ABSTRACT:
Contaminants such as mercaptans, oxygenates and olefins are removed from paraffin-rich feed streams through the use of catalytic distillation performed using an acid catalyst such as a sulphonated resin in the substantial absence of hydrogen. The mercaptans are reacted with the olefins to form less volatile thioethers removed as part of a net bottoms stream with the treated paraffins being removed as the overhead stream.
