  • Catalyst stability in carbonylation processes
    Patent number: 9193657
    Abstract: A method for stabilizing a carbonylation catalyst with carbon monoxide recovered from a gaseous stream derived from a carbonylation reaction. The carbon monoxide enriched stream is fed downstream of the carbonylation reactor, preferably to a flasher or light ends column, to enhance catalyst stability throughout the process.
    Type: Grant
    Filed: August 17, 2012
    Date of Patent: November 24, 2015
    Assignee: Celanese International Corporation
    Inventors: Mark O. Scates, Ronald D. Shaver, Gregory Blanchard
