The present invention relates to an adsorbent excellent in moldability and capable of removing hydrogen sulfide, siloxane, and the like with high efficiency using fumed silica or silica gel, aqueous ammonia solution, and an aqueous solution of polyphosphorus, and a method for producing the same. The method for producing an adsorbent excellent in moldability according to the present invention is a method for producing an adsorbent excellent in moldability, comprising mixing fumed silica, silica gel or a mixture thereof with ammonia water at a weight ratio of 1:20 to 1:60, Stirring the iron sulfate with an appropriate amount to produce a precipitate; Separating the solid phase precipitate and liquid contained in the mixture; Washing the precipitate with washing water, and drying the precipitate. |
