HYDROTREATING CATALYST CARRIER Russian patent published in 2020 - IPC B01J35/10 B01J23/882 B01J21/12 B01J21/02 

FIELD: chemistry.

SUBSTANCE: invention relates to a carrier for a hydrotreating catalyst for hydrocarbon feedstock, said composition comprising, wt%: silicon dioxide SiO₂, which is an amorphous phase and having a particle size of 3–20 nm – 2.0–20.0, aluminum borate Al₃BO₆ with norbergite structure – 5.0–25.0, γ-Al₂O₃ is the rest. Aluminum oxide borate Al₃BO₆ with norbergite structure, which is part of the carrier, is particles with size from 10 to 200 nm, characterized by interplanar distances of 3.2 and 2.8 Å, with an angle between them of 53.8°. Carrier has specific surface area of 240–270 m²/g, pore volume of 0.5–0.8 cm³/g, average pore diameter of 7–12 nm and is particles with cross-section in form of circle, trefoil or quatrefoil with diameter of described circumference 1.0–1.6 mm and length up to 20 mm.

EFFECT: technical result consists in creation of improved carrier for hydrotreating catalyst.
