Abstract: New sulfide metal catalysts are described, containing Ni, Mo and W, an element Z selected from Si, Al and mixtures thereof, and possibly an organic residue, obtained by sulfidation of mixed oxide precursors, also new, characterized in that they comprise an amorphous phase and a wolframite iso structural crystalline phase, the crystallinity degree of said mixed oxides being higher than 0 and lower than 100%, preferably higher than 0 and lower than 70%. The catalysts of the invention are useful as hydrotreatment catalysts, and in particular as hydrodesulfurization, hydrodenitrogenation and/or hydrodearomatization catalysts.

Abstract: A process for the production of an optically selective coating of a receiver substrate of a suitable material for solar receiver devices particularly suitable for operating at high temperatures, more specifically for receiver tubes of linear parabolic trough, which comprises: deposition of a layer reflecting infrared radiation consisting of a high-melting metal on a heated receiver substrate of a suitable material; annealing under the same temperature and pressure conditions as the deposition of the reflecting layer; deposition on the high-melting metal of one or more layers of metal-ceramic composite materials (CERMET), wherein the metal is W and the ceramic matrix is YPSZ (“Yttria-Partially Stabilized Zirconia”); deposition on the cermet of an antireflection layer; annealing under the same temperature and pressure conditions as the depositions of the cermet and antireflection layers.
