Abstract:
A method of producing a multi-modal pore distribution activated carbon is provided herein by preparing a solution comprising a polymer precursor, mixing an additional material with the polymer precursor in the solution, cross-linking the polymer precursor with the additional material mixed therein, carbonizing the mixture of the polymer precursor and the additional material, and activating the carbonized mixture to form a multi-modal pore distribution activated carbon. The multi-modal pore distribution activated carbon can include pores less than 20 Å and greater than 30 Å or 500 Å depending upon the sorption properties desired, wherein the pore distribution of the activated carbon can be tailored to provide predetermined kinetics and/or gaseous constituent equilibrium isotherms.
