown.
