Kinetic study of hydroisomerization of n-decane using Pt SAPO11 catalysts

Abstract EN

The hydroisomerization of n-decane was studied on SAPO-11 catalyst.

Catalyst of 0.25wt.%Pt/SAPO-11 was prepared locally and used in the present work.

The hydroconversion performed in a continuous fixed-bed laboratory reaction unit.

Experiments of ndecane isomerization were performed in a temperature range of 200 to 275°C,LHSV range of 0.5-2 h-1 , and hydrogen to decane mole ratio of 2.1-8.2.

The results show that the n-decane conversion increases with increasing temperature and decreasing LHSV , the maximum conversion 56.77 % was achieved at temperature 275°C and LHSV of 0.5 h-1 .

The kinetic of n-decane isomerization was also studied and the reaction was first order.

The kinetic analysis also showed that the activation energy equal to 61.1137 kJ/mol.
