Abstract
A method of deactivate a catalyst system is described. The method may include contacting a reactor effluent comprising a catalyst system, an oligomerized olefin, and diluent with a kill agent to at least partially deactivate the catalyst system, separating the reactor effluent into one or more first streams comprising oligomerized olefin and diluent, the one or more first streams being substantially devoid of the at least partially deactivated catalyst, and a second stream comprising the deactivated catalyst; and contacting the second stream with a quench agent.
Claims26
A method comprising:
- a) contacting a reactor effluent comprising a catalyst system comprising a chromium compound, an oligomerized olefin, and diluent with a kill agent to at least partially deactivate the catalyst system, wherein the oligomerized olefin comprises at least 70 weight percent trimer;
- b) separating the reactor effluent into
- i) one or more first streams comprising oligomerized olefin, diluent, or combinations thereof, the one or more first streams being substantially devoid of the at least partially deactivated catalyst, and
- ii) a second stream comprising the deactivated catalyst;
- and
- c) contacting the second stream with a quench agent, wherein the quench agent comprises a compound selected from the group consisting of an amine, an alcohol, and any combination thereof.
A method comprising:
- a) contacting a catalyst system comprising a chromium compound, ethylene, and a diluent;
- b) producing a trimerization product comprising 1-hexene in a reactor;
- c) removing a reactor effluent comprising the catalyst system, ethylene, the trimerization product, and diluent, from the reactor, wherein the trimerization product comprises at least 70 weight percent trimer;
- d) contacting the reactor effluent with a kill agent to at least partially deactivate the catalyst system;
- e) distilling the reactor effluent into
- i) one or more first streams comprising ethylene, 1-hexene, diluent, or any combination thereof, the one or more streams being substantially devoid of deactivated catalyst, and
- ii) a second stream comprising the deactivated catalyst system;
- and
- f) contacting the second stream with a quench agent, wherein the quench agent comprises a compound selected from the group consisting of an amine, an alcohol, and any combination thereof.
