    摘要： In a hydrocarbon upgrading process, a hydrocarbon feed is treated in at least one of a steam cracker, catalytic cracker, coker, hydrocracker, and reformer under suitable conditions to produce a first stream comprising olefinic and aromatic hydrocarbons. A second stream composed mainly of C4 to C12+ olefinic and aromatic hydrocarbons is recovered from the first stream and blended said second stream with a residual fraction from a steam cracker or an atmospheric or vacuum distillation unit to produce a third stream. The third stream is then catalytically pyrolyzed in a reactor under conditions effective to produce a fourth stream having an increased benzene and/or toluene content compared with said second stream and a C3-olefin by-product. The C3-olefin by-product is recovered and benzene and/or toluene are recovered from the fourth stream.

    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.
