Abstract

La présente invention concerne un charbon actif ayant des MC adhérentes ne pouvant subir une augmentation ou une diminution de température lors de l'adsorption/désorption d'un gaz de combustible évaporé, ayant d'excellentes performances d'adsorption/désorption, pouvant maintenir stable les performances d'adsorption/désorption et étant moins susceptible de séparer les MC et l'adsorbant ; un procédé de production du charbon actif ; et un réservoir utilisant le charbon actif. Le charbon actif ayant des microcapsules adhérentes comprend un charbon actif et, adhérées à celui-ci, des microcapsules ayant chacune, renfermée dans celles-ci, une substance qui absorbe et émet de la chaleur lors du changement de phase. Le charbon actif ayant de telles microcapsules adhérées à celui-ci est obtenu en utilisant en tant que liant une composition aqueuse obtenue en diluant avec de l'eau un mélange de résine liquide comprenant une émulsion aqueuse (A) qui forme un film lors de l'évaporation d'eau de façon à avoir des propriétés adhésives et une résine liquide de réticulation (B).
