ABSTRACT:
Mercaptans and olefins are removed from paraffin-rich feed streams through the use of dual zone catalytic distillation in the substantial absence of hydrogen. The mercaptans are reacted with the olefins using a first catalyst such as a sulphonated resin to form less volatile thioethers removed as part of a net bottoms stream. The remaining olefins are oligomerized in a higher catalyst zone preferably employing a catalyst, such as a dealuminated Y zeolite, having a higher oligomerization activity at the imposed conditions.
