METHOD OF PROCESSING HEAVY OIL STOCK ON A PROTECTIVE LAYER CATALYST Russian patent published in 2019 - IPC C10G47/16 C10G47/12 C10G47/00 

FIELD: oil and gas industry.

SUBSTANCE: invention describes a method of processing heavy oil stock on a protective catalyst bed, in which heavy oil feed is passed through a fixed catalyst bed at temperature of 300–600 °C, feed rate through catalyst of 0.2-2g-feedstock/g-catalyst/h, in the presence of hydrogen fed under pressure of 8–15 MPa, characterized by using a catalyst which contains aluminum oxide as the support and the active component is calcium and / or magnesium compounds, calcium not more than 10 wt%, magnesium not more than 10 wt%, catalyst has macropores which form a regular spatial structure, wherein macropore fraction with size in range from 50 nm to 15 mcm is not less than 30 % in total specific volume of pores, catalyst has specific surface area of not less than 100 m²/g with an outer surface portion of not less than 50 % and a specific pore volume of not less than 0.1 cm³/g.

EFFECT: cheap method of preparing heavy oils for their catalytic hydrotreatment and longer service life of the catalyst of the protective layer under severe hydrotreatment conditions.
