An object of the present invention is to provide a porous silica particle with the small specific surface area and the large pore volume, a method for producing the same, and a cosmetic containing the porous silica particle with such characteristics as the texture improver. The porous silica particle according to the present invention has a structure sparsely packed with silica microparticles. The mean particle diameter is 0.5 to 25 m, the specific surface area measured by the BET method is 5 to 60 m^(2)/cm^(3), and the pore volume is 0.35 to 2.0 ml/g. In the pore size distribution of the porous silica particles (X axis: pore diameter, Y axis: value obtained by differentiating the pore volume by the pore diameter), the most frequent pore diameter (D_(m)) satisfies 100 < D_(m) < 4000 [nm].

The invention relates to a method for optimizing layered catalytic processes. This is accomplished by testing various catalysts with a compound found in a feedstock to be tested, to determine the facility of the catalyst in hydrogenating, hydrosulfurizing, or hydrodenitrogenating the molecule, and hence the feedstock. in a preferred embodiment, the Double Bond Equivalence of the feedstock and molecule are determined, and catalysts are pre-selected based upon their known ability to work with materials of this DBE value.
