Synthesis and characterization of sulfated zirconia catalyst for light naphtha isomerization process

Abstract EN

The platinum-loaded zirconium oxide (Pt/SO4-2/ZrO2) catalyst was developed for the light naphtha atoms over the reaction temperature range of 160 to 220 °C, 1 and 3 h-1 LSHV and 10 bar.

Platinum improved the stability of the catalyst by preventing the formation of a coke precursor at the strong acid site of sulfur zirconium.

The acidity of the catalyst was characterized by of NH3-TPD and the effect of sulfur and calcination temperature on the surface area of the final prepared zirconia was studied.

The prepared catalyst shows high structural similar activity at temperature between 200 and 210°C for two types of light naphtha catalyst was developed for the light naphtha atoms over the reaction temperature range of 160 to 220 °C, 1 and 3 h-1 LSHV and 10 bar.

The prepared catalyst shows high structural similar activity at temperature between 200 and 210°C for two types of light naphtha feed.
