ABSTRACT
OATS [Olenic Alkylation of Thiophenic Sulfur] A gasoline desulfurization process. Thiophenes and mercaptans are catalytically reacted with olens to produce higher-boiling compounds that can more easily be removed by distillation prior to hydrodesulfurization. This minimizes hydrogen usage. The process uses a solid acid catalyst in a liquid-phase, xed-bed reactor. Developed by BP Amoco in 2000 and tested in Bavaria and Texas. First used commercially at the Bayernoil renery, Neustadt, in 2001. The process won a European Environment Award in 2002.
