ADSORBENT OF LATENT-HEAT STORAGE TYPE FOR CANISTER AND PROCESS FOR PRODUCING THE SAME

摘要

An adsorbent of the latent-heat storage type for canisters which can be effectively inhibited from changing in temperature due to the heat of absorption/desorption and has a high butane working capacity; a process for producing the adsorbent; and a canister employing the adsorbent of the laten t- heat storage type for canisters. The adsorbent of the latent-heat storage ty pe for canisters comprises: an adsorbent adsorbing a fuel vapor; and a heat- storage material comprising a microencapsulated phase-changing substance whi ch absorbs or releases latent heat depending on temperatures.
