Summary:The present invention relates to an adsorbent with excellent moldability which is capable of removing hydrogen sulfide, siloxane, etc. with high efficiency by using fumed silica or silica gel, ammonia water, and a polyferric sulfate solution, and a method for producing the same. The method for producing an adsorbent with excellent moldability according to the present invention comprises the steps of: mixing fumed silica, silica gel or a mixture thereof with ammonia water at a weight ratio of 1:20 to 1:60 while titrating and stirring polyferric sulfate until a pH of 6-9 is reached 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. La présente invention concerne un adsorbant ayant une excellente aptitude au moulage qui est capable d'éliminer le sulfure d'hydrogène, le siloxane, etc, avec une efficacité élevée en utilisant de la silice fumée ou du gel de silice, de l'ammoniaque et une solution de sulfate polyferrique. L'invention concerne également le procédé de production d'un tel adsorbant. Le procédé de production d'un adsorbant ayant une excellente aptitude au moulage selon la présente invention comprend les étapes consistant à: mélanger de la silice fumée, du gel de silice ou un mélange de ceux-ci avec de l'ammoniaque selon un rapport pondéral de 1:20 à 1:60 pendant le titrage et le brassage du sulfate polyferrique jusqu'à ce qu'un pH de 6-9 soit atteint pour produire un précipité; séparer le précipité de phase solide et le liquide contenu dans le mélange; laver le précipité avec de l'eau de lavage; et sécher le précipité. 본 발명은 흄드 실리카 또는 실리카겔과, 암모니아수 및 폴리황산철 용액을 이용하여 황화수소, 실록산 등을 고효율로 제거할 수 있는 성형성이 우수한 흡착제 및 이의 제조방법에 관한 것이다. 본 발명에 따른 성형성이 우수한 흡착제의 제조방법은, 흄드 실리카, 실리카겔 또는 이들의 혼합물과 암모니아수를 1 : 20 내지 1 : 60의 중량비로 혼합하면서 혼합액의 pH가 6~9에 도달될 때까지 폴리황산철을 적정하면서 교반하여 침전물을 생성하는 단계와; 혼합물에 포함된 고상의 침전물과 액체를 분리하는 단계와; 침전물을 세정수로 세척하는 단계 및 침전물을 건조하는 단계를 포함하는 것을 특징으로 한다.
