  • Patent number: 6429349
    Abstract: Methods and apparatus that are used in an alkylation reactor system for adding low purity isopentane to alkylation reactor feed to block formation of isopentane, resulting in high incremental isopentane conversion and minimal octane and C5+ yield loss, and low acid consumption from C6+ isoparaffins with superior yields.
    Type: Grant
    Filed: August 12, 1996
    Date of Patent: August 6, 2002
    Assignee: BP Corporation North America Inc.
    Inventors: Lewis E. Grimes, R. L. Mehlberg, V. J. Kwasniewski, James B. Young, John V. Bartels
  • Patent number: 5364979
    Abstract: A catalyzed, continuous vapor phase process to convert a C.sub.2 or higher alcohol and, optionally, one or more C.sub.1 or higher alcohols, for example methanol and ethanol, to a mixture containing at least one higher molecular weight alcohol, for example, isobutanol, over a catalyst which is essentially magnesium oxide. The process also may have a lower aldehyde and/or ketone in the feed.
    Type: Grant
    Filed: January 5, 1994
    Date of Patent: November 15, 1994
    Assignee: Amoco Corporation
    Inventors: Cecelia A. Radlowski, Gary P. Hagen, Lewis E. Grimes, David F. Tatterson
  • Patent number: 5015799
    Abstract: A method for converting methane to higher molecular weight hydrocarbons wherein hot oxidative coupling reactor effluent is briefly contacted with a C.sub.2 to C.sub.20 alkane quench material to remove part of the heat contained in the raw reactor effluent, and is then further quenched by thermal quenching means to achieve a temperature which discourages retrograde reactions.
    Type: Grant
    Filed: July 6, 1989
    Date of Patent: May 14, 1991
    Assignee: Amoco Corporation
