Description

This repository includes experimental data associated with the publication: N.Korica, A.Ben Hassine, H.Dao Thi, L.Bergaoui, K.Van Geem, P.S.F.Mendes, J.De Clercq, J.W.Thybaut “Mixture effects in alkane/cycloalkane hydroconversion over Pt/HUSY : carbon number impact”, submitted to Fuel journal in December 2021.

The impact of carbon number of reacting alkanes and cycloalkanes on mixture effects in hydroconversion over Pt/HUSY has been studied by experiments on high-throughput setup by feeding equimolar mixtures of n-octane and tert-butylcyclohexane, and n-decane and methylcyclohexane.  In order to investigate the above-mentioned impact, the kinetic behavior was examined at various experimental conditions, over Pt/HUSY catalyst with three different Pt loadings and HUSY zeolite with Si/Al molar ratio of 6.

The process conditions which were used for every feed are summarized:

  • Pure n-octane
    • Catalysts : 0.07 and 0.1 wt%Pt/HUSY (poorly- and well-balanced catalyst for pure n-octane)
    • Temperature, K : 523 ; 543
    • Pressure, bar : 10 ; 20
    • Partial pressure of reactant, bar : 0.05
  • Pure tert-butylcyclohexane
    • Catalysts : 0.07 and 0.3 wt%Pt/HUSY
    • Temperature, K : 523 ; 543
    • Pressure, bar : 10 ; 20
    • Partial pressure of reactant, bar : 0.05
  • Equimolar mixture of n-octane and tert-butylcyclohexane
    • Catalysts : 0.07 and 0.3 wt%Pt/HUSY
    • Temperature, K : 523 ; 543
    • Pressure, bar : 10 ; 20
    • Partial pressure of each reactant, bar : 0.05
  • Pure n-decane
    • Catalysts : 0.07 and 0.3 wt%Pt/HUSY (poorly- and well-balanced catalyst for pure n-decane)
    • Temperature, K : 523 ; 543
    • Pressure, bar : 10 ; 20
    • Partial pressure of reactant, bar : 0.05
  • Pure methylcyclohexane
    • Catalysts : 0.07 and 0.1 wt%Pt/HUSY
    • Temperature, K : 523 ; 543
    • Pressure, bar : 10 ; 20
    • Partial pressure of reactant, bar : 0.05
  • Equimolar mixture of n-decane and methylcyclohexane
    • Catalysts : 0.07 and 0.3 wt%Pt/HUSY
    • Temperature, K : 523 ; 543
    • Pressure, bar : 10 ; 20
    • Partial pressure of each reactant, bar : 0.05
