Abstract

Abstract: Hydrolysis rate of carbonyl sulphide was determined in a bubble reactor at 20-50℃, sodium hydroxide concentration 1. 3130-4. 4038 mol/L and atmospheric pressure. The first-order rate expression for the hydrolysis of carbonyl sulphide is Ink1 =27.90 - 7168/T + 0.56I where, Ncos,Hcos,pcos,i are absorption rate, solubility coefficient and partial pressure at interface of COS respectively. The constant ki is first-order rate-constant of forward reaction and I is ionic strength for initial concentration of NaOH. The apparent activation energy is 59.63 kJ/mol.
