  • METHOD FOR PRODUCING ALCOHOL, METHOD FOR PRODUCING HYDROGEN OR SYNTHESIS GAS USING THE METHOD FOR PRODUCING ALCOHOL, AND ALCOHOL
    Publication number: 20110172468
    Abstract: One object of the present invention is to provide a method for producing an alcohol which can produce a target alcohol containing a remarkably low content of the sulfur compound(s), and the present invention provides a method for producing an alcohol comprising a separation process which reduces the content of sulfur compound(s) in a crude alcohol containing at least the sulfur compound(s) through desulfurization treatment in which the crude alcohol is contacted with a separation membrane based on a pervaporation method, thereby a content of the sulfur composition in the crude alcohol is decreased.
