  • Activated carbon for separation of fluids by adsorption and method for its preparation
    Patent number: 5726118
    Abstract: An activated carbon composition of matter is disclosed comprising a mixture of: (a) a first activated carbon having a plurality of pore sizes, pore volumes and pore surface areas sufficient to selectively adsorb fluids having molecular diameters from about 4 Angstroms to about 4,000 Angstroms; and (b) a second activated carbon having a plurality of pore sizes, pore volumes, and pore surface areas to selectively adsorb fluids having molecular diameters from about 4 Angstroms to about 4,000 Angstroms. The pore size distribution of pores in the second activated carbon that adsorbs fluids having molecular diameters from about 4 Angstroms to about 15 Angstroms is greater than that of the first activated carbon. The second activated carbon is present in an amount sufficient to provide a methane working capacity of the mixture greater than the methane working capacity of the first activated carbon.
