Abstract:
Hydroisomerization of long chain n-alkanes has been playing an important role in the petroleum industry, in which heavy distillate and residue are converted into value-added products such as gasoline, jet fad; other middle distillates and lubricant oils. Herein, 10 ring zeolites, including ZSM-22, ZSM-23, ZSM-35, and ZSM-48 were studied for the process. ZSM-35 and ZSM-48 are relatively less studied zeolites as hydroisomerization reaction catalysts though they are expected to display interesting shape selective properties. A higher conversion was obtained over Pt-ZSM-35 and a higher selectivity was obtained over PtZSM-23 at low temperature and short contact time, and a higher selectivity was obtained over Pt-ZSM-48 at high temperature and long contact time, while the mixed catalysts displayed interesting,conversion and selectivity. Small differences in the channel system have a notable influence- on the product distribution,of hexadecane hydroisomerization over 10-ring zeolites. A combination of the evidence of no absence of multibrariCh6d products and the length of hexadecanemolecular could infer that hexadecane hydroisomerization includes a pore mouth, reaction mechanism.
