The industrialized hydrolysis catalyst is mainly gamma-Al2O3The sulfur resistance of the base-supported catalyst is poor, and the activity of the catalyst is reduced during operation. Hydrolysate H2S can be oxidized on the surface of the catalyst under the action of oxygen to generate elemental sulfur and sulfate, which not only poisons active components, but also blocks diffusion channels of reactants and products, and is the main reason for reducing the activity of the catalyst.
