Silica-rich carrier, catalyzer for heterogeneous reactions and method for the production thereof

Abstract

A silica-rich support and a catalyst containing the silica-rich support and a catalytic component. The support has a specific structure characterized by a set of claimed physicochemical properties: in theSi MAS NMR spectrum the state of silicon is characterized by the presence of lines with chemical shifts −100±3 ppm (line Q) and −110±3 ppm (line Q), with the ratio of the integral intensities of the lines Q/Qof from 0.7 to 1.2 (FIG.); in the IR spectrum there is an absorption band of hydroxyl groups with the wave number 3620–3650 cmand half-width 65–75 cm(FIG.); the carrier has a specific surface area, as measured by the BET techniques from the thermal desorption of argon, S=0.5–30 m/g and the surface, as measured by alkali titration techniques, S=10–250 m/g, with S/S=5–30.
