The invention concerns a process and a system for oligomerization of olefins. According to the process, feedstock containing olefins from C3 to C20, or a mixture thereof, is introduced to a catalytic distillation reactor system comprising a distillation column (27) and at least one side reactor (31, 32), where the olefins of the feedstock are contacted with a catalyst (30) for manufacturing a product containing oligomers. According to the invention, a solid oligomerization catalyst such as a zeolite is used, and the olefins are contacted with the catalyst at a temperature sufficiently high to attain oligomerization. The present process is employed in the manufacture of, e.g., intermediate distillates and lubricants. By combining the reaction and distillation steps in a single system, the energy balance of the oligomerization process can be improved substantially. |
