ABSTRACT:
A multistage technique for converting olefins to heavier hydrocarbons including a sorption prefractionation unit for separating olefinic feedstock into a sorbate stream rich in liquified olefins and a vapor stream rich in light olefins; a first stage catalytic reactor unit for oligomerizing olefins from the sorbate stream including means for maintaining the first stage at elevated pressure and predetermined temperature for producing substantially linear aliphatic hydrocarbons; a second stage catalytic reactor unit for oligomerizing light olefin including means for maintaining the second stage under high severity conditions at substantially higher temperature than the first stage; and a product fractionation unit for separating effluent from the first and second stages to separate and recover heavy hydrocarbon product and a sorbent recycle fraction. The sorbent fraction is recycled to the sorption prefractionation unit for contacting olefinic feedstock with the recycled sorbent. Unconverted second stage olefins may be also sorbed by the recycled fraction for further reaction.
