| Whole grain kernels of hard red winter wheat (HRW) and corn are potentially viable feedstocks for producing activated carbons with high surface areas and pore volumes. These activated carbons have been obtained by the physical activation, i.e., reaction, of grain charcoals generated by a single-stage as well as a two-stage pyrolytic process, at 850;The pore structures and the fractal nature of the pore-solid interfaces of charcoals obtained from both corn and HRW were investigated through small-angle X-ray scattering on length scales from approximately 10 to 10,000 A. The scattered intensity, I(q), for either type of charcoal is proportional to q... |
