Abstract: A method of producing alcohol alkoxylates comprising contacting a hydrocarbon mixture with a hydroformylation catalyst under hydroformylation conditions to form a product mixture comprising one or more alcohols and formate esters; treating the product mixture to reduce the concentration of formate esters to produce an alcohol stream; and contacting the alcohol stream and an epoxide with a potassium hydroxide catalyst under alkoxylation conditions to produce one or more alcohol alkoxylates.

Abstract: A process for producing alpha-olefins comprising contacting an ethylene feed with an oligomerization catalyst system in an oligomerization reaction zone under oligomerization reaction conditions to produce a product stream comprising alpha-olefins wherein the catalyst system comprises an iron-ligand complex and a co-catalyst and the residence time in the reaction zone is in the range of from 2 to 40 minutes.

Abstract: The invention provides a process for producing alpha-olefins comprising: a) contacting an ethylene feed with an oligomerization catalyst system, the catalyst system comprising a metal-ligand catalyst and a co-catalyst, in an oligomerization reaction zone under oligomerization conditions to produce a product stream comprising alpha-olefins; b) withdrawing the product stream from the oligomerization reaction zone wherein the product stream further comprises oligomerization catalyst system; c) contacting the product stream with a catalyst deactivating agent to form a deactivated product stream that contains deactivated catalyst components; and d) heating the deactivated product stream to separate one or more components from the deactivated product stream.

Abstract: Prior to reaction in an isomerization unit, the feed may be purified by contact with a composition comprising an alumina based catalyst including Group I or Group II cations or combinations thereof in a range from about 0 wt % to about 20 wt % Group I or Group II cations. In some embodiments, the alumina based catalyst has one or more of the following properties; pore volume in pores of less than 70 Å pore diameter of less than about 15% of Total Pore Volume: a pore volume in pores of greater than 350 Å pore diameter of less than 10% of Total Pore Volume; a median pore diameter by volume of less than 120 Å; a water pore volume of less than 1.10 cc/g;: and a surface area of greater than 160 m2/g.
