摘要: A problem is to provide a formed adsorber having excellent adsorption and desorption performance for fuel vapor (in particular, n-butane) of a wide concentration range from a low concentration to a high concentration.
A formed product including activated carbon fiber, granular activated carbon, and a binder is prepared. A weight ratio of the activated carbon fiber to the granular activated carbon is 5 to 95 parts by weight of the activated carbon fiber to 95 to 5 parts by weight of the granular activated carbon, in a total weight of the activated carbon fiber and the granular activated carbon, a content ratio of the binder in the formed adsorber is 0.3 to 20 parts by weight of the binder to 100 parts by weight of the activated carbon fiber and the granular activated carbon, the granular activated carbon has a total pore volume ranging from 0.90 to 2.50 cm3/g, and the activated carbon fiber has a total pore volume ranging from 0.50 to 1.20 cm3/g.
