ABSTRACT:
A process is disclosed for reducing the level of sulfur compounds from liquid conjugated diolefin hydrocarbons by contacting said sulfur compound-bearing hydrocarbon liquids with sorbents prepared by combining particulate alumina with at least one compound decomposable to of sodium oxide, barium oxide, calcium oxide or a salt decomposable to potassium oxide, but excluding potassium carbonate and potassium bicarbonate and calcining. The process is particularly useful for removal of hydrogen sulfide and carbon disulfide from butadiene and isoprene.
