  • Patent number: 8481796
    Abstract: A hydrocarbon composition that comprises species of at least 3 different carbon numbers, at least about 95 wt % non-normal hydrocarbons, no greater than 1000 wppm aromatics, no greater than 10 wt % naphthenes, and also has a certain boiling point range; and a process for making the hydrocarbon composition.
    Type: Grant
    Filed: January 27, 2006
    Date of Patent: July 9, 2013
    Assignee: ExxonMobil Chemical Patents Inc.

  • Patent number: 7741526
    Abstract: A feedstock containing at least 1 wt % butenes, at least 1 wt % pentenes, at least 1 wt % hexenes, at least 10 wppm C4 dienes, at least 10 wppm C5 dienes, and optionally at least 10 wppm C6 dienes can be selectively hydrogenated over a catalyst (e.g., a noble metal) to form a stream containing 100 wppm to 4000 wppm total dienes. The hydrogenated stream, and an olefinic recycle stream having less than 10 wt. % C1+ moieties, can be contacted with a molecular sieve catalyst, e.g., at a recycle to feed ratio between 0.1 and 3.0, at a WHSV of at least 1.0 based on olefin in the feed, and at a reactor ?T no greater than 40° F. (22° C.), thus forming a reaction product that can then be separated into a distillate, e.g., having from 1 wt % to 30 wt % non-normal C9 olefins, and the aforementioned olefinic recycle stream.

  • Patent number: 7692049
    Abstract: A hydrocarbon composition comprises at least 90 wt. % of C9 to C20 non-normal olefins, non-normal saturates or combinations thereof based on the weight of the hydrocarbon composition, at least 2 wt. % and not greater than 25 wt. % of C9 hydrocarbons based on the weight of the hydrocarbon composition, and less than 15 wt. % of C17+ hydrocarbons based on the weight of the hydrocarbon composition, wherein said hydrocarbon composition has a specific gravity at 15° C. of at least 0.730 and less than 0.775. The composition is produced by oligomerization of at least one C3 to C8 olefin and an olefinic recycle stream containing no more than 10 wt. % of C10+ non-normal olefins. The composition is useful in producing fuel blends, such as jet fuel and diesel fuel.

  • Patent number: 7678953
    Abstract: A process for producing a hydrocarbon composition that comprises contacting a feed stream, that comprises at least one C3 to C8 olefin, and an olefinic recycle stream, that comprises a first olefinic recycle stream and no more than 10 wt % of C10+ non-normal olefins, with a molecular sieve catalyst in a reaction zone under olefin oligomerization conditions producing an oligomerization effluent stream; separating the oligomerization effluent stream to produce a first olefinic stream, that has a weight ratio of C4?/(C5-C8) molecules from about 0.8 to about 1.2 times the weight ratio of C4?/(C5-C8) molecules found in the oligomerization effluent stream, and a first hydrocarbon product stream, that comprises at least 1 wt % and no more than 30 wt % of C9 non-normal olefin; and splitting the first olefinic stream to produce the first olefinic recycle stream and a first purge stream.
