Effective solutions to the problems of the vacuum residue hydrodesulfurization unit equipped with the fixed bed reactors, such as a hot spot, pressure-drop buildup, and catalyst deactivation by coke fouling, were discussed. Improving liquid distribution can prevent hot spot occurrence. Dispersing inorganic solids throughout the reactors can control a pressure-drop increase in the first bed. For a high conversion operation, controlling the conversion in each bed can minimize the coke deactivation in the fourth bed.

Stability of common polymers, and consequently, thermal degradation of mercaptide molecules ean be also carried out with the mercaptide dissolved into a polymeric medium. In this case, a finely dispersed inorganic solid phase, embedded in polymer, is generated. Materials based on clusters confined in polymeric matrices are called nanocomposites [Mayer, 1998 Caseri, 2000]. Both semiconductor-polymer and metal-polymer nanocomposites have unique functional properties that can be exploited for applications in several advanced technological fields (e.g., optics, nonlinear optics, magnetooptics, photonics, optoelectronics) [Caseri, 2000].

Biodegradable polymer nanocomposites have emerged as a new class of materials and attracted considerable interest and investment in research and development worldwide [76-79]. This is largely due to their new and often much improved mechanical, thermal, electrical and optical properties as compared to their macro- and micro- coimterparts. In general, polymer nanocomposites are made by dispersing inorganic or organic nanoparticles into either a thermoplastic or thermoset polymer [80-85]. Nanoparticles can be three-dimensional spherical and polyhedral nanoparticles (e.g.. 

Nanocomposites (10 m) Polymer nanocomposites usually comprise the composites of polymers with dispersed inorganic nanofillers. The nanofiller can be an insulator, a semiconductor, or a metal, and it can have spherical, cylindrical, or flake shapes. The polymer (matrix) can be conductive or nonconductive in nature.
