Abstract
Disclosed is oligomerization of ethylene to form 1-hexene in combination with aromatization of the 1-hexene formed by oligomerization, to form benzene.
Claims19
A method comprising:
- contacting, in an oligomerization reactor, ethylene and an oligomerization catalyst to yield an oligomerization reactor effluent comprising 1-hexene;
- flowing at least a portion of 1-hexene recovered from the oligomerization reactor effluent to a hydrogenation reactor;
- contacting, in the hydrogenation reactor, the at least a portion of 1-hexene with a hydrogenation catalyst to yield a hydrogenation reactor effluent comprising hexanes;
- recovering hexanes from the hydrogenation reactor effluent;
- and
- contacting, in an aromatization reactor, hexanes recovered from the hydrogenation reactor effluent with an aromatization catalyst to yield an aromatization reactor effluent comprising benzene.

A system comprising:
- an oligomerization reactor configured to contact ethylene with an oligomerization catalyst to yield an oligomerization reactor effluent comprising 1-hexene;
- a hydrogenation reactor configured to contact 1-hexene recovered from the oligomerization reactor effluent with a hydrogenation catalyst to yield an aromatization feed comprising hexane;
- and
- an aromatization reactor configured to contact the aromatization feed with an aromatization catalyst to yield an aromatization reactor effluent comprising benzene.
