Abstract: A method for purifying 1-hexene is disclosed. The method can include contacting a first stream containing 1-hexene and 2-ethyl-1-butene with an isomerization catalyst containing an comprising an alumina, silica-alumina, a zeolite, or an ion exchange resin, or any combinations thereof, under conditions sufficient to selectively isomerize at least a portion of 2-ethyl-1-butene into 3-methyl-2-pentene and form a second stream containing 1-hexene and 3-methyl-2-pentene, and separating the second stream into a third stream containing 1-hexene and a fourth stream containing 3-methyl-2-pentene.

Abstract: Disclosed are methods and systems for desulfurization of CO-rich streams. A method can include contacting a CO-rich gas stream with activated carbon and/or contacting the CO-rich gas stream with a zinc-oxide sorbent material at a temperature of 0 to 50° C. to remove at least a portion of the sulfur-containing compounds present in the stream.

Abstract: The disclosure provides a method of purifying a linear alpha olefin product, the method including feeding a linear alpha olefin feed stream comprising the linear alpha olefin product and at least one impurity into a distillation column, the distillation column having a plurality of stacked stages; withdrawing a side stream from at least one of said plurality of stacked stages; feeding the side stream into a reactor containing an isomerization catalyst to convert at least a portion of the at least one impurity from a first isomer to a second isomer, producing a reactor product stream having a reduced content of the first isomer; returning the reactor product stream to a stage of the distillation column; and withdrawing an overhead stream from the distillation column comprising the linear alpha olefin product and having a reduced content of the at least one impurity.
