Abstract
In the present disclosure, a heterogeneous nickel-based oligomerization catalyst in which nickel in the form of single atom is loaded on an Al-mesoporous silicate support by ion exchange and a method for producing the same, and a method for oligomerizing light olefins, specifically C4 olefins using the catalyst are described.
Claims20
An oligomerization method comprising:
- providing a light olefin-containing feedstock;
- performing an oligomerization reaction of the light olefin-containing feedstock in presence of a heterogeneous catalyst at a temperature of 150 to 350° C. and a pressure of 10 to 50 bar;
- and
- recovering an olefin having a higher number of carbon atoms than the light olefin from an oligomerized product,
- wherein the heterogeneous catalyst is a heterogeneous oligomerization catalyst in which Ni in a form of single atom is supported on an Al-mesoporous silicate having a Si/Al atomic ratio in a range of 5 to 100 as a support, and
- wherein an amount of nickel supported in the heterogeneous oligomerization catalyst is in a range of 0.1% to 10% by weight.
