Abstract

This study successfully improved the performance of oxidative desulfurization method to reduce sulfur content from residue oil (condensate) with modifications of oxidation and extraction steps epeated for several stages. Residue oil used in this study contained 386.2 ppm of initial sulfur content. In oxidation process, H2O2 as oxidizer and acid as catalyst were used within temperature range of 30–60 °C and for interval time from 30 to 120 min. In extraction process, various alcohol solvents (methanol, ethanol, and propanol) were used at the temperature of 30 °C for 30 min toward every ratio of residue oil to solvent (v/v). The best reducing sulfur result was 35.9 ppm or 90.7% desulfurization, and it was achieved after 4 recursively extractions using ethanol as the solvent. This study successfully reduced sulfur content in residue oil to meet the international standard (< 50 ppm).
