Advanced Study of Promoted Pt /SAPO-11 Catalyst for Hydroisomerization of the n-Decane Model and Lube Oil

SAPO-11 is synthesized from silicoaluminophosphate in the presence of di-n-propylamine as a template. The results show that sample obtained has good crystallinity, 396m2/g BET surface area, and 0.35 cm3/g pore volume. hydroisomerization activity (0.25)Pt (1)Zr (0.5)W/SAPO-11 catalyst was determined using n-decane base oil. All experiments were achieved at fixed bed plug flow reactor temperature range 200-275°C LHSV 0.5-2h-1. conversion increases with increasing decreasing LHSV, maximum 66.7 % 275°C 0.5 h-1. Meanwhile, same used to improve oil specification by viscosity index pour point. isomerization reaction conditions, employed are (200-300)ºC, liquid hourly space velocity 0.5-2h-1, pressure kept atmospheric. present study shows Pt Zr W/SAPO-11 minimizes point lubricating -16°C 300°C h-1 134.8.
