Adsorbent production method and adsorbent for removing trace components in hydrocarbon oil

摘要

PPROBLEM TO BE SOLVED: To provide an adsorbent which is made of hard active carbon having a high specific surface area and a high bulk density and efficiently adsorbs/removes microingredients in hydrocarbon oil, a method for producing the adsorbent, a method for removing the microingredients in the hydrocarbon oil using the adsorbent, and a fuel battery system. PSOLUTION: The method for producing the adsorbent includes the molding carbonization treatment process in which a binder made of saccharide is added into vegetable biomass or a vegetable biomass preliminary carbonization treatment product, and the mixture, after being kneaded and molded, is carbonized to obtain a molded carbonization treatment product and the activation treatment process in which the obtained molded carbonization treatment product, after being impregnated with the binder, is activated to obtain a molded activation treatment product. The adsorbent for removing the microingredients in the hydrocarbon oil containing an activation treatment product which is obtained by the above method and has a specific surface area of at least 600 mSP2/SP/g and a mean micropore width of at least 1.0 nm, the method for removing the mictoingredients in the hydrocarbon oil using the adsorbent, or the fuel battery system provided with the adsorbent are disclosed.
