Abstract :
The catalytic transformations of n-pentane were performed over a platinum-promoted silicoaluminophosphate molecular sieve (Pt/SAPO-11). The catalytic results indicate high yield for the production of pentenes with a good approach to the equilibrium distribution between the linear pentenes and iso-pentenes. The space velocity (WHSV) variation ranging between 1.6 and 4.7 h−1, and the catalyst regeneration did not affect the catalytic behavior of the Pt/SAPO-11. On the contrary, Pt reduction at a temperature below 500 °C, the H2/n-pentane molar ratio increase and Pt content below 0.5 wt.%, resulted in lower yield for the production of pentenes with an increase in the production of hydrocarbons with less than five carbon atoms (undesirable side reaction).
