New porous silicate materials and their uses as catalytic systems for diesel improvement

摘要

2) Multifunctional silicon-based porous catalytic system comprising at least one porous catalytic support structurally comprising silica and at least one other metal or non-metal oxide chosen from aluminium, zirconium, and boron, said catalytic support being synthesised together with one or more surface active agents, and at least one or more catalyst chosen from among metallic elements of columns 8, 9 and 10 of the periodic table of the elements. 3) The catalytic systems are useful in hydrogenation and/or decyclisation reactions of (poly)aromatic compounds, especially for improving the quality of diesel fuels and increasing their cetane number.
