Figure 4. The number cobalt particles and surface area of the particles calculated from TDFNR spectra.
(a) Total amount of metallic cobalt particles per mg of cobalt (Np mgCo−1) produced in the 3 studied catalysts. (b) Number of particles involved in the blocking temperature ranges (particles size ranges) determined from the 59Co NMR technique. (c) Total cobalt particles' surface area per the mass of cobalt (NSA mgCo−1) exposed for the FT reaction. (d) Particles surface area involved in each of the blocking temperature ranges (sizes).
