Catalytic Reagents
Oxidation technologies have proven effective in removing mercaptans from jet fuel, gasoline, diesel fuel, and other petroleum fractions. In these oxidation processes, catalysts specifically designed for mercaptan sweetening of petroleum fractions are critical to assuring process reliability and to minimizing operating costs.
| Catalytic Sweetening Process | Feedstock | Catalyst | Note |
|---|---|---|---|
| Extraction | Gases light liquids |
ARI-100EXL | Reduces total sulfur |
| Liquid-liquid | Easily-oxidized thiols, e.g., virgin and light cracked gasoline | ARI-100EXL | Total sulfur content unchanged |
| Fixed bed | Hard-to-oxidize thiols found in middle distillates such as kerosene, jet fuel, diesel, heating oil | ARI-120L | Total sulfur content unchanged |
