The n-heptane isomerization was comparatively investigated over various catalysts, and significantly higher n-heptane conversion and isomerization selectivity were achieved with Pt/SBA-15 catalyst. The kinetics of n-heptane isomerization has been examined as a function of n-heptane and hydrogen pressures at various temperatures. Two kinetics model based on power law and Langmuir-Hinshelwood mechanism were developed for the reaction and compared with the obtained experimental data. The apparent kinetics parameters were estimated using multiple regression analysis. The reaction order is positive for n-heptane over most catalysts, suggesting strong coverage and negative order with respect to H-2, indicating the inhibitory effect of H-2.
