Effect of H2 in CO Feed Gas on Carbonylation of Methanol to Acetic Acid over Ir-Ru Catalysts

Article Preview

Abstract:

Effect of the minor H2 presence in CO feed gas on the carbonylation of methanol to acetic acid over homogeneous Ir-Ru catalysts was studied. The results indicated that the carbonylation reaction rate would be decreased with the increasing of H2 content in CO feed gas. The process of CO migratory insertion was inhibited with the decrease of CO partial pressure in feed gas. With the increasing of H2 content in CO feed gas, CH4 composition distribution in gas byproducts was increased while that of CO2 was decreased. The yield of propionic acid in liquid products was increased. The occurrence extent of hydrogenated side reactions was affected due to minor H2 presence.
