  • Process of removing contaminants from an olefin stream using extractive distillation
    Patent number: 6559248
    Abstract: Disclosed is a method of purifying olefin containing oxygenate contaminants. The method incorporates the use of extractive distillation. Under the appropriate conditions, olefins containing very low levels of oxygenate contaminants can be recovered.
    Type: Grant

  • Olefin oligomerization
    Publication number: 20020111523
    Abstract: This invention is to a method of oligomerizing an olefin feed stream. The olefin feed stream contains at least one C2 to C12 olefin to obtain an olefin feed stream and has less than 1,000 ppm by weight oxygenated hydrocarbon. The olefin is oligomerized by contacting with an acid based oligomerization catalyst.

  • Production of olefin dimers and oligomers
    Publication number: 20020103406
    Abstract: Disclosed is an olefin containing stream from an oxygenate to olefin process, and a process for making olefin dimer and oligomer product from the olefin containing stream using a nickel based oligomerization catalyst. The dimer/oligomer product is optionally converted to hydroformylated product. The olefin containing stream that is used to make the higher olefin product has low levels of impurities including nitrogen, sulfur and/or chlorine.
