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.

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
