  • Publication number: 20140309469
    Abstract: An integrated process for producing gasoline blending components and aromatic hydrocarbons which comprises: (a) contacting a lower alkane feed with an aromatic hydrocarbon conversion catalyst to produce an aromatic reaction product mixture which is comprised of benzene and/or toluene and/or xylene, C9 aromatic products, C10 aromatic products including naphthalene and, optionally, C11+ aromatic products, (b) separating and recovering the aromatic reaction product mixture, (c) separating and recovering benzene, (d) optionally separating recovering toluene and/or xylene, and (e) separating and recovering the C9 aromatic products and the C10 aromatic products which boil at a lower temperature than naphthalene from the naphthalene and the C10 aromatic reaction products which boil at a higher temperature than naphthalene and any C11+ aromatic products.

  • Patent number: 8168838
    Abstract: A process for the preparation of a synthetic predominantly single carbon number hydrocarbon fluid comprises the steps of: contacting an alpha olefin having a carbon number of 4 to 30 with a single site catalyst under conditions effective to produce reactive hydrocarbon oligomers that contain reactive double bonds and comprising predominantly dimers, trimers, and tetramers wherein at least 10 weight percent of such reactive hydrocarbon oligomers at least one of trimers and tetramers; separating at least one of said trimers and tetramers in said reactive hydrocarbon oligomers; dimerizing said separated one of said trimers tetramers by contacting said separated one of said trimers or tetramers with a dimerization catalyst thereby producing an unsaturated synthetic hydrocarbon fluid; and contacting said unsaturated synthetic hydrocarbon fluid with hydrogen in the presence of a hydrogenation catalyst thereby producing a synthetic hydrocarbon fluid having predominantly single carbon number.

  • Publication number: 20030168382
    Abstract: An atmospheric distillate stream is combined with a calculated amount of lubricant extract stream. This well-mixed stream is then hydrotreated to yield a non-carcinogenic, high aromatic process oil. A desired level of high aromatic lubricant product streams and having the desired solvency properties is achieved by varying the feed stream ratio and hydrotreating conditions.
