“…It should be noted that to increase the catalyst activity it is required not only to increase the internal surface but also to create specific porous structure of the catalyst grains that provides a sufficient speed for supplying reactants to the outermost periphery of the grain surface portions and the inner discharge of them from the reaction products. For each of the catalytic process, depending on the conditions of its implementation, kinetic dependences and specific catalytic activity of the catalyst optimal porous structure may be set which provides the highest speed of the reaction (Volkova et al 2014).…”

On the basis of b-FeOOH, Fe(OA) 3 , Fe 3 O 4 iron and spherical catalysts NiO/SiO 2 , Fe 2 O 3 /SiO 2 derived from slag waste coals of heating electrical stations, the hydrogenation of model polycyclic hydrocarbon at presence of nanodimensioned catalysts antracene was studied. On the example of conversion of anthracene, it was shown that upon release of hydrogenation of the product yield and degradation of polycyclic hydrocarbons in the hydrogenation, the mentioned catalyst systems appeared to be in the following order: nanoparticles b-FeOOH, Fe(OA) 3 and Fe 3 O 4 [spherical catalysts NiO/SiO 2 , Fe 2 O 3 /SiO 2 [commercial cobalt-molybdenum catalyst. The results showed that the catalysts studied are promising catalysts for the hydrogenation of polycyclic hydrocarbons and may be used for direct coal liquefaction.

Based on the contextualization of the current problem of the worldwide oil refining industry and the need to transform heavy crude to medium distillates, gasoline and diesel, this chapter highlights the use of hydrocracking as a versatile and flexible process for the treatment of this type of crude. Herein we describe the main characteristics and challenges (deactivation due to contaminants or coke formation, control of molecular traffic and acid modulation) that a catalyst must face for its good performance in this reaction. A review of the most reported catalysts for hydrocracking processes points to zeolites and, to a lesser extent, to silica-alumina as the main solids used and highlights the lesser attention that has been given to other materials such as clay minerals that, by their very nature, offer potential interest, particularly in the context of current environmental needs and restrictions. Within this context, the fundamental characteristics of natural clay minerals are set forth, emphasizing the main methodologies used to modify them and highlighting the potential they offer as supports and as a source of acid sites for the conformation of new, potentially efficient and competitive catalysts for hydrocracking processes.
