  • Mixed alcohols production from syngas
    Patent number: 4831060
    Abstract: Mixed alcohols are produced from carbon monoxide and hydrogen gases using an easily prepared catalyst/co-catalyst metal catalyst. The catalyst metals are molybdenum, tungsten or rhenium. The co-catalyst metals are cobalt, nickel or iron. The catalyst is promoted with a Fischer-Tropsch promoter like an alkali or alkaline earth series metal or a smaller amount of thorium and is further treated by sulfiding. The composition of the mixed alcohols fraction can be selected by selecting the extent of intimate contact among the catalytic components.
    Type: Grant
    Filed: June 6, 1988
    Date of Patent: May 16, 1989
    Assignee: The Dow Chemical Company
    Inventors: Rex R. Stevens, Mark M. Conway

  • Method for adjusting methanol to higher alcohol ratios
    Patent number: 4675344
    Abstract: A method for controlling the ratio of methanol to higher alcohols produced in a process for making mixed alcohols by contacting a hydrogen- and carbon monoxide-containing feed with a molybdenum- or tungsten-containing catalyst, said method comprising adjusting a concentration of a sulfur releasing substance in the feed.
