<p>A process and apparatus for dimerization are disclosed. The process includes introducing at least one feedstock which includes an olefin selected from the group consisting of terpenes, alpha-olefin oligomers (AOO), and related olefins and introducing at least one solid acid catalyst to the feedstock for isomerization. The initial heat of isomerization can be recovered and utilized. A first fractionation is used for evaporation of unreacted feedstock, the first fractionation process reducing a pressure of the unreacted feedstock. The concentration of reacting olefin during the isomerization is adjusted via an active recycle protocol. This process produces dimerized products and suppresses formation of oligomers of the olefin, and also enables utilizing a lowered reaction temperature during the isomerization to extend the lifetime of the catalyst. A dimerized product having less than 5 wt. % total of the oligomers of the olefin combined is produced.</p> |
