This invention covers a process for dimerizing of isobutylene to Iso-octene and unique configuration is being disclosed, where the Feed is diluted to low level with recycle which has essentially no Iso-octene, dual catalyst system, new selectivator (IPA) and successive catalyst stages if needed to enhance the conversion. The process is very selective and provides higher isobutylene conversion. Additionally the invention also covers the hydrogenation of olefins to Paraffin, Iso-octene to Iso-octane product under moderate conditions and with dual or single catalyst system.
