  • Process for reducing the benzene content of gasoline by alkylating benzene using a lower olefin in the presence of a paraffinic diluent
    Patent number: 9834493
    Abstract: A process for reducing the benzene content of gasoline stream, such as a reformate or light naphtha, comprises alkylating the gasoline stream in a reaction zone with an olefin alkylating agent. A paraffinic stream comprising C5 to ClO paraffins is fed to the inlet of the alkylation reaction zone.
    Type: Grant
    Filed: February 7, 2011
    Date of Patent: December 5, 2017

  • Process for reducing the benzene content of gasoline
    Patent number: 9598330
    Abstract: A process is described for alkylating benzene contained in a refinery gasoline stream, in which the refinery gasoline stream is contacted with an alkylating agent comprising one or more C2 to C5 olefins in an alkylation reaction zone under alkylation conditions to produce an alkylated effluent. The alkylation reaction zone comprises at least a first alkylation reaction stage and a second alkylation reaction stage and a portion of said alkylating agent is fed to each of said first and second alkylation reaction stages so that, although the molar ratio of alkylatable aromatic to alkylating agent in the total feed to the alkylation reaction zone is less than 1, the molar ratio of alkylatable aromatic to alkylating agent at the inlet of each of the first and second alkylation reaction stages is at least 1.0.
