Two series of alumina-based catalysts impregnated with alkali metal oxides are investigated for CS2 hydrolysis in an integral reactor at temperatures ranging from 80 to 160℃, gas space velocity of 10000 h-1 and atmospheric pressure. It turns out that the active precursor significantly affects the activity of catalyst. There is an optimum active species loading for the most efficient catalysts. CS2 conversion in the Presence of GC4 can reach more than 98% at 160℃. A mechanism involving the panicipation of basic sites is postulated for the reaction.
