    摘要： 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 ΔT 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.

    摘要： 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.

    摘要： In a process for producing a hydrocarbon composition, a feed comprising at least one C3 to C8 olefin and an olefinic recycle stream rich in C9− hydrocarbons is contacted with a crystalline molecular sieve catalyst having an average crystal size no greater than 0.05 micron and an alpha value between about 100 and about 600 in at least one reaction zone under olefin oligomerization conditions including an inlet temperature between about 150° C. and about 350° C., a pressure of at least 2,860 kPa and a recycle to feed weight ratio of about 0.1 to about 3.0. The contacting produces an oligomerization effluent stream, which is separated into at least a hydrocarbon product stream rich in C9+ hydrocarbons and the olefinic recycle stream.
