Patent ID: 8128805

Claim:
Catalyst for the hydrogenation, hydro-isomerisation, hydrocracking and/or hydrodesulfurisation, of hydrocarbon feedstocks, said catalyst having a dispersion degree of at least 0.2, said catalyst consisting of a substantially binder free bead type support material obtained through a sol-gel method comprising an addition of an aqueous sol of inorganic salts of aluminum and silicon, comprising dispersed therein crystalline molecular sieve material, through an oil-phase to an alkaline water phase, and a catalytically active component selected from precious metals, the support consisting of 5 to 60 wt. % of at least one crystalline molecular sieve material and 40 to 95 wt. % of non-crystalline, non-zeolitic silica-alumina, the support having Bronsted acidity of at least 50 μmol/g, a surface area from 25 to 1200 m 2 /g, and an average pore size of higher than 2 nm, and wherein the silica-alumina has an X-ray diffraction pattern, which does not exhibit any diffraction peaks with a width at half height less than 1.0 degree of arc (measured over the double diffraction angle).
