Alpha-olefin production
Abstract
Abstract ETHYLENE IS CONVERTED TO LINEAR A-OLEFINS OF A SELECTED RANGE OF CARBON ATOMS BY (1) OLIGOMERIZING ETHYLENE TO LINEAR A-OLEFINS, (2) SEPARATING THE LINEAR A-OLEFINS INTO A LOWER A-OLEFIN FRACTION OF THE SELECTED RANGE OF CARBON ATOMS AND A HIGHER A-OLEFIN FRACTION, (3) RECOVERING THE LOWER A-OLEFIN FRACTION AS PRODUCT, (4) ISOMERIZING THE HIGHER A-OLEFIN FRACTION TO INTERNAL OLEFINS, (5) DISPROPORTIONATING THE INTERNAL OLEFINS WITH EXCESS ETHYLENE TO PRODUCE ADDITIONAL LOWER A-OLEFINS WHICH ARE RECYCLED TO PRODUCE ADDITIONAL LOWER A-OLEFINS WHICH ARE RECYCLED TO STEP 2 FOR SEPARATION. BY A PRFERRED MODIFICATION OF THE PROCESS ETHYLENE IS CONVERTED TO AN A-OLEFIN PRODUCT MIXTURE OF A CONTROLLED MOLECULAR WEIGHT RANGE AND FREE OF LOWER OLIGOMERS, E.G., DIMERS, TRIMERS, ETC.
