of alcohol streams bearing any initial sulfur load in a preferred embodiment of the invention the alcohol stream to be treated includes at least 1 ppm sulfur compounds at least 2 ppm sulfur compounds 3 ppm sulfur compounds at least 4 ppm sulfur compounds at least 5 ppm sulfur compounds at least 6 ppm sulfur compounds at least 7 ppm sulfur compounds at least 8 ppm sulfur compounds at least 9 ppm sulfur compounds at least 10 ppm sulfur compounds at least 11 ppm sulfur compounds and at least 12 ppm sulfur compounds methods taught herein may reduce the amount of sulfur compounds in an alcohol stream to at or below a desired level in various embodiments of the invention for example the amount of sulfur compounds is reduced to no more than 4 ppm no more than 3 ppm no more than 2 ppm no more than 1 ppm and no more than 0 5 ppm sulfur compounds may be included in an alcohol stream for a variety of reasons and the specific mechanism by which a sulfur compound has been introduced to an alcohol stream may not be relevant to determination of the way in which it is removed sulfur compounds may be introduced to an ethanol stream for example during production of an ethanol stream from corn products in a.
