    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 at least part of the second stream is contacted with a catalyst in the absence of added hydrogen under reaction conditions including a temperature of about 450° C. to about 70° C. effective to dealkylate, transalkylate, crack and aromatize components of the second stream to produce a third stream having an increased benzene and/or toluene content compared with the second stream and a C3− olefin by-product. The C3− olefin by-product and a fourth stream comprising toluene are then recovered from the third stream.

    摘要： In a process for converting methane to higher hydrocarbons including aromatic hydrocarbons, a feed containing methane is contacted with a dehydrocyclization catalyst under conditions effective to convert said methane to aromatic hydrocarbons and produce a first effluent stream comprising aromatic hydrocarbons and hydrogen, wherein said first effluent stream comprises at least 5 wt % more aromatic hydrocarbons than said feed. At least part of the hydrogen from said first effluent stream is then reacted with an oxygen-containing species, such as carbon dioxide, to produce a second effluent stream having a reduced hydrogen content compared with said first effluent stream.

    摘要： There is provided a catalyst composition having improved hydrothermal stability for the catalytic cracking of a hydrocarbon feedstock to selectively produce propylene. The catalyst composition comprises a first crystalline molecular sieve selected from the group consisting of IM-5, MWW, ITH, FER, MFS, AEL, and AFO and an effective amount of a stabilization metal (copper, zirconium, or mixtures thereof) exchanged into the molecular sieve. The catalyst finds application in the cracking of naphtha and heavy hydrocarbon feedstocks. When used in the catalytic cracking of heavier hydrocarbon feedstocks, the catalyst composition preferably comprises a second molecular sieve having a pore size that is greater than the pore size of the first molecular sieve. The process is carried out by contacting a feedstock containing hydrocarbons having at least 4 carbon atoms is contacted, under catalytic cracking conditions, with the catalyst composition.
