The surface characteristics of the MK10 and BMK10 catalysts are shown in Table 1. The surface area, total pore volume, and average pore diameter decreased as barium was loaded. The diameter of the MK10 molecule was approximately 61.566 Å, which suggested the possible inclusion of the mesopores of the support. In turn, this change decreased the surface area and pore diameter. Similarly, a slight drop in the surface area was recorded during mixed oxide loading onto alumina, as reported by Amani et al. [24]. The possibility of barium multilayer formation on the support surface during metal loading could not be excluded. The partial blockage of the pores by the multilayer dispersion of metals decreased the total surface area [25] and [26].
