The key technology for adsorbed natural gas (ANG) is to manufacture an excellent adsorbent meeting the target for storing natural gas as much as compressed natural gas (CNG).The techniques of ANG by highly nanometer porous carbon used as vehicular fuel are introduced.Varied activation methods during the process for manufacturing a highly microporous carbonaceous adsorbent are reviewed.The microstructure and the briquetting methods are also produced.Finally,several crucial problems to be solved including the present relatively lower storage capacity for natural gas,the extent of the adsorption heat affecting adsorption,the production cost and the difficulty of regeneration of the adsorbents are put forward.
