Anti-poisoning catalyst for hydrolysis of organic sulfur in blast furnace gas and preparation method of anti-poisoning catalyst

The invention relates to an anti-poisoning catalyst for organic sulfur hydrolysis of blast furnace gas and a preparation method of the anti-poisoning catalyst. The catalyst comprises the following components in percentage by weight: 4-12% of active component K2CO3; 2 to 5% of an active component Cs2CO3; 3-8% of a catalytic promoter MoO3; 0.5 to 2% of a catalytic promoter La2O3; 1-5% of a forming aid SiO2; and 68-89.5% of a composite metal oxide carrier Al2O3-TiO2, wherein the pore diameter of the composite metal oxide carrier Al2O3-TiO2 is in three-channel distribution. The preparation method comprises the following steps: preparing a composite metal oxide carrier, molding the composite metal oxide carrier and silicon dioxide, and impregnating the active component and a catalyst auxiliary agent to prepare the catalyst. The catalyst prepared by the invention has excellent catalytic hydrolysis activity on organic sulfur in blast furnace gas, and has lasting catalytic oxidation activity due to sulfur resistance,
