CATALYST FOR HEAVY CRUDE OIL REFINING PROCESS AND METHOD OF ITS PREPARATION (VERSIONS) Russian patent published in 2019 - IPC B01J23/28 B01J23/74 B01J27/51 B01J37/04 B01J37/10 B82Y40/00 C10G11/02 C10G45/08 

FIELD: chemistry.

SUBSTANCE: present invention relates to a dispersed catalyst for upgrading heavy oil stock, which is nanoparticles based on molybdenum-containing phases formed "in situ" when upgrading heavy oil stock in the presence of water, according to the invention, the catalyst additionally contains nanoparticles of a Fe, Co or Ni based catalyst and has a MoS₂/MoO₂ + Me_xO_y and/or Me_mS_n composition, with MoS₂ 3–78 wt% phase content, the balance is MoO_2, nanoparticles of cocatalyst have composition Me_xO_y and/or Me_mS_n, where Me = Fe, Co, Ni, and x, y, m and n can vary and depend on metal oxidation degree and catalyst formation conditions, wherein particle size based on molybdenum-containing phases is 6–380 nm and size of particles based on Fe, Co or Ni is 2–366 nm. Also disclosed are versions of the method of preparing said dispersed catalyst for upgrading heavy oil feedstock in the presence of water formed "in situ" under conditions of refining process.

EFFECT: obtaining a bifunctional catalyst for upgrading heavy oil stock, having high activity, selectivity as to output of light fractions and conversion of high-boiling fractions of heavy oil stock.
