Abstract
The present invention provides an evaporated fuel gas adsorbent, an evaporated fuel gas trapping apparatus that uses the adsorbent, an activated carbon, and a process for producing the activated carbon. The evaporated fuel gas adsorbent is capable of improving adsorptivity and desorptivity by reliably preventing a temperature rise and a temperature fall caused by heat generated in response to the adsorption and desorption of evaporated fuel gas, is capable of achieving a size reduction of the device, and is capable of being easily produced. The activated carbon has high mechanical strength and high abrasive resistance, has many pores suitable to adsorb an organic solvent, especially, evaporated fuel gas, and has a high packing density. The activated-carbon producing process is industrially advantageous.
