An efficient CO2 adsorbing monolith structure is obtained. The monolith is based on blended petroleum-pitch-derived carbon fibers and phenolic resin in weight ratio of 3:1. The measured CO2 adsorption capacity of the adsorbent is about 2.34-2.87 moles CO2/kg at 1 bar and 273 K. Due to its good electrical conductivity, the adsorbed CO2 can be desorbed quickly and efficiently by direct electro-thermal desorption, at the passage through the monolith of an electric current at low voltage. The measured rate of CO2 desorption of the steam activated sample FCN400a at environmental pressure is 0.273 moles/h at 393 K (18 A/6.8 V)..

Active accounts were imported to the new platform and assigned a random password by default. In order to access your account you need to access the login page and go through the Lost Password dialog (involves the system sending you an email with instructions) in order to reset your password. This step is necessary as passwords are kept in hashed form and the new platform uses modern hashing algorithms incompatible with the previous ones.
