Abstract: A method of purifying alcohol produced in a process that includes the Oxo process is disclosed. Aldehyde from the Oxo process that remains with the alcohol is removed by a reaction with an alkali sulphite to produce an insoluble adduct and alcohol having a reduced amount of aldehyde mixed with it. The adduct is removed from the alcohol by filtration.

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: A method of recovering 2-ethyl hexanol (2-EH) from crude alcohol that includes the 2-ethyl hexanol, 2-ethyl, 3-propyl acrolein (EPA), and 2-ethylhexanal (EHA) is disclosed. The crude alcohol stream is first separated into a first stream of primarily 2-EH, a second stream of primarily EPA and 2-EH collectively, and a third stream of primarily 2-EH and EHA collectively. The second stream and the third stream are combined to form a combined stream. The combined stream is processed further to form a first product stream comprising primarily 2-EH and a second product stream comprising primarily, 2-EH, EHA, and EPA collectively.

Abstract: A process for preparing a gasoline octane boosting composition, including contacting a pyrolysis oil with a non-thermal oxygen plasma to produce an oxidized pyrolysis oil; and mixing the oxidized pyrolysis oil with a gasoline additive to produce the gasoline octane boosting composition. The gasoline octane boosting composition can be used in a gasoline blend.
