REMOVAL METHOD OF SULFUR COMPOUNDS FROM ALCOHOL CAPABLE OF EFFECTIVELY RECYCLING ALCOHOL BY INCLUDING A REMOVING PROCESS OF THE SULFUR COMPOUNDS

摘要

PURPOSE: A removal method of sulfide from alcohol is provided to reduce environmental load by increasing recycling rate of absorbers in which sulfur compound is saturation absorbed.;CONSTITUTION: A removal method of sulfide from alcohol comprises the following steps: absorbing and eliminating sulfur compounds in the alcohol by contacting the alcohol with an absorber which includes silver; and attaching and detaching the sulfur compounds which is adsorbed in the absorber by increasing the temperature of the absorber. The removal method enables repeated used of the absorber by eliminating the sulfur from the absorber. The sulfur compound is dimethyl sulfide.;COPYRIGHT KIPO 2012
