NOVELTY - Desulfurizing agent comprises high molecular porous microsphere, non-ionic surfactant, zinc oxide, graphene oxide, pre-gelatinized starch and hydrophobic agent. USE - The desulfurizing agent is useful for gas well of mouth group (claimed). ADVANTAGE - The desulfurizing agent: has good hydrophobicity, can avoid the influence of water on the adsorption effect and improve the desulfurization effect. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing the desulfurizing agent, comprising (i) placing the pregelatinized starch into the stirring tank, adding water under the stirring condition of 1000-1500 rpm, the weight ratio of pregelatinized starch and water is 1-3:20, mixing uniformly to obtain the mixed solution I; (ii) placing zinc oxide into the mixed solution I, improving the stirring speed to 2000 rpm, stirring for 20-30 minutes, then adding graphene oxide, non-ionic surfactant and hydrophobic agent into the stirring tank, continuously stirring for 30-40 minutes to obtain the mixed solution II; (iii) adding macromolecule porous microsphere into the mixed solution II, stirring for 60-80 minutes under the condition of3 00-500 rpm to obtain the mixed solution III; (iv) filtering the mixed solution III, collecting precipitate, drying the precipitate under the condition of 80-90 degrees C.
